I agree with other contributors, what a good thread. I am ashamed to say, I had heard little of 845's until the recent UK Hi End show at heathrow. Nick the importer of Viva amps was using the Solista integrated to drive sensitive ART speakers in a very large room to very good effect indeed. That's just 17 watts and more than enough. i have always equated SET amps with 3 to 8 watt 300B amps and have not been that impressed I am afraid. Not bad, but certainly not the drive of the Solista. Well I have just aquired a Solista on the Audiogon site, it is an evil looking brute, but managed to persuade the wife it had a sort of industrial chique. Who can resist the thought of Italian design. I am looking forward to its arrival, yet another bargain for a UK buyer. Not that I'm gloating, but the price of the dollar makes direct imports very tempting.
