Lack of depth problem


Can someone please give me suggestions on how I can improve the sound depth of my system? I recently upgraded my speakers to Focal JMLabs Alto Utopia, but they still lack of depth. They have wide and tall sound stage though.

The room is about 15' wide by 9' tall, and 23' long. The speakers are 5' from their rear wall and the seating area is 17' from that wall. The room is lightly treated with sound panels.

Thanks in advance.

Let me state my setup more and start with electronics first.

CD: ModWright Denon 3910 player with Bendix 6900s and Mullard Blackburn 5AR4
Preamp: BAT VK-3iX with Sixpak and Superpak upgrades
Power amp: Counterpoint NP100 hybrid power amp and voiced to SET amp sonics

The speakers are about 9' apart center-to-center, and 2 3/4' to the side walls (from center of each speaker).

One speaker has a big tall bookcase full of books behind it. The other speaker has a thick area rug hanging on the wall behind it and a bass trap panel on the corner behind that speaker.

One side of wall has a large area rug hanging on the wall and a sound panel hanging at the corner (of ceiling and side wall). The other side has three 3'X5' windows covered with wood blinds. It also has a sound panel hanging at the wall/ceiling corner. All sound panels are RealTraps.

The floor has thick carpet throughout. Chairs also have thick fabric.

I am starting to think the problem may be the 61" rear projection TV in the center of wall behind speakers. I have covered the screen with blanket though.

My previous speakers are Acoustic Zen Adagio and JAS Orsus. They both lacked depth too, in my setup at least.

The sound image is very good and crisp. Two of my audiophile friends came over and both observed the same things.

I went to their listening rooms in the past. Their setups have more depth than mine.

If the problem is indeed my TV, what can I do about it? Other than removing it... LOL....

Thanks all for the advices!
You need to invest in a quality amp that has a large overbuilt power supply in relationship to its output power. Speaker positioning can help but good depth has to be present to bring it out.
The speakers are about 9' apart center-to-center, and 2 3/4' to the side walls (from center of each speaker).

Can you move each speaker 1 foot in and place them 7 feet apart. It will not throw quite as wide soundstage but it will give you more depth.

Alternatively, as Bill suggests - try toeing them in quite heavily.
Shadorne that could be a very good alternative but personaly if I had to sacrafice soundstaging for depth, that would be unacceptable. By the way what I said about amps also applies to preamps. The argument for toeing in speakers is considered by many to be a bad move.
Vett93- You mention having your Counterpoint "voiced". Was it converted to 6SN7 drivers? If not: what 6922 type drivers do you have in it? Do you know anyone that would loan you a tubed amplifier for an audition?
