Solid state warm up?

Phoenix,

If you leave the amp in standby mode, I'd think that obviates the need for warmup. I suspect the "mushy" sound lies elsewhere. The increased detail and subtlety you say you got seem at odds with mushy.

Quiet passages have much more low level detail with the BAT. There is more texture overall. When the music gets complex and louder it gets the mushy sound.

I give my solid state CD player about an hour of "warm up" before I listen critically. Put on a disc, hit "repeat" and come back after an hour or so for serious listening. I turn on my tube amps and preamp for at least 60-90 minutes before I bias and start listening. Overall, everything needs to be running for at least an hour or two before the equipment "settles in". Amazingly, even the quality of my electricity will vary and effect the sound. I bet a lot of us here notice for some inexplicable reason, some days of listening are better than others. I attribute it to the oddities of supplied electricty. However, I noticed I have consistently more satisfying listening sessions since I put in a PS Audio Power Regenerator. Long and short, warm up the gear before you get too critical.

I think that Marakanetz may be correct.

I went from a Spectron Musician III Mk 2 to a Pass XA 30.5 and had the same thing happen to me, at quiet, simple passages it was great, but at loud or more complex passages everything went mushy.

I was told that it was the lack of power with the Pass causing the problem. I returned to the Spectron and everything was fine again.

Call Glenn Poors in Champaingn IL..he is a Dyn dealer and part owner of BAT..he can get to the truth for you.
