I'm sure mkbruce will respond, but I will as well. I've had my Sigma SSP for a couple months now (as well as the Sigma AMP5) and couldn't be happier. I started out with 2 channel using a Classe CAP-2100 integrated driving my B&W 805Diamonds, but really wanted to expand into surround sound for movies. It was important that I not sacrifice 2 channel music, and I pretty quickly ruled out all of the surround processors and receivers I looked at (including Arcam, NAD and Marantz). I first heard an early Sigma SSP pre-release model at a Music Matters event in Seattle in Feb, 2014 and was eagerly waiting its final release. My local dealer finally got the Sigma in late November of 2014. As I mentioned earlier in this thread I brought in my CAP-2100 for a direct comparison with the Sigma for 2 channel, and the Sigma pretty easily won me over.
(As an aside, my dealer also got in the new NAD Masters series pre-pro, but I'm averse to an all digital signal path. I feel that digital is still evolving too much to lock in that firmly. As an example, I only just read about the new MQA technology from Meridian last week. But if your processor converts everything into a PWM stream anyway you can't really adopt a new technology. I know NAD has their modular construction, but it seems to take them a long time to come out with upgrade modules)
About 2 weeks ago I decided to take the plunge and get back into vinyl - after having sold off my collection back in the 90s. I ordered the phono stage for the Sigma SSP as well as a Rega RP6 turntable, and I'm in audio bliss the last couple of weeks as I slowly build up my collection. I'm still a novice as far as turntables, cartridges and phono stages go, but I feel that Classe has done an awesome job with their phono card (my dealer told me it's the same card as the one for the CP-800). To be perfectly honest, I'm not sure I'd say that vinyl sounds better than digital through the Sigma, but there certainly is something about the ritual of putting the record on the 'table and lowering the needle.
One issue I was having is that the Sigma was not outputting a signal to my subwoofer in analog mode (my 805s need a little help on the bottom end). Took my salesman about a week to track down the issue with Classe, and the latest firmware beta fixed the problem. I also installed the firmware update that came out earlier, and I've had no stability issues at all.
Oh, and mkbruce - the ios app does take a while to pick up the input changes. What I discovered is you have to completely shut down the processor and power it back up for the app to see the changes. Just putting it in standby won't do it.
