You can always do some kind of tube stage before the amp. I have found a high gain preamp works best on my 1500s. Which allows a lower gain setting on the Crowns that reduces the bit of hiss you may get from them. I'm at 12 o'clock on the amps, hiss is inaudible > 6" from speakers.They are said to need at least 200 hours break-in, maybe more. Try using some sort of vibration isolation under them, I use a homegrown recipe of cedar pucks, sticky cork, and Sorbothane Half Hemispheres under mine (see above). If you want to really get tweaky, try mass loading the tops. If you don't like the blue display blaring out at ya, cover it with a 1-5/8" piece of electric tape.
If you do decide to keep the amp, replace the stock binding posts with Pomonas 3770-0/2, it is an easy bolt on replacement and reversible for warranty reasons.
Leave the amp on 24 / 7. It pulls very little current on standby so no biggie. The amps supposedly benefit from a power cord upgrade, I haven't gone there yet.

I read that the XLS Drivecores to go after were the XLS2000 and XLS2500. I have the XLS2000 and like it (only heard it on my Acoustat ESLs so far) -- just need more time to decide if it really is a keeper, and gets Pole Position in the in my main system...currently "owned" by my ICEPower 1000ASP based DIY amps.

The XLS1000 model has a worst SNR. The 1500, 2000, and 2500 have the same better SNR. AFAIK, that and wattage is the only differences. Thinking the 2000 and 2500 may be in a bigger chassis?
