Depth of sound stage--I need help

Are you primarily concerned with the depth of the sound stage or pinpoint imaging? They are very different concerns.
I own a large Krell setup driving the biggest B&W's. My imaging is "to die for", yet my soundstage is often not particularly deep. That tends to be the way Krell reproduces the soundstage.
I go frequently to the symphony, sit in the 10th row center, and I can tell you that most of the time the soundstage is NOT deep. ... And that is in real life! Some equipment overdo the depth "thing", which although impressive, is not necessarily reality.
I hope you find what you are looking for.

To the above I can add that J. Gerhard (Mr. A-P) likes near-field listening. Immedia has a presentation on speaker placement that U may want to consult. Regarding A-P I have found that the more the horsepower provided the bigger the "8" imaging and the further back it reaches -- hence, enhancing 3dimensionality. After playing with placement, I suggest you borrow another pre, and note the differences. Then, try a different cdp with yr pre and with the other one -- and note the differences. You may be able to identify the piece of equip that needs to be changed for yr tastes. If nothing works, you're left with the amps... which would surprise me.

Excuse the vagueness, I just can't combine yr equipment sonically in my mind at the moment -- esp. the 2.5 with the Quicksilvers -- to come up with something specific.

Good luck!

It has to be proportion to the preceive width of the soundstage. If the width is about 15ft. Then the depth should be about approv. 1/3 of the width and it all depend on the recording.

I've been thinking bout this soundstage thing for a while now and depending on what is being listened to the depth part of it can be one big illusion. As indicated above the illusion can be helped by speaker placement but i think that walk around the dude feeling is very recording dependant even with a killer rig. If you are listening to classical or a small jazz band with the whole stage miked by a few overhead condenser mikes the depth thing is the real deal reflecting the time required for the sound to reach the mike from different parts of the stage. Likewise if you are listening to a recording where everyone played live and there was bleed through into the vocal mike up front or maybe, but not likely, into adjacent instrument mikes there may be some real depth. The truth is that for a lot of recordings a SM-57 or equivalent gets shoved in front of the amplifier or drum in a close mike arangement where every instrument is isolated in it's own channel. Ain't no depth to be found there. That being said as Drrdiamond pointed out for classical there isn't all that much depth i can back that up for almost any amplified instrument show i've ever attended.
