Help in selecting 1 of 3 amplifiers


I’ve narrowed my choices for a new integrated amplifier to 3: Peachtree Nova 125 se, Rogue Sphinx, and Wyred 4 Sound mINT. The amplifier will be paired with Kef ls50s and play mainly digital files either from an Onix XCD-88, or an SMSL Sanskrit external DAC (won’t use the external if I get the Wyred or the Peachtree). What are your thought on choosing one? I can’t audition any of the amps where I live so I’ll be buying it blind, umm unheard?

the room is on the larger side since it’s a combined living room and kitchen 15’x25’. The speakers will be in a built in wall unit. Acoustically the room is pretty good, even our Samsung tv sounds darn good, so I’m not worried about the ls50s being unable to fill The room. I’m trying to keep the cost down so I’ll be picking it up used, if Zi can find one. Help me pick the winner!

What is your budget? For my money you can't get a better DAC at ANY price than the PS Audio DirectStream DAC. Sublime. Converts digital to DSD which simulates analog on an oscilloscope. Go to their website and check out the reviews, videos, etc. I run Nordost Heimdall 2 balanced cables out from the DAC to a Krell Foundstion and it's pretty sensational....and reliable.  

I suggested the wireless active LS50.
Then you at the mercy of class-D amps, like em or hate them.
The tweeter is Class AB powered and the woofer is Class D powered. 
The LS50 active has a 12 month warranty...a lot can go wrong with active stuff crammed in a tiny spot. 
I've heard the ls50 with an NAD 326BEE and was pretty impressed. I imagine the Yamaha AS501 - 801 series would work well too. I recently purchased a Teac AI2000 used on here that I intend to eventually pair with ls50's and expect similar results. 

Try the Ming Da tube intergrade amps. There rugged and reliable. Dead quiet and clear as a moon lite sky. Bias is easy and do it once every 6 months , like my sex life !
I had the KEFs ls50s paired with the Rogue Sphinx for a while.  In my smallish room, it was a bright combination.  (Some people love this pairing, but I've also noted others who reported it was bright.)  I now have my KEFS paired with the Vinnie Rossi LIO, which is a magical combination (although the LIO is quite a bit more $$$ than the amplifiers on your list.)  Closer to ones you are looking at, I have heard the Schiit Ragnorak is a great match.  Since Schiit offers a trial period, it would be easy to try it out.  Good luck!  Margot
