Sweetest SET Amp below $5k


I'm looking for that velvety natural midrange so often talked about with SET amps. I listen to a lot of singer-songwriter style music, so vocal reproduction is top priority. I've calculated I need something in the range of 20 to 50wpc. My main speakers are Opera Quinta (6-8 ohm, 89db sensitivity), but the amps driving them do not have to produce the lower two octaves as they are taken care of by subwoofers. It doesn't matter to me whether the amp is stereo or are monoblocs.

So, what are the warmest, sweetest SET amps that I can find for under $5k or so, new or used? Any ideas will be greatly appreciated!

Thanks Matrix. I'll take a closer look at their stuff. I did find some discussion on their products here, but could not find that review you mentioned. Had you heard their 45 watt version? I have 6-8 ohm 89 db sensitive speakers (although bass duties are handled by subs), so the 45 watt version may be more appropriate. I find it interesting that the 45 watt version is only about $350 more that the 20 watt version. Why get the lower powered unit if it's so close in price to the higher powered unit? Have you needed to speak to them at any time? I don't like when a manufacturer does not provide a telephone number on their website.
I use similar sensitivity speakers 89db and 6ohms and I agree with you Smeyers that 20watts is a minimum for SET output. I use a Viva Solista, 22watt 845 SET with a sub out too. My room is 22 by 20 foot and it has great control over the speakers.
Unfortunately, 20watt, quality SETs, are'nt cheap. Quality needs large expensive output transformers. I bought my Solista for about$4000, which seems the norm for second hand prices. If you can find one, you will love it. Everyone who has heard my system has said, if you want to sell the amp, let me know
Thanks David. I have been hearing more and more how important the output transformer is and how expensive good ones are. Unfortunately with all the information and varying opinions around, it's hard to know what is really a good, well built amp, what is not, or what seems too good to be true.
