For anyone who moved from tubes to solid state — a question


I'm the happy owner of a fairly new tube preamp and monoblock amps. I love it and have bought new tubes. To have another option for warmer weather or possibly a second listening room, I got a very good solid state integrated. I've run the tube preamp with the solid state amp and it sounds quite nice. I love all tubes, too.

But this question is for you. Please forget the convenience factor for a moment, including the issue of tube replacement etc. Also, forget about those cases where you bought new speakers and needed more power, etc.

Assuming you had quality tube gear with sufficient power — here's the question if you abandoned tubes for SONIC reasons:

What what is that tubes couldn't give you?
What did your solid state gear do for you which was so much better that you divorced to marry anew?

I'm curious about what people list as the positive sonic reasons they love solid state (including A, AB, D, etc.).

Thanks.

When I listen to my tube based system, I get emotionally carried away. When I listen to my SS system I get interested. For me, emotional is more true to the essence of the music.

My Sansui must be a "tube" amplifier without me knowing it....It does not sound only detailed but visceral also and warm....

:)

I truly think that the differences that a good embedding can make is over the relative differences betweeen Tubes and solid state.....But i dont have experience with high end tubes amplifiers then....... :)

It is just that i cannot think that my sound from the sansui is in any way like some describe S.S.

Perhaps some dont know it Sansui takes 25 years to reproduce exactly one against the other their best tube amplifier with their best solid state.... Their goal was to reproduce the tube amp Sansui in their Sansui S.S..... That was a complete success.... I dont have the link to the video tough no more....

Instructive to understand a difference that only relatively exist not by virtue of an eternal difference in design but by accident and tech history...

A good embed S.S. amplifier and a good embed tube amp. are on par.....

The question must be: is it reallly rightfully embedded mechanically, electrically, and acoustically? The question is not wich is better a S.S. amp or a tube one.... It is relative to their quality/price ratio and finally to their embeddings in the system, room, and house.....Theorically we can design a S.S. amplifier to sound like a tube amp, Sansui has proved it long ago....
Tubes and SS are a different paradigm. They approach producing music from different perspectives. My understanding is that tubes are a more visceral experience and SS more intellectual.

This type of generalization is common in a variety of audio debates, but not really true. The right SS setup can be emotionally very engaging, and tubes can leave you cold in the wrong setup.
I think we've reached the logical end of this topic, regarding the big picture.

We have these two recent statements:

best of breed tube and solid state are very close now, and ever converging

And the opposite claim:
Tubes and SS are a different paradigm. They approach producing music from different perspectives. My understanding is that tubes are a more visceral experience and SS more intellectual.

Be that as it may, I'm still interested in what someone specifically gave up in order to gain with SS. With as many variables controlled as possible. But maybe this well is run dry.

Like someone else already said here, ZOTL technology seems to be the way to go without any negative  claimed by the 2 camps against each other, in the tubes versus S.S. debate....

I want one and i accept donation.... :)
imagine an easy load no bizare phase angles, gentle slope filters speaker with power factor corrected feed forward amp below 100 hz with 11 bands of analog EQ...amp matched to sub, sub matched to amp, then the high pass goes to a hybrid amp with tube front end, liquid cooling for rock solid bias ( think that thru ), bipolars in a cyclotron floating ground output and a bunch of other neat tricks of amplifier supremely matched to speaker load and sensitivity..

Vandersteen 7 speaker and Vandersteen 7 amp

you can get close for $30k with Quattro and Model 5 amp

as othersstated, but i will paraphrase, unfair advantage when you can purpose design an amplifier for the load, and in this case split the load 
I will say 20 series Ayre amps are super great SS also, very liquid, very musical, harmonically dense...

Thing is both of these can be true. Depends on the amps. People can jump and complain but the thing is some tube amps measure as good as SS amps and some SS amps measure as bad as tube amps. The traditional "tube sound"  smoothness is due to the harmonics they distort. It has a pleasant sound that most people enjoy especially with analog. That digital "glare" some complain about is because we're used to hearing the distortion of vinyl and tape played through tubes and think somehow that's the way music should sound. If someone thinks digital glares or is hard edged and difficult to listen to for long have a 3 piece jazz ensemble in your living room and listen to the sax or trumpet and tell me about glare or next time you're in a concert hall listen carefully to the violins and flute/piccolo section. So to cut to the chase to me music sounds more real, instruments naturally have ringing and glare and good neutral SS reproduces it better. 
What did I give up? Distortion. 
...and then there's the paradigms of amp choice and the speakers it drives....

There's been a lot of waxing wonderous of 'this' driving 'that'...and it generally is tied to the tube v. silica...which, is really actually rather special, imo..

The SET that can make this driver sing like a lark....but driven by SS type anything will make some prefer to have cellophane crushed around their head....

The SS that makes that driver sound like the sax solo is getting etched into the backside of your skull....but it feeeelss  sooo gooood.  Swap...

...and you'd rather have a root canal anywhere but your ears.

It's real subjective....and even then, subject to your listening den/torture chamber.....

The jury's still out on hybrids as far as I can tell....

The 'Everyamp for Everyone'?  Or the 'Nothing for Nobody'? *L*

A 3 position switch: T/SS/STS ?  Any love/hate/meh relationships out there?  Curious minds are nosy...*S*

What did I give up? Distortion.
Distortion is what causes solid state amps to be bright and harsh.
Distortion is what causes solid state amps to be bright and harsh.
Distortion is what causes solid state amps that measure as bad as tube amps to be bright and harsh. Take something like the Benchmark AHB2 noise and distortion is below audibly of humans. No tube amp can come close to it and very few SS amps. 
This IMO is a general question as it does not apply to all amps SS or Tubes.  My old Lafayette tube amp will probably out perform most SS amps. My Class A amp sounds different and each has advantages the other does not.  I prefer this tube amp myself but it is a monster weight wise.  I build a hybrid power amp tube input and bi-polar transistor output.  It is a point-to-point wired amp using customer transformers, chokes, top resistors and capacitors.  You cannot find another amp build like this.  It sounds like a combined SS & Tube amp.

@mglik - maybe a true Class A amp would come close.

Happy Listening.
I switched back to solid state because it produced better clarity. That's important if you like large symphonic works with lots of subtle detail. Tubes smeared the detail

Take something like the Benchmark AHB2 noise and distortion is below audibly of humans
Yes- what is happening here is that this amp has enough feedback to sort things out. This value tends to be north of about 35dB. By 'sort things out' I mean that the feedback value is so high that it can compensate for the distortion caused by the application of the feedback (which is what causes brightness in many solid state amps going back 50 years); its an impressive accomplishment.
It's always interesting reading when designers work very hard to make solid state and hybrid amplifiers to "sound like a tube amp". 

While I like and rotate both, when its time to simply become most engaged listening to the music, its all tube.  
It really comes down to preference and system compatibility; my 25 watts Triode KT88 is way more resolving and transparent than my 18 Watts Class A SS and this is at normal listening levels; the clarity is just amazing and I could not believe that the Class A SS was masking that much detail...

It’s hard to produce the dimensionality and musicality of tubes even though a tube pre and SS will get you in the realm but it still does not check all boxes for many tube fans, to include myself 😄

It’s worth pointing out that the tubes "you" were using smeared the detail, but that’s certainly not the the case  universally with all tubes ....in many cases its just the opposite with good examples of tube amps. One of the down sides of tube amps is that they do need to be maintained and monitored, and if not, the result can be less than optimal. That, and not all tube circuits are good tube circuits, and not all tube circuits are a good match with all speakers.
I loved the sound of my tube gear.  I put up with the inefficiency, meaning the furnace-like heat.  I began to wear down, though, from the cost of re-tubing and once having to ship the amp back to the manufacturer for repair when a tube blew up.  But I finally decided to move to solid state when I realized how often I was not listening to my system.  I never turned it on unless I had an hour or more to listen...took a while for it to warm up and sound it’s best, and I was concerned about shortening tube life by switching on and off for short intervals.  Got a half hour before we leave the house?  Forget it, no music.  Want to hear that one song a couple times you’re trying to learn on the guitar?  Forget it, no music.

My solid state gear sounds great and I listen to it much more than my tube system.  Solid state fits my life better.
This may not *exactly* answer the question, but I thought it was relevant to the spirit of the conversation: I’ve used and owned dozens of different amplifiers (tube, ss, and hybrid) with a variety of speakers over the years. My primary speakers have (almost) always been Magnepans, though I’ve had plenty of cone/horn speakers to play with as well. I started out with solid state amps, tried tube amps, went back to ss, but have returned to tubes. *Some* tube amps have a looser bass response, and *some* ss amps are overly etched and coarse sounding. Maybe even *most*. But after trying different types of amplifiers with a variety of speakers (but primarily Maggies), I own only tube amps now. They (the ones I’ve kept, at least) just do something special handling the signal that is missing with the ss amps I’ve used. My current main amp is a Music Reference RM-200.. and honestly, my Maggies have never sounded better... So for ME, with my choices of music, at my chosen volume level, and my speakers.. I prefer tubes. The important qualification is *my music*, *my speakers*, etc. I don’t think this is something that one listener can answer for another. I just wanted to share my own journey and conclusion (for now, lol). There are going to be trade offs with every scenario, and one has to choose which combinations meet one’s own expectations. In my opinion, of course. 
@krelldreams Thanks for sharing. You say you went "back to tubes" but the main amp you mention is a hybrid, no?
I think 77jovian basically hit the nail on the head... it’s the ‘labor & time involved’ with tube amps that are the most dissuading factors to tube amp listening. My TRL monos are best described as big, heavy, hot, multi-tube high powered monsters ... they need time, love, and attention and are the best sounding amps I’ve ever heard drive most anything. Listening to them is “an event”.
When I want to catch a “quick hour” or so it’s “Not Applicable”.... hence the need to rotate monthly (or thereabouts) with my flick-of-a-switch SS amp.. a pair of Krell FPB 350 MC monos. They give me 90% of the tubes plus the SS virtues as well and the transition takes me 20 minutes a month or so to do. I wouldn’t want it any other way. ( Speakers are rebuilt Apogee Duettas...). 
Lissnr do you have the big 400 monos or the bigger 800 monos? How is the bass with those compared to the krell monos?
Hello invalid, My experiences with Tube Research Labs (TRL) date back quite a few years starting with the “Dude” preamp and a pair of GT200 monos which I still use today. I have also owned the Stereo 100 . I have fellow TRL owners that have been friends / listening buddies for as many years and they each own the GT 400’s.   Originally equipped with KT88’s all the TRL’s are flexible with output tubes as they were essentially “overbuilt” by design (and literally their construction as well) such that the KT150 or KT120 are the current ‘go to’ tubes for each of us. The 150’s ( my choice) add about a 50% increase in output power over the ‘88’s and the KT120’s not quite that but still noticeably above the 88’s.    I am also an “Apogee guy” and the vast majority of my own system has revolved around either [rebuilt] Divas or Duettas. My friends have run their 400’s into plenty over the years as well including a variety of Sound Labs including A1’s, A3’s, Ultimate 1’s and 2’s, Focal Grand Utopia BE’s, Nova  “” “”” as well as Martin Logan CLX’s and more. 
  As for the 800’s... that’s a whole other story. I’ve never heard them but my friends have. Incredible. 
There is a guy on another forum that biamps with the 400's and the 800's into a pair of apogee full range.
Looking closer at those TRL 200,400,800 amps, now I think I better understand what was meant earlier around "maintenance", and  "event" when firing them up.  Wow, that's some array of output tubes... 

Certainly makes for a case of owning a backup SS amp for non-critical listening times or non-winter months :) 
The best tube amps from Audio Research require an A/C system for the listening room.  Tubes are finicky.  If you want to hear great musical reproduction, all of the time, stick to really good trannys. 
Luckily, my tube amps are in a basement space that's always cool. Even when it was 100 degrees outside, things were fine. I agree with the issue of not warming up a room, though. If I was upstairs, I think a solid state would be a good backup for those warm summer months. At least for the power amps.

you are not a dedicated audio research tube amp lover unless you listen wearing a racing cool suit :)
When I first decided to replace my 3 way, 12" Fisher speakers for my Fisher quad system, I went to our local dealer in Boca Raton, and discovered Audio Research.  As a grad student, I was only fascinated, but not able to buy it.  They also sold the big Magnaplanars and Luxman.  For mere mortals like me, they had Phase Linear and Advent.  I bought four Advents, and  later replaced the Fisher quad with a Phase Linear 400, which really rocked with these stacked speakers.  I never ceased admiring Audio Research, and have heard their newest mono tube amps that require their own HVAC system.  Audio emporium's "museum"  lists my Audire amps as having "gargantuan bass", but these giant Audio Rsearch amps would still be my dream if I lived in Alaska, even for the bass.
