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

Thank you all for your prompt suggestions.

Yes, Stevecham, I am looking for a 300B, but I am opened to other suggestions. However, I prefer Electro Harmonix gold pins.

But my main requisites are as follow:

- Single-ended
- Triode
- Class-A (the problem with the McIntosh MA2275) is that it is AB.
- No negative feedback
- Low distorsion
- Ideally point-to-point wiring
- Good bass
- And preferably a well-known brand. I say this because there are so many little companies that come and go, and then you have no good customer service
- And, why not?, remote

Are the Aronov or the Jolida zero-negative feedback?

PS. I am sorry if I sound so picky, but I really like the single ended triode sound and there´s gotta be something that suit all these characteristics.

I am overwhelmed (and humbled) by all your responses. I really appreciate them.

Most of you mention that single-ended amps have their own disadvantages. Which ones are they? I guess class-A circuitry does not last as long as AB, does it happen the same thing with single-ended vs push pull?

You guys are right about the price tag. Though price is a fuzzy line here. I mean, if McIntosh would make a 70wpc single-ended as well designed as the Viva, I would probably be willing to spend over 6-8 grand (used.)Specially if it is integrated (key variable when you live between NYC and Europe.)Plus, switching the voltage at a Mac is rather easy, since the tranformer accepts dual voltage.

Also,about trusting one's ear. Essentially, I must agree on that statement. But it is just too hard to go auditioning all these brands, even in NYC. Dealers just try to push their stuff and have no time for someone who just wants to sample their equipment.

Thanks for your honest feedback,

Josep
