Thanks very much for the input. Johnnyb53 makes the point better than I did. Since the Adcom is now worh less than the speaker cable, it seemed time to upgrade. The Parasound Halo gets excellent reviews and seems reasonably priced. Would it work well with Jolida 5t? I have also seen the Marantz PM-15 S2 available still in my price range but twice the price of the Parasound. Which might be a better fit? The Luxman would be great but it's out of my price range.
Warm Replacement for Adcom GFA 545 II
I recently upgraded speaker cables and interconnects in my system and it revealed harshness of the Adcom. My system: JM Labs Daline 3.1, Jolida 5t (upgraded), Moon 100 d DAC, and Apple Airport wireless. Cables are Audioquest 8 cv and Audioquest Diamondback. The brass instruments became too harsh and fatiguing to listen to. I listen primarily to jazz, vocals and classical. I would also consider an integrated amp and replace the Jolida. I have no particular budget, but do not want to spend more than would make sense in the context of the overall system. Thanks very much for the advice.
