| BFP wrote on Sun, 23 February 2014 15:27 | That's a nice looking setup. It looks like a Crown XLS amp in your equipment stand. I'm looking at one of those,the 2000, for a sub amp. How do you like it?
I just finished Pi 3's and am very happy with the sound.

Thanks. I'm temporarily using the Crown XLS-2500 to power the subs, and the Yamaha RX-A830 receiver to power the mains.
I have to set the gain near max on the Crown because of low output voltage on the analog outs on the Yamaha.
That being said; the Crown is easily powerful enough to shake the house apart while sounding very clear and precise. I knew about the analog voltage from reading on other forums --, it isn't really a problem for me, but can apparently be with certain receivers, so be aware. Pro Audio pre's usually give an extra volt or so.
I'll soon be replacing the amps I'm using with some vintage Phase Linear D-500s, leaving the Crown out of my setup -- but that has nothing to do with the Crown and was simply the ultimate goal to begin with.

I'm running into some issues with my Phase Linear amps, and it'll be a while before they're up and running. I'm going to end up having some custom PCBs made up to replace the original ones that are damaged in both amps, and going in with all new resistors, diodes, opamps, and caps. I'll be upgrading the opamps while I'm at it.
In the mean time, I ordered a Crown XLS-1500 tonight to drive my Pi 4s, along with two Art CleanBox Pro's and XLR cables to put between the CleanBox's and the two Crown amps. The CleanBox's will be used to correct the gain issues mentioned in the last post. I've read great things about them on other forums.
In the last week, I also cleaned up my Sansui XR-Q7 turntable and replaced the cart with a Denon DL-110 and built a Bugle 2 phono preamp w/ 1k loading and 50dB gain. It works and sounds great.
