In Reply to: RE: Processor nightmare.... posted by ABliss on February 01, 2010 at 07:50:44
I have two Denon AVRs going here and set one up for a friend and they do a very good job. From what I read, Onkyo are maybe even better.
It all depends how obsessive you want to be as to how well an AVR would satisfy you. The ultimate AVR is reputed to be the (rather expensive) Arcam AVR600 but even it would have deficiencies in Blu Ray Audio due to the high jitter generated (nanoseconds rather than picoseconds) in the HDMI link. An S/PDIF link would bypass that but might not get the full benefit of BD audio.
The AVRs process both audio and video and certainly make connectons less hassle free although setting them up optimally can be challenging.
And another downside of AVRs not often discussed is the heat they generate. This drove me nuttier than usual when setting up my friend's Denon as he had inadequate ventillation. The heat caused loss of settings and this problem was not solved until he placed it on top of a cupboard rather than in a shelf. If my setup here I have a bathroom fan with speed control blowing air across the AVR. Works fine although computer fans on top of the AVR would have been less expensive. Not sure they would have been as effective as the present fan expells the hot air right out into the room wheras computer fans would only move it vertically.
Apologies if I've gone OT.

Agree about the heat. My Denon AVR which I only use as a pre-pro (i.e. don't use the amps) is by far the hottest component in my system. It has adequate ventilation. It always feels much hotter than a 60" Pio plasma and 7 channels of outboard amps.
Onkyo sells their better AVRs without the amp sections as pre-pros, pretty much identical for that use. Some of their AVRs get incredibly hot.
Now, heat may be a bad thing as far as longevity. But, and I don't want to go even more OT, but a lot of SS gear sounds better to me the hotter it is...
I've had problems with my iScan VP50 PRO video processor because of heat and will have to put 2 quiet computer fans on top.
Also running very hot here are video recorders with hard drives for recording. Unfortunately the trend for sexy low profile cases mean ventillation is often not good with fans omitted to save money. I find it necessary to put feet underneath to increase natural circulation and more computer fans are most likely needed also.
Not sure all this heat is good for video items, particularly those with computer hard drives inside, but I understand your point about audio.
Yes it is a bit OT but still relevant and could be a reason for ABliss's processor difficulties.

Thanks for the tip, I never thought of a heat problem. I do have it elevated in a open rack, but maybe a fan would help.
AB.
My items are on open shelves also, but the heat some generate is too much for natural ventillation to handle.
Worth a shot at trying in your case anyway.
