15 ohm speakers yea or nay?

I use 16 ohm speakers because my amps like them.

Or,...you could say that I use OTL tube amps because my speakers like them.

Yogi, I just purchased a pair of Q7s what amps do you like with them? Cables ? I'm using a Belles 22a pre and 150 ref2 amp. Sounds good but room is really bad very lively. You've had so many different units what are your thoughts?

@brianportugal

I sold the Q7. I was using Quicksilver 70 watt tube amps with Audioquest cables. The Q7 is as good as any of that type of speaker. I replaced them with the larger Harbeth HL5 super plus. The Falcons are very lively forward sounding compared to my Harbeth P3esrs. BTW, after the holidays I will be selling the P3s. I hope the Falcons work out for you!

Yogi, what do you think of the bigger Harbeth. When I was in New York I went to Park Ave  and one of the sales people said of all the Harbeths the ones you purchased were the best better than the 40.2  etc. 

I may need a bigger speaker for the area. The listening area is 9x13 but it opens in behind the listening area and to the side of the listening chair. How do you determine if a larger speaker is needed?
