Here is a PS Audio GCPH Phono Preamp modded by Parts Connexion/Underwood Audio. It is the Level 1 modification. New price is figuring $1000 for the preamp and $700 for the mod. One audio magazine (Ten Audio) said the modded version equalled $3500-$5000 phono preamps. It is very nice. Warm, detailed, dimensional with defined and powerful bass. This pre is in marvelous condition visually and functionally. Includes remote, original box and paperwork. The Parts Connexion Certification Label is on the bottom of the chassis. Asking $650. Payment by Paypal only. Please pay within 24 hours of purchase. Shipping within continental 48 US only. I have it all boxed and ready to go. If you have any questions please feel free to contact me.
