Spectral audio today

D'Agostino mono amps would be a better choice Solution is accurate but very dry sounding and very overpriced. D'Agostino has better stage,bass detail,and depth and is far more musical.Its your money good luck. 

I must agree with listening impressions posted by ebm. I’ve heard Soulution amplifiers on about 4 or5 different occasions (Audio shows) and the overall sound was consistently dry and clinical. It’s hard to determine how much contribution the Soulution electronics provided. This sonic character was consistent in different rooms using different speakers. Some would say that they’re accurate.

 I’d say their presentation was sterile and lacked a musically emotional connection.YMMV. On the few occasions I’ve heard Spectral I had a similar impression. Hearing the exact same Avalon speakers driven by Jeff Rowland components was far more enjoyable and emotionally engaging. This was some time ago but the contrast was strikingly stark.

From what i know for Spectral to sound right you need to get the preamp, the poweramp and the matching MIT Spectral cables.You also need to get the right speakers, Wilson Audio does work well with Spectral just like Avalon.Unfortunately many Spectral dealers around the world never managed to setup properly a Spectral system in the past, this gave a bad image to the brand.Today they have very little distribution even in the US.If things get better with COVID i will try to visit Audio Graffiti in Italy for a listen.

When I heard Spectral at CES years ago it was an all Spectral system driving big Avalon speakers.  The room demonstration was conducted by Dr. Keith Johnson demonstrating his own Reference recordings.  He seemed quite pleased with the sound.  I wasn't.  Different people prefer different sonic presentations. Thieliste it's very possible you may love their sound. It just wasn't appealling to me.

Well Spectral is not on my shortlist but who knows if i have a chance to audition in the next few months.My next planned audition in november is Audionet Humboldt and Stern-Heisenberg combo, let’s see how that goes.
