Rated 8 because I’m the second owner.
I previously owned the non-LFP-V version of the Signature 30.2 Integrated and thought it to be a fine amp and a very good value, but felt some of the rave reviews were a little over the top . . . it later lost a shoot-out with a 300B tube amp that I used for a while until that amp lost out to the significantly improved Sig 30.2 LFP-V.
In Vinnie’s (talented designer and straight shooter) own words from the owner’s manual, improvements over the previous (non-LFP-V) version include: greater dynamics; tighter, more resolved bass; more open and extended treble response; a more lifelike musical presentation; improved tone and harmonic richness; a taller, wider and deeper soundstage; improved PRaT; improved retrieval of fine detail; ability to fine-tune via tube rolling.

At my asking price, I'll cover Shipping and PayPal fees . . . and include your choice of tube from my other ads at 50% of asking price.
