I have owned the FS preamp, but the Presence Delux 2, and Avalon Eclipse speakers. I have heard Vac Rennaissance amps for extended periods on two different occasions. I own K-S Emotion, and still run it through my system. FWIW , I own the Vac Phi 300.1, and they do not have the inherent body and texture that the Rennaisance 300b amps have. Call it coloration, or what have you. So, you are definitely getting depth and body from the amps. I did feel the FS PD 2 did not ad any colorations, quite neutral IMO. You could try a another cable. It would be the easiest experiment, but the K-S is very good.It is a tad warm perhaps, but lets all the detail through. Here's a curveball. See if you can try a Shindo preamp. I am just not familiar with the Avalon Eidolon Diamond, but I understand it is one of the best out there.
Need Cable recommendation for VAC/Avalon Combo.
I am looking for cabling suggestions for my current setup. I use a VSE modded 6+ Sony SCD-777, a First sound Paramount Preamp, and a pair of VAC Renaissance signature 140's feeding a pair of Avalon Eidolon Diamonds. I am currently using Kubala Sosna cables and I am looking for something with a little more body to vocals and a bit better depth and image solidarity. any suggestions??
