Soundstage...How to determine what's right?


Have started upgrading my system and will be trying to optimize the soundstage. A lot of reading has me thinking that I really don't have enough information and experience to get there.
Terms like "congestion, width, depth, and height" have me wondering how much is in the recording and how much is introduced by the system? Are there reference type cd's that people use to determine how their system is progressing? I so, could you help with a list of cuts with info regarding the placement of vocals, instruments and examples that contain material that is not congested?
Thanks for any help.

Hi Scoly1- Check out this URL(http://www.balanced.com/products/cd/Vk-D5/index.html) for an idea as far as a tubed CD player. It's what I've been using for a few years now. My previous one was a California Audio Labs Alpha/Delta CD player/DAC set-up. Either are still available on the used market(sometimes on this site, sometimes eBay) for considerably less than what's considered SOTA, but will still deliver all the music your system can process. The CAL pieces are no longer supported by anyone unfortunately(the only drawback), though I did find a shop in NY that had replacement LASER transports. Both lend themselves to the adventure of tube-tasting. BAT has a newer VK-D5 iteration that is more costly and is restricted to the tube created by the company. Happy listening!!
One more thing: Be certain to read the reviews on the VK-D5. Especially the comments on soundstage reproduction! Enjoy!
Your description on tube miking in order to add harmonics brought up questions. Does the same type effect occur with amplification, processing, etc.? Is this why so many people feel that tubed components sound so much better? It would be very difficult for me to go tubes in my pre and amplifiers due to using them both for 2 channel and h/t. Would there be a significant improvement in 2 channel using a tubed cd player? Funds don't allow the ultra hi end but would like to get a bit closer.

Yes and No. I will try to stay away from any argument about which is better. Both are good when used CORRECTLY. Good tube designs can sound pretty much identical to good solid state designs when driven below clipping...at the end of the day it boils down to the way the circuits are implemented and how they are coupled (high impedance ouput transformers often used with tubes will certainly modify the frequency response, for example - is that good or bad - your choice!).

One of the world's top Mastering Engineers, Doug Sax, and founder of Sheffield Labs still uses tubes in his mastering console (built by his brother) - so yes tubes can be used to modify the sound in line level equipment too (and very nicely in a CD player, for example). The main advantage of tubes is that they sound nice when clipping...solid state sounds terrible...and as my drum link above illustrates ...clipping is all to common....even the pop CD's you buy today often have lots of clipped signal on the CD!!! Tubes make a lot of sense for live music or recording live music if you are not sure what levels you may drive the equipment too - like an electric guitar, where musicians always crank it and tubes just sound wonderful when cranked!

The VK looks like something for me to dream about. It'll be a while befor I am able to justify something like that. Do appreciate the link. Good reading.

Once again thanks. The idea of a tubed cd player is an interesting one. Just wish someone I knew had one that I could try in my system. At this time it is just an interesting idea for me but sometimes I fall prey to impulse buying.
Thanks again,
Steve
hey Scoly1- If you're still in here, check this out: (http://www.upscaleaudio.com/view_category.asp?cat=50) You may be able to pick one of these up used and upgrade it when the funds become available. It would give you a taste of what a tubed source can do for your listening. There are a number of upgrades available. The first thing I would do would be to find a matched pair of Siemens E188cc's to pop in there. That's if I didn't have the money for those wonderful 1960's Siemens CCa's I'm always raving about. Read the Stereophile review(if not all of them).
