How to improve 2-channel performance in HT rig?


Hi all . . ..

I just "finished" upgrading my HT system, and I'm pretty happy with the way it sounds for movies. However, a funny thing happened during the upgrade -- my 2-channel performance actually became good enough to be enjoyable. I had planned on using the system for purely home theater, and using my headphone system (ASL MG Head OTL, Music Hall CD-25, and Senn 600's) to listen to music. However, I find that I now enjoy the home theater system more than the headphone system, so now the inevitable "I want to enjoy it MORE" kicks in, so . . . .

Sony DVPS-9000ES DVD/CD/SACD
Lexicon DC-1 pre/pro
Rotel RB981 (130w x 2)
NHT 2.3A floorstanders
NHT SW2P subwoofer/amp combo
Signal Cable Analog One interconnects
Signal Cable Speaker Cable
Monster Cable HTS-2500 MKII power conditioner (Rotel is plugged directly into the wall, tho)

Plus six other NHT speakers and a Rotel 985 that aren't used for 2-channel playback.

What would be the best next upgrade to make? My suspicion, based on comments I've heard, is that I need to get the Lexicon out of the 2-channel signal path and replace it with a really nice, musical 2-channel preamp with a HT passthrough. But there are other possibilities -- add an outboard DAC, for example, or upgrade the amp driving the main speakers, or upgrade the main speakers, for that matter . . . . Aagggh! ;-0)

Eventually, I'd like to do all those things, but an upgrade of many thousands of dollars starts with a single step, so . . . .

I'm pretty happy with the soundstaging now (speakers are set up about 8' apart with about 3' to the side walls for each, about 4' to the rear wall and about 8' from the listening position, and about a foot out in front of the 51" TV), but I think the imaging could be improved, and I'd really like more richness, liquidity, and body to female vocals (Eva Cassidy, for example). The vocals and instruments have a presence, now, but still sound more "recorded" than "real."

(Of course, they ARE recorded, but what is audiophilia if not tilting at sonic reproduction windmills? ;-0) )

Any suggestions greatly appreciated!

Pat have you tried using any temporary acoustic absorbers over your RPTV? That big reflective surface only a foot behind the plane of your mains has a rather major effect. You might do a simple experiment of covering with thick layers of blankets. Not perfect, but I bet you'll notice an immediate difference. If that helps, you could always make or buy something that could be put in place when doing stereo.
No, I haven't tried anything like that. Seems like a good idea, though . . . . I ahould cover all the surfaces of the TV, right?

If it works, I'd imagine that a simple four-walled frame could be put together pretty easily, even using something like eggcrate foam, and that could be folded flat when not in use and and then erected around the TV for serious 2-channel listening . . . .

Thanks for the tip! I'll give it a try and report back.

My situation is similar. I am using the NHT VT 2.4 with Rotel RMB-1095 and a Sony DVD player/CD recorder/player for a source, all through a Marantz receiver as the Pre-pro. Home Theater sounds awsome, 2 channel sounds bright most of the time. I think from the sound of the suggestions I am going to try a new CD player.
Carlabarla --

I just ordered a 2-channel passive preamp from Channel Islands to replace the Lexicon in the 2-channel signal path -- I'll let you know how that turns out.

You mentioned in your other post, though, that you were using an inexpensive Sony DVD player -- if that's the case, you will definitely want to upgrade that. Of the things I'm trying to "fix" in my system, brightness isn't really one of them -- but I'm using the Sony 9000ES, which The Absolute Sound ranked as competitive with any sub-$2000 player for Redbook CD playback.

I've been living with NHTs for a number of years, and they are merciless to inexpensive electronics. When I was using my Pioneer Elite CLD-59 as a CD player, I had to use a tube amp (Jolida SJ-202A) to make NHTs listenable, and even then some CDs still sounded unpleasant.

Another thought for you . . . . I don't know what the VT2.4s are like, but I know my 2.3As benefitted significantly from being raised up about 8 inches off the floor, so that the tweeters are level with my ears when seated. Doing that improved the soundstage depth, and made vocals recess slightly back into that increased soundstage so that they didn't sound "in your face" any more.
