Modified PS Audio Trio C-100 Integrated Amplifier

markmarc

After five years in my stable of reference review gear it's time to move on. Therefore, I'm selling my very minty Trio C100 for $850 + shipping(last new price was $2000. Rarely found on the used market, the modifications were designed and done by the actual designer of the stock model Rick Cullen. Below are the various modifications. You can read my review of the unit at: www.affordableaudio.org/aa2008-01.pdf. The unit ships in its original box with remote and manual. The actual amount of usage is right around 400 hours, as it was never the main amp, but a reference sound unit when comparing with ICE power. I had no problem driving my Magnepan 1.6's which create difficult loads, though I didn't find it an absolute terrific match.

Payment is by Paypal, shipped from 97223. Box measurements and weight will be posted this evening.

any idea how it would sound paired to kef r series speakers. I am just wondering if this would be an upgrade from what I currently have which is rotel rb990bx rc990bx pre pro combo.

Eduardo:
Well, you're giving up 100wpc a side in a switch, and will come out ahead if you sell your combo. Having had a recent series Rotel in my home (1520 integrated), I would venture to say the Trio C100 will have blacker blacks. The key to ask yourself is whether the KEF's and you need such power.
