Hi i am new to the AV forum's and i am the proud happy owner of my AV32Rsl since 2003 circa.
I have it in the following setup:
Arcam DV-27 FMJ
Rotel 1075mb 5.1 amp
SKY HD
B&W CDM7SE speaker's

I have decided to after all this time upgrade/enable the HDCD option as i have enough of these discs and some japanese 20K cd's also to use through it if these would also work?.
So my first question is, can i get the unlock code anywhere else (anyone from this forum?), or will i have to get it through IAG and pay around £50?
Secondly i cannot remember which version i have, wether it is the 192 or 96khz version as when i talked briefly to the sales help desk the other day he said if you have the 5.1 bypass then you have 192, but i am not so sure as i thought the front casing had a 192 stamped by the model info (bottom left hand corner) if this was the case? (mine does not)
My version also came with pro-logic II as standard if this helps.
Also if i do not have 192 is it worth upgrading to it?
And to further that is it worth upgrading to the AV32R DP version despite me only having a 5.1 surround system?
Just wandering if the TReq function works with 5.1 system at all? and if it really does make that much difference or benefit from having it in the setup. my room is currently 20 ft long and 15ft wide.
Plus if having 8x better sampling with the DP version will benifit the two channel for when listening to cd's?
Bearing in mind i am a big 2 channel music enthausiast.
Also is it worth upgrading the firmware from my current version 2.75 to the current 3.8? (as i do not know the improvement's and could not find the thread on here for change implimentation's)
Sorry for a long winded bunch of question's for my first post, but am basically wandering if it is worth upgrading to my AV32R to the next level (depending i can work out which version i have 96 or 192) or going up to the top DP version?
And is IAG the only/best place to get any upgrade's done or is there any reputable third parties that can do this?
Thank's....
