Best Integrated All-tube Amp?

Hi,

My question: What are the best (and affordable) integrated tube amps in your opinion? (Not hybrid. All tubes.) Specifically, the best single-ended triode with zero feedback and ideally decent wattage.
So far, my list has only two:

1. Viva Solista. The problem with this one is that it simply gives you 17 wpc. It is way more powerful than most other amps that claim to have more power, but still I doubt it can drive extended low frequency speakers. (Currently I own Triangle Antal but in the future I might upgrade to deeper bass.) Nevertheless, I prefer sensitive speakers
2. McIntosh MA2275. I tested with B&W 800 and sounded awesome. But still it is not single ended (it is push-pull) and as far as I know it has some negative feedback. Plus, it a bit too pricey. (So is the Viva.) But I am still willing to consider.

What is your list, and why?

THANKS!

Josep

The Bel Canto SETi40 fills nearly all of your criteria. Uses 2 845 tubes and provides 40 WPC Pure Class A, zero negative feedback and and has a remote. Mark, at Bel Canto provides exceptional Customer Sevice and Bel Canto are an established firm.
Not cheap, but used, it is affordable. Read the reviews on Google.

I am not aware of an integrated amp that meets your requirements (single-ended, triode, 300B-based, class-A, no negative feedback, low distorsion, point-to-point wiring, good bass, and a well-known brand), especially one that is "affordable", whatever you mean by that.

The VAC Avatar is about the only thing that comes close, and I believe it is $3k-$4k used. The VAC Renaissance 70/70 Mk. III amp (not integrated) meets all of those requirements other than being single-ended (it is push-pull), but costs $5k-$6k used and you would need a preamp. The VAC amps do come close to the single-ended sound and avoid the significant disadvantages. Singer in Union Square carries VAC -- ask for Dave Lalin.

I agree with the others - you have way too many requirements. You are making yourself overlook many good options (like the Mc2275). I second the Jolida 302b which is cheap and comes surprisingly close to fantastic sound quality. I have one in my audio room now and it was a shock to me. At its price, you could try it at least.

Don't get hung up on circuit design details (I am an electrical engineer). There is more magic involved that you think and basing your decision on your criteria is doing you a disfavor. Trust your ears instead. If you love the Mc, go with it. Good luck! Arthur

I've owned the Rogue Tempest and loved it. One of those components I wish I still had.
