New Integrated amp recommendation

OK, Integrated, with DAC and Phono, lots of power

btw,

I love the sound and features of my Little Luxman, and the 505,7,9 z  would be amazing

however, unless more efficient, i.e. horns, in that large space, I would want more power for your Revel speakers.

505, 507, 509, the difference shows up more at lower impedance 4 ohm output, do the Revels have low impedance dips?

Here are Stereophile measurements from the 228Be that likely has similar specs to your speakers, and given this I’d want more juice than the 505z can provide…

My estimate of the F228Be’s voltage sensitivity was 89.1dB/2.83V/m, slightly below the specified 90dB/2.83V/m but within the margin of error. The impedance magnitude remains below 8 ohms for the entire midrange and bass, with minimum values of 3.42 ohms at 98Hz and 3.55 ohms at 290Hz (fig.1). There is also a demanding combination of 5 ohms magnitude and 39.5° electrical phase angle at 390Hz. While its nominal impedance is specified as 8 ohms, the Performa F228Be would work best with an amplifier that’s comfortable driving 4 ohm loads.

Given what you’re looking for I was also gonna recommend you look at the Coda CSiB and saw this used one available, which if I were you I’d strongly consider.  Hope this helps, and best of luck.

+1 on Anthem STR. I had it in my system for a couple of years and found it to be an excellent choice for the money, but also an absolute terms. Produces  a natural, detailed sound, well powered and superb build quality. Worth checking out
