Yeah I'm basically sold on the Trinnov. Everything keeps leading me back to it. The 16 channel non expandable version, you can still upgrade HDMI boards and such right? Only part that can't be changed is the amount of channels?
Correct AFAIK but best talk to them or your dealer. I am not sure what other differences there may be, if any. I actually have an SDP-75 (JBL Synthesis version of the Altitude 32) as I was able to get a really great deal and it includes the PEQ for my Revel speakers. My dealer carries JBL, Revel, and Trinnov so was able to help with the pros and cons among processors with my speaker line-up. I have not implemented SFM yet (for the subs); really want to, but awaiting a SW update that is supposed to help with that (it requires external help now). Dealer , JBL, and Trinnov support has been great. The flexibility and control is amazing and I have only scratched the surface yet. Trinnov has a bunch of online videos and tutorials that are very useful.
Toyed with the idea but never expected to fork out the $$$. Frustration with my then-current (Emotiva XMC-1) processor and their struggles rolling out their new model (XMC-2/RMC-1) gave me significant pause, and when a few refurbs popped up at significant savings I made the jump. Funny, both my dealer and I bought one, then let them sit for almost six months, then we both set ours up within a week or two of each other. There are some glitches, and I had to rig up a remote on/off solution (see the Trinnov thread on ASR), but it is head and shoulders above the other processors and AVRs I have had (Denon, Emotiva, Pioneer, Sony, Yamaha).
I had planned to add high speakers for Atmos a couple of months ago but got derailed by Life and Work. I have a plan, just waiting for things to settle down a bit and to get some free time and funds to implement it.
