I am looking for a surround sound preamp. Anyone have any ideas?
Follow Ups:
the B&K 1030, which is from '98, but if you do not need DTS then it is still fine. Used sell for around $400, I think, maybe less. Was $2000 new and had fine build quality. I found this unit too bright though for stereo use, as I believe the standard cheap op amps are used to amplify the signal from input to output jacks.

Don't own it, but do have their ICBM... great product. (Using the built-in processor of a Sony DVD/SACD player and Sony TAP)
JK,How is the performance of the onboard DVD processor with the Sony TA-P9000ES preamp vs. using a dedicated SS processor? I'm thinking about doing this as well.
I don't need all the various SS options, just want to decode DD and DTS, but was wondering if I sacrafice much sound quality with using the DVD decoder.
This setup is my first Dolby Digital surround system...originally I was using a Sony TAE1000ES preamp with prologic, (and a bunch of DSP modes I never use) / mitz. VCR to play back the weekly blockhead movie rentals, was waiting for DVD rentals to become availible. Also was using a Sony ES cd player for audio. When the CD player started having problems, then was a good time to replace it with a DVD/CD player (Sony DVP-NC650V). Because of the current copycat crap, all hi-rez/DVD players come with built-in decoding with analog outputs. By adding the TAP, I could leave the current preamp in the system, using "5.1 bypass", and send the DVD signal to the "5.1 input1", and still add another 5.1 and 2.0 source for later.I can only assume that a high-end prepro would sound better, for more cost, but it seems like every time a new "surround format" is introduced, it will make that great prepro "obsolete". As is the case with so many things going on in the audio/video market right now. Damm my ass hurts from sitting on this fence!
Anyway...The Sony TAP is a geat product, very quiet (leave it on 24/7), and seems to be well built. This combo sounds fine to me, using Aragon/Thiels for mains and Marantz,NAD/Def.Techs for ctn/rears. Adding the ICBM (between the DVD and TAP) is mandatory if you don't have 5 full range speakers (who does?). One cavet I have is I found that by using the "recombine" funtion of the ICBM, which sends a full range signal to the mains, and a selected range (I'm using 80hz. on all channels) of the same main signal to the sub, gives the best bass responce the Thiels have every had. But running the mains bypassed out of the ICBM, for a slightly cleaner sound, and still feeding that ICBM sub signal, does't give me the same results. Go figure. The other caveat is you end up with lots of level controls, (5 for the bass signal!) lots of fun to set up.
That was a great response JK with very useful information! I'm not clear on the ICBM however. Why is it necessary?I would assume that normal stereo does not have bass management even when people are using LF bookshelf speakers. Don't speakers naturally cut off when the signal is below it's capabilities? Why is it a concern in this application?
I wonder if it's worth the added cost, not to mention another set of cables.
You're right to be concerned about the extra cost and cabling, but for me, it's worth it. The DVD/SACD player I'm using has two choices for speaker responce, full range or cutoff at 120 hz. While it's true that even a small bookshelf speaker can be fed a full range signal, the fact that it's bass responce is so limited means that a portion of the music/soundtrack is not heard. Being able to route that missing information to a well placed subwoofer makes a BIG difference. Also, using the factory cutoff setting of 120hz. is too high, IMHO, especially for the center channel speaker. The ICBM allows you to determine the lowest (but safe) bass level you can go for each speaker, then send the rest to the sub. Played the DVD "The Matrix" before installing my ICBM, the lack of bass material made the soundtrack high-pitched and ear piercing. After installation, much more involving, from all channels. Go to their web site, you can download the owner's manual, tells you everthing you need to know.
There are many surround pre-amps in all price ranges available. Look at audioreview.com to give you an idea of what's available.
if you want a used one go to audiogon.com or ebay
I found an inexpensive refurbished surround sound preamp/amp (with
lots of preamp outputs) on ubid, after following eBay and audiogon
for months. Might look there too.
