Room correction in high-end system???


OK,lots of praise has been heaped on the Tact and Sigtech RCS systems, including in this months TAS. However, I believe my system is pretty high-end (at least by the "How much does your system retail for?" thread) and do not want to harm the already fine sonic charactersitics. I am generally of the mind that "less is more".

Things that concern me are:
- Putting an A/D and then D/A into my vinyl playback chain.
- Putting a lower quality D/A in place or in addition to my SF Processor 3.
- Replacing my beloved BAT VK-50SE pre with a one box DAC/ADC/RCS/PRE.

If my system were in the sub $40k retail range, I would be running to a room correction system, but am a little sceptical given my current investment. It might even be a little snobbishness. However, if I do like it better with RCS, I'd end up saving a bucket of dough.

Has anyone with a well set-up room and system tried one of these? I'd be expecially curious if Mr. Porter or some of the other vinyl fans have had one of these in their system.

Thanks,

Hey Metaphysics
The thing about a vinyl front end is that you have to run it through the units A to D, and that leaves you at the mercy of the quality of their A to D. It also seems sacreligious to convert a beautiful analog signal from a turntable.
I began this process with room treatments. I have ASC cube traps in the front corners, and ASC sound panels on the side and back walls. The cube traps helped but didn't come close to resolving the bass problems. They also put my wife over the edge, given their size.All of this helped a bit but in combination with the Accuphase, it really all came together.
Robert Greene has been writing about these units in Absolute Sound. The new issue compares the Tact, and the Sigtech, and if you go back a ways, the Accuphase is reviewed as well.

Metaphysics, I'm in pretty much the same boat as you. I'm hoping that at some point dCS will put the room correction capability into their Purcell (which I have) so I could see what it does to the digital side of my system without a large cash outlay and another box. However, I don't know how much I really want flat frequency response in my vinyl playback, or any playback, for that matter (I too would not like to bypass my beloved JP80). Green of TAS seems to think that the improvements of flat frequency response far outweigh the additional wire/circuits/digitalization of an analog signal; I'm not so sure. Plus, it could upset the balance of the system which could require new cables, etc., which I have chosen based on how they work in my system and room without the correction. I guess really the only way to find out for sure is to get a dealer to lend you a unit which would be compared on the digital side of the system, that way you could hear for yourself whether you really want the improvements. Given my listening biases, I probably won't want to do it, unless the logical side of my brain takes over.
SACD is also an issue here. You would have to either bypass the DSP or do A-D on the SACD, which I think would reduce its advantages over 16/44.
Rcprince, regarding the balance of the system, my understanding is that you would correct for desired frequency response on the system as a whole, as it is. So you wouldn't need or want to change cables necessarily. Though I suppose how and why we choose the cables we do could be altered dramatically with room correction in the picture.

Also, I'm not sure flat response is the goal here. The folks at TacT seem to feel that a truly flat response would not be enjoyable. The idea is to get rid of the big variations. I have not seen the latest TAS yet, maybe REG has a different perspective.

I own a Sigtech and currently use it with dCS Elgar and 972 units direct into customized Melos 400watt monoblocks driving Dunlavy SC-Vs. If you are addicted to a pure analog vinyl sound you should not use the current generation of DSP. ASC room treatment is the only really high end alternative. Neither TACT or Sigtech will have units that have sample rates of 96 or 192 in the forseeable future. So using the new dCS A to D will not work since you won't be able to use the higher sample rates. If you are primarily digital, the Sigtech is an excellent addition no matter what the cost of your system in and has no audible negative artifacts.

Very few people spend enough time or effort on good room layout and treatment (physical or DSP). If your system is north of $40K you sure aren't hearing your money's worth without it.
