OP, OK I'll mention Raven. Love mine and 20 wpc in my midsized room seems plenty. 2w stand speakers at about 87db. Your room is15x15 and not sure of your next speaker's efficiency it might be a tad low on power. Raven does have 80hz hi-pass so they have more avail power and do well with subs. Roll a pair of quality NOS in pre spots and it shines. Used about $1800 - 2000.
The $10,000 Question
I've upgraded my upstream components, and am in the hunt for a new amp and speakers. There is a dizzying array of choices, and one could go bankrupt with the buy-try-return method. I'm looking for some guidance on amp-speaker combinations, either used or new, in the $10,000 range for both. If I can narrow the search down to two or three amp/speaker choices it would make the buy-try-return plan much more reasonable.
I prefer tubes and space is limited to an integrated amp. My room is 15'x15', and and I primarily listen to classical music at modest volumes (which would allow conversation if my wife yells at me to turn it down). I'm replacing 20+ year old Forest Totems and a Prima Luna Dialogue One amp. My upstream components are a Cambridge CD transport with a Jolida Glass FX III DAC, and a refurbished Sota Star with a Jolida JD-9 phone stage.
Thanks in advance for your insight and guidance.
