I once had a pair of big Wilson Alexx driven by 2 pairs of D’Agostino Momentum M400 monoblock amps with the ARC (Audio Research) Ref 10 linestage preamp and achieved excellent results. At the time I was using all Transparent Opus cablings, Kronos Pro turntable w/ 12" Black Beauty tonearm, Air Tight PC-1 Supreme mc cartridge & D’Agostino Momentum phonostage pre served as analog front end source components and the DCS Vivaldi full four stacks (Vivaldi masterclock, Vivaldi upsampler, Vivaldi DAC, Vivaldi CD/SACD transport) served as digital front end source components.
I highly recommend the ARC Ref 10 linestage preamp paired with either the D’Agostino Momentum M400 monoblock amps or the ARC Ref monoblock amps for your Wilson Sasha DAW speakers. For digital front end source component(s) I highly recommend the latest EMM Labs DAC or its CD player. ARC & D’Agostino gears pair really well with Wilson Audio speakers combined with Transparent cablings. Ayre, Vitus Audio, VTL, VAC, Luxman, higher end Naim 500 series separate gears will also pair well with your Wilson Sasha DAW.
Remember, your front end source components, whether digital or/and analog front end components, are the most important components in hifi chain.
The Naim 500 series separate gears will also pair well with your Sasha DAW. The Naim 500 series separate gears comprise of the following :
* Naim ND 555 digital streamer/DAC with its external separate Naim 555 PS DR power supply unit (psu).
* Naim NAC 552 linestage preamp with its external separate 555 PS DR psu.
* Naim NAP 500 DR power amp with its separate external 555 PS DR psu.
The NAP 500 DR power amp is a true dual monoural design configurations with left & right channels are encased in separate chambers and are completely isolated and independent from each other with its own independent power supply and voltage regulations for each channel.
These Naim 500 series separates will sound highly musical on your Sasha DAW speakers.
For these Naim separate components you must use DIN connections to connect between components as it will make a big difference sonically, will sound better than using their RCA single-ended connectors. DIN is Naim’s proprietary connectors and is their XLR balanced version.
I am a big fan of Naim Audio. I’m also a fan of D’Agostino Momentum & Relentless series, ARC Reference line, Linn, T&A, Vitus Audio, Tidal, CH Precision, Accuphase, Luxman, EMM Labs, MSB, Soulution, MBL, Audionet, DarTZeel, Burmeister, Chord Electronics, Lamm, VTL, VAC, BAT, Cary Audio, Ypsilon, Ayon, Pass, Levinson, Boulder & PS Audio BHK series among others.
