I am posting here for those who browse this thread. I recently purchased a mint condition Audio Research LS7 linestage to use with my modified Playstation 1. Even though it sold as an "entry-level" all tube linestage in ARC's line-up back in 1995-1997, this is an excellent linestage and allows all the detail through from the modified Playstation. Not only do I get exceptional solid bass and treble extension, but I also hear greater timbral detail, more space between the instruments/performers and that holographic soundstage that tube amps provide. The LS7 is transparent, and that added gain really makes a difference in extracting the most out of the Playstation.
