You are correct tablejockey! I do have upgraded caps on the PL. |
Thanks motorway for your story! I bet the Carver 275 mates well with the PL preamp!
Each of these three amplifiers in my shootout are wonderful. I hope folks know the point is just to have fun. All of them are worthy of my long term listening room.
I'm 24 hours in, and I promise to hold back my subjective review until I can run through the same recordings with all 3 amps. I will, however, say the Carver 275 surprised me. It is super special. |
It has now been a month (about 5 weeks) living with these three amplifiers under the same roof. I have owned the PL since 12/16 and the Elekit since 12/17.
The PL has superb build quality, customer service, and features. It's sound in my system is so big and full. In fact, it can be huge. Bass is big and has much authority. Midrange is really nice, but better with some power tubes than others. I know folks always say the PL sounds best with EL34s. It does sound great. However, I think it sounds great with KT150s.
The PL crams a ton of stuff into the case. There's virtually no room to leave a pencil inside of the chassis. Packed. The PL is back breaking. It weights some 55 lbs--maybe more, I haven't checked in a while. The PL has a dizzying amount of power tube rolling possibilities! Huge selling point. The PL uses 8 power tubes and 6 preamp (2 gain/4 driver) tubes. Re-tubing and rolling is a pricey endeavor.
The Elekit is virtually featureless. It's designed as an integrated, but has no remote volume control. It has one pair (yes, just one) of single ended inputs. To say the PCB is thoughtfully laid out is an understatement: It's amazing. The Elekit design is really interested. It's solid state rectified, including mosfets! In a tube amp! Blasphemy. And, it has a touch of negative feedback applied.
The Carver is featherweight. I can lift it by its chrome protective tube bumper with 1 finger! It defies logic. The Elekit is no featherweight either. Those Lundhaul transformers weigh a ton.
The Carver has a nice piano gloss paint finish. I like it better than the PL and the spartan Elekit. All 3 amps have nice binding posts. The RCA jacks on the Elekit are not great. The Carver, while arguably nicer in chassis than the Elekit, is not nicer overall than the PL. But the PL is not a looker--in my humble view. The Carver, while not cheap, is simple and without adornment.
The Carver is the only one of the 3 that needs to be biased or isn't auto biasing. I was surprised at how easy it was to bias. The manufacturer says its fine to set it as low as 60 ma or as high as 120-the lower you go the more it is supposed to sound tubes and soudnstage is supposed to increase. I think that's a fair statement but I didn't hear dramatic differences.
On the PL, I dislike that the default setting is Ultralinear and you must have the remote to change it. My remote died and is out for surgery/replacement. As stated above, the Elekit's 1 set of inputs for an integrated is really a big sin of omission. It really needs to be an amplifier if it's only gonna have 1 set of inputs. I see no faults with the Carver on features. Build quality is solid, but maybe not as substantial as the PL.
Now onto sound. I'll try to put it into only a few key statements--rather than go on and on with audiophile adjectives.
The PL-- Easy to like. Big sound. Bold. Rounded edges here and there. Plenty of weight. Overall smooth, but it's not particularly detailed. It is, however, pretty musical. It's an easy choice. It doesn't offend and makes great music.
The Elekit--Super clear. If you stay well within the amps 9 watt limitations, it is super transparent and clear. Vocals and jazz sound amazing. It resolves detail wonderfully. It has a good size soundstage. Top to bottom, the sound is even, clean and understandable. It, too, is musical, and not super analytical despite its high resolution ability. I wish it had more oomph. Even though my speakers are around 100 dB efficient, they could use a bit more to get them running into stride.
The Carver--Sweet. My listening notes use the words "sweet", "boogies", and "this little amp" repeatedly. The bass is strong and well defined. There's more of it than the Elekit and it's better defined than the PL. Midrange is seductive. The highs swing and don't offend. I was surprised. Like the Elekit (but with more authority) the Carver has something lifelike about the sound. It's not that the PL sounds "fake" or bad in any way whatsoever. The Carver's sound (and pardon the bizarre metaphor) made me think the music was delicious on many listenings. I could eat it! My descriptions of listening session in my notes contain words like "juicy", "sweet".
I really like all three of these amps. I think the PL is a safe, solid choice-especially for my first tube amp in 2016. It's feature-rich, has unreal build quality, and sounds fantastic. The Elekit is a more specialized tool. If the PL is a nice daily driver and party amp, the Elekit is more intimate and for special listening sessions. The Carver is really something special. Personally, I like it a bit more than the PL and it has more versatility than the Elekit.
Each amp is a delight. I was a bit tepid that Carver could make a tube amp with transformers be this light and have this type of sound quality. If you're out there thinking about the Carver, don't let the lack of pro reviews steer you away. Buy from a dealer with a good return policy like Jim Clark or Music Direct. |
@jjss49 , yes you are exactly right. First, the PL always felt like it could be a super amp. It's Godzilla in size--well nearly. It's bold and refined. But, it wasn't that resolving--or at least with my stuff. It has always been thoroughly enjoyable.
I swapped out dozens of tubes with the PL. I spent too much.
As to triode v. ultralinear, I enjoyed both. I always wanted a variable dial that I could turn up/down to adjust feedback or bias. Having the UL/TR button was a gift. While I spent too much time debating which one I liked better, it was nice to have the switch as I sometimes simply used it as a "Loudness Button"--a la 1974. It just sounded lovely at low volumes in UL.
The Carver is running Tung Sol KT 120s--the only maker. The driver tubes are basic Electro Harmonix, 12AT7, and gain tube is 12AX7, Tung Sol. No fooling. Nothing special.
And to your point, can the Carver drive speakers with much higher demands than Cornwall IVs? I'd be more cautious as sensitivity drops as well as impedance. I would question that this thing could drive a medium plus load in a good size room. But, who what do I know? If I was in a smallish room I'd try this amp with any loudspeaker within reason....just to see because it's a sweet little amp that begs to be auditioned with all sorts of equipment.
Finally, yes, I think the Carver is more resolving than the PL. Mainly, I think the Carver has more texture and open space, while not sounding too airy, or something bloated. |
@madavid0, it's not accurate to say "it sucks" so I didn't say that. Trust me, if only this hobby were so simple. I wish it was as easy as, Amp A sucks, and Amp B doesn't. |
Yes, the Carver sound is not bland or boring here. It is, however, well behaved at all times. I haven't experienced any harshness. There's a special smoothness on the whole spectrum that sounds very sophisticated. That would be a turnoff if the amp didn't have such a high boogie factor to round that out. Marry those two together and it's a beguiling sound that romances me.
My sense is that Bob Carver really knows how to voice an amplifier. His amp really won me over with soundstage, imaging, and texture. Those three things come together in a holographic picture that I love.
Honestly, I cannot knock Prima Luna. It is such a wonderful product. Personally, I don't think that I need to pay for that build quality because I wouldn't keep the amp for 20-30 years. I'll also note, my only real knock on PL is subjective--I think their casework is strong and well thought out but not attractive. Personally, if I want to love a product for the super long haul, it has to have compelling/charming aesthetics. The PL just looks like a big boring black box to me. It feels and operates great. In the looks category I'd give it a solid B or B-. Again, this is my own subjective view.
I buy hifi from anywhere it is made. But, it's nice to know though that Bob Carver has his amps made in California--likely at the Wyred 4 Sound facility.
JJSS49's point about my speakers is a fantastic one--they are super easy loads. It would be interesting to hear the Carver with more difficult loads/less efficient offerings. The PL shines in that department. It can drive anything. I just don't know what the Carver can do in that area.

@crouse99 , I agree. I like it but I'm not a junkie for it. Before I got into horns and tubes, I was down the path of low efficiency, slick modern speaker designs that seemed to specialize in imaging and detail retrieval. It got to the point, in my system, where it started feeling like a parlor trick or gimmicky--well maybe not that bad, but you get the point. |
@jjss49 , once again I agree with you. Put me on your mailing list!
By the way, the Carver is staying in my listening room. Since the Elekit is such a specialized piece of equipment it has a place here. The PL is going! She served me well. |
@jjss49 , Sweet! Let her run!
|
@jjss49 , I would think the Carver 275 and the Spatials would mate well. I'm curious about your Harbeths. I cannot comment on compatibility of the amp because I'm driving the Cornwalls at 100dB sensitivity. |
@jjss49, Wow! Great assessment.
I agree with so much of the detail you pointed out. Wonderful review you did.
You put into better and very specific words what I was calling "delicious"--that midbass and midrange are seductive.
And, you are dead on in your observations on weaknesses--low level transformer hum (I actually called the company and swapped out units on this issue), RCA jacks are decent but not stellar, and if you really "look" closely the treble is A- but not A or A+. I should add, I can live with those things because this amp really swings and the treble and midrange are lovely in their presentation. I don't get tired of it at all.
Now, the question is (and it's a pricey question), if the Crimson 275 is 75-80% of the Crimson/Raven 350, what do those mono blocks sound like for $10k?
I'm glad you took the time to perform such a detailed review with different loudspeakers. I have only run the amp with Cornwall IVs, which are so easy to drive an alarm clock FM radio could power them.
