Wyetech Labs Ruby Std preamp - any views?

Very dynamic, utterly transparent and musical, I find no fault with it. Pairs well with my Sapphire mono blocks Roger also designed... but I believe a mate with his new Ruby monos will compete with anything out there.

Know nothing of the circuit sorry, but Roger has an exceedingly keen ear for great tone... all his products make music.

The Ruby pre's most obvious trait is its explosive dynamics. Far more powerful than my Supratek Cabernet Dual with separate tube-regulated power supply, which is no slouch. Odd that, given the Ruby's lack of separate PS...

The tone is extremely detailed and transparent, bass is well resolved, treble is airy and silky. If I could detract at all, it might be that the tone errs slightly to the warm (musical) side of neutral, which I prefer anyway.

Yeah somewhat contradictory... Transparent to me means detailed without the artificial edge you often hear in high NFB solid state. Warmth to me denotes naturalness, what we hear live. The Ruby's warmth also reveals the natural body of a tone, and preserves a beautiful harmonic portrayal. These qualities combined with its strong dynamics serve piano particularly well, with its percussive nature projecting effortlessly into the room. Quite engaging indeed to hear reproduced music come to life.
