Wyred. Totally wyred or can pair with Cary SLP 98

hah I don't think you're driving the right direction. tube amps go for optimal sound(technically stable offset) much faster than solid states. Digital solid states need larger wormup time than conventional A/AB, B etc...

The ST500 sounds great with both my VAC Renaissance and Manley Shrimp preamps. This is with N802's. The ESP speakers are designed for a tube amps. In this case the VAC PA100 is better than the ST500. When I use the ST500 it is powered on all time (sleep mode) it awakes when a signal is present.

I recall the Sonatina's as being a good match for tube amps (non reactive and high stable impedance) so you may lose some of the tube magic. If you were attempting to drive a more challenging speaker, I would recommend you try a Wyred amp.

IME it takes maybe 10-15 min for my tube gear (VAC, Cary, Manley) to hit its stride. So, I wonder why you find it takes 15-30 mi longer for your system? I agree with Marakanetz that solid state will take longer to warmup, and even so may never equal or better what you already own.

I have the Cary SLP98P and I'm currently running a Cary CAD 120's w/ Cardas caps. I had a V12I and V12R also. I used to run a McIntosh 7270 SS amp that I loved and a Carver 1.5t SS amp. I wouldn't go SS with an amp if I had your Cary. Your system won't sound as good as what you already have unless you get a better tube amp, and Manleys are good. It may be better to wait. Best of luck, and happy listening. BTW, you should be able to use the Cary in standby 24/7 although I never do.

I think Bbybaudio wants an amp he can leave on 24/7.
