Should I upgrade home theatre to one with HDMI?

Just wanted to emphasize a point of clarification for anyone not completely up to speed on this format and connection stuff.. ....
Any of the TV, Cable, Fios or Sat boxes will not use the high resolution uncompressed audio that you hear about. (They cleverly make little mention of these specs in the cable marketing and high res audio won't be happening anytime soon) So, the hdmi cable input avail is just an issue of wiring convenience for audio (and a flim flam excuse to sell you new gear) .... The old fashion fiber or coax cable is all you need for Dolby digital 5.1 TV as many of the posters recommend.

Now.... the high res audio formats on Blue Ray discs are fantastic sounding and a good reason to spin discs and hook up the gear with hdmi or 7 channels of analog cables (pick your favorite Dac/pre amp and room management technique configuration)

Admnranger have you chosen the DACS of the Oppo over the Room management and DACS of your Rotel by ear?

"Admnranger have you chosen the DACS of the Oppo over the Room management and DACS of your Rotel by ear?"

No I have not. My Rotel doesn't handle the new codecs on the blu-rays so I let the Oppo do the heavy lifting.

For cd's, I let the Sabre chipset in the Oppo again do all the work. I can't image that the 2005? era DACs in the Rotel receiver are going to trump the ones in the BDP-95 Oppo, but I could be wrong. Are you suggesting that they are better or will sound better with my setup, Tcatman?

I let the Rotel handle the processing for the ipod output coming out of my Wadia i170 and the DirecTV HD DVR. Otherwise, the Oppo does the DAC work for me.

Actually,

I was looking for your opinion on the tradeoff between room management through dsp with your Rotel.... VERSUS the "potentially" better sounding DACs of your OPPO.

Another way of framing the question... what's most significant as you evaluate your upgrade path..?

Room management, Base management, better DACS, No jitter, High Resolution Formats AND what is the rank order for two channel versus 5/7 channel music content..

Everyone has their bias...

Tcatman: Sorry, I may still not understand, but I'll give it a shot.

I don't like what the Rotel does taking 2-channel input and running it through it's DSP for 5.1 sound. If I didn't have small front speakers, I'd run 2 channel bypass but I have to add in the .1 as my speakers roll off once you are in the 60-ish hertz range.

My room is definitely not optimized nor will it be barring personal tragedy or divorce (for me it is one in the same). The Rotel room management doesn't exist. I don't have any automatic room management/sound correcting software working (maybe I'm misunderstanding what you are getting at).

Bass management is done by ear. I've now had my subs in 3 different spots in the past month. I think I'm getting close to liking where they are.

I don't have any SACDs. So high resolution formats are HDCDs and blu-ray concert dvds. I don't even like some of the DTS audio cds I have (Henley's "End of the Innocence" for instance). They are muddy and meh to me. I prefer the regular CD hands down in this particular instance. Adele at Royal Albert Hall blu-ray, in stark contrast, is stunning in DTS 5.1.

Ah... I read through your other thread about your acoustic problems... Its a fun challenge!

Im not a pro at this stuff either... Part of my confusion was your terminology.
Bass management usually means the processing in the digital domain (either the Oppo prior to the output of your 5.1 analog signals.. or the Rotel (processing the hdmi input signal). The bass management had two jobs... One, to cross over the bass information to your sub. Two, process LFE or .1 channel and manage the gain issue for the LFE channel.

The old school method of using an analog filter in your sub with your two channel full spectrum analog signals coming to the subs and then high pass info to the mains was rarely termed base management. The subwoofer was never called... .1 because there was no separate LFE channel... The subs just played the low pass analog signal they got based on your filter cutoff while your mains were easier to drive without the bass frequencies.

So, I understand your current configuration as one of setting up the Oppo to do bass management for your 5.1 channel content using the single multichannel DAC in the OPPO. Sending discrete analog channels to the Rotel for all of your speakers and subs including the LFE info and the frequency information is right for each channel/speaker. This analog info is passed through the rotel and then amplified.

What I don't understand is how you manage the bass using your 2 channel (dual sabre DACS) outputs going pure direct to your Rotel amps for Music CDs ... It seems to me that you have to go old school with one of your subs running in analog mode because your not happy with the low end of your mains in stereo. (The other sub would be driven by the LFE channel in your 5.1 setup. (I can't imagine the Oppo giving you a third discrete output channel in this mode.) But I could be wrong about what your gear will do.

My original question is not applicable.
You don't have the ability to do room correction in the digital domain in either the Rotel or the Oppo and compare all of the potential solutions.

I am surprised that the Rotel is flexible enough to pass the 5.1 analog blue ray through to the amp AND have the CD inputs also bypass the digital stage and go pure direct to the amps.

So... I understand that you are at step one... Optimize the acoustics of your current speakers and subs in 5.1 mode. You are now trying to manage the acoustics of your room with a major WAF constraint..

Step two. You will consider different speakers given the size of the room you have and WAF.

In parallel with your acoustic experiments... you might consider a PC and JRiver MC with an HDMI output to your Rotel. (splitter for the video hdmi to your TV) You could use the DSP and room management tools of JRiver on the high resolution uncompressed 7.1 formats stored on disk and go to the Rotel DACS. This would allow you to evaluate if more digital processing room correction would improve your already optimized acoustics. (You would not have to purchase a new AV receiver to try the room management solutions)
