First foray into tube amps


I just read the thread on McIntosh and it has prompted me to start this thread.  I would like to try a tube power amp, but I have no experience with tubes.  For now, at least, I am pretty well settled on the rest of my system: Stirling LS3/6 speakers with dual SVS 3000 micro subs, Node 130 streamer with PD Creative/LHY power and English Eight switch, Bacch4Mac crosstalk elimination and DSP, RME Fireface dac/interconnect.  I’ll be replacing a Peachtree Gan1.  The room is 23x16x8 and is well treated.  I listen at low to moderate volumes, lots of vocals, blues, Argentine Tango, some classic rock.  I love that BBC mid-range magic, and think I want a little more warmth than I have now - but without giving up any precision or detail.  I find very analytical high end reproduction to be unpleasant, though.  On the low end, I dislike mushiness.  I really like bass details without slam - think of Holly Cole’s Train Song listening to those bass transients tail off.

So, I think that some tube amps might fit the bill and are within budget (say $5,000).  Here is my provisional short list: McIntosh MC275 MK6, Conrad Johnson MV60SE, Quicksilver Mid-Monos or 88 Monos, PrimaLuna Evo 300 or 400.  There are many others, and I’d welcome suggestions. I can’t tell if these or some other amp would likely have better synergy with my speakers/room/music preferences.  I realize that I may need to try several amps to find which one sounds best to me - but where to start?  Many thanks.

@treepmeyer ….Volti Razz, a Klipsch Cornwall or a Pure Audio Project Duet.

The Pure Audio is a panel speaker which generates energy front and back, so requires careful placement. I suggest further research on box vs dipole speakers.

I wanted the most neutral efficient speaker so I can hear and learn differences in tube amplification. When I saw Volti offer a couple of Klipsch transducers(driver) upgrades here, I got the impression that Volti was sonically superior. I later found out that Volti Audio’s founder, Greg Roberts, intentionally designs his high-end horn speakers to offer a more refined, higher-quality alternative to traditional Klipsch Heritage models.

I heard the Volti Rival at several high-end audio shows like AXPONA. They sounded great, clear, dynamic, effortless. I own the Volti Rival. Research in tube sonic magic led to flea watt amps 300b, 2a3, 45,50 tubes. I wasn’t sure if the 100db Volti Rivals can handle the very low ~2watt amps, so I reached out to Greg who replied it’s okay to use.

In investigation various tube presentations, I trying to not overly spend $ on tubes and tube amps. 

I’m now targeting the TEKTRON TK TWO 2A3/50S-I which can run multiple tubes 2a3, 45, 50, 300b. The Response Audio Harmonia v4 45/2a3/300B is another option for less money. I’m also targeting the DECWARE Model SE84UFO25 which contains extra various tubes for a good variety of sonic presentations- saves money on buying tubes, bummer it’s wait list ~3 years.

Good luck with your search 

I have owned a bunch of Audio Research gear.  I started out with the LS -17SE preamp and the REF 75SE amp, both of which were great.  I still think that REF 75SE was one of the best bargains in audio.  I now have REF 10 preamp, REF 10 phono state and the REF 160S amp.  I love the audio research sound.  I'm definitely biased, and i can't tell you that I've compared it to a lot of other tube gear, so I don't know if its better than some of the other suggestions, but will tell you I love the Audio Research gear.  

Tube amps are not that consistent like the solid-state amps. Tubes got aged over time especially for those power tubes. Periodic maintenenance is needed to keep the amp in good condition. 

I understand that this is a bit discouraging but this is very true indeed.

Look for a decent used Audio Research i/50. They appear frequently here and on eBay and AudioMart. It is a 50W push-pull design, 6550 tubes, useful interface and very good sound.
