PS Audio BHK 300 mono VS Modwright KWA 150SE mono VS D'agostino Classic stereo

+1 melbguy1.  

I am very happy with a pair of Modwright KWA150SE driving my B&W802D2's in bridge configuration. This amp is grossly underrated, easily one of the best solid state amp under $10K. The holographic imaging, tubey mid-range, fabulous highs without any edginess and superb tight bass. The build and finish quality is also unprecedented at this price point.  

Try to audition these amps in bridge mode with LS36.5 and Elyse DAC and be ready for a magical ride. 

thieliste, I have not tried the 36.5DM power supply.  I did discuss the separate power supply option with Dan prior to buying the LS36.5. According to him, it's a whole another level of performance.  It's on my short list of future upgrades.

I don't know your rest of the setup but If you're considering LS36.5 or any other preamp, make sure it has line level outputs to drive a sub. Dan customized my LS with a fully balanced output in parallel to drive my JL Audio F212v2. The sub adds a another layer of dimension that IMHO, no speaker is capable of producing.

Glad to hear about your audition with Ypsilon went well. I have recently gone through the similar experience but at a much lower price point.

My dealer brought in McIntosh C2500 / MC601 mono's to pair with my B&W 800D2’s. Right off the back, I was impressed with MAC’s transparency, natural sound and the deep low end. This is by far the best imaging I have heard from my 800’s. C1100T is next on the audition list.

Cheers!
