Any GREAT "sleeper" amps?


Looking for relatively unknown super steal deal tube pwr/int amps - around 60-150 watts?

Niles Audio SI-245. I was using this as a surround amp for the back two channels of a home theater setup, but now using it as a main amp for a 2nd system. Very powerful for its 45w/ch rating, very clean non-fatiguing sound, very well built (large transformers, can drive inefficient speakers, solid chassis), and has level controls for each channel. I think it's a great value as it's list price is only $400.

Yes, Cayin A 88-T. Just for your information, I am re-posting this (the original post was put up today for an AGoner who wanted recommendations, still it applies here too i think. In hoping that it may be of help. It is not as powerfull as what you are looking for at 40 watts, but just for comparison's sake, it smokes a previous Sim Audio Moon I-5 to shame both sonically and in subjective power.

Cayin A 88-T integrated, a TERRIFIC bargain. Grab one before the price goes up. I own this stellar amp, and it is a keeper, after owning a lot of pricier equipment.

I know, it's made in China...but this is a SMART amp and it sounds delicious with gourmet tubes, meaning getting rid of the stock tubes (although they are nice)and going a bit better. Partner this with a decent power cord - a MUST - and you are in business.

This thing has point-to-point wiring, a soft-start circuitry to extend tube life, a nice, small but chunky metal remote with switchable standard ultralinear 40 watts or triode 22 watts mode (not quite SET but close...) AND what I feel is truly exceptionnal build quality and parts selection for the price, leaving in my opinion at least, all the Antique Sound Lab (ASL) and similar amps in the dust in this departement.

Sound-wise, I really think you have to spend a LOT more money to equal it, and even more to surpass it. Very beautifull to look at, and very beautifull-sounding, I think it is a screaming bargain, and my guess is that one of these days, the price of these will skyrocket upwards when more of these will be in the market, and there is a bit more history out there, now that there seems to be (finally) a reliable distributor in the US. By the way, I did compare it to the Prima Luna, sorry, close but no cigar. As I said, my Cayin A 88-T is a keeper, something I have not been able to say in a very long time. Good luck!
The Music Hall Mambo is a killer integrated at $1300 that is rarely mentioned. 50wpc Pure Class A and overall larger cap value than a 200wpc Rotel. Dynamic, detailed and sweet sounding, what more could you want?
