calling all headphone gurus


I need to add "privacy" to my hifi experience in order to not disturb others around me.

I understand I can accomplish this in at least a few ways I already know about (CD player and/or amp with built-in phone jack). But, none of my current pieces have this capability. So, what do I need to do? Can an outboard headphone amp be "added" to my integrated amp and /or pre/amp combo, or do I need to sell my current amplification gear and swap out for an amp that has a phones jack? The CD player I use is not subject to change which is why I isolate the amps as the items subject to sale.

When answering, please let me know about the "how" to acccomplish this as well as the products that may be good.

I use Fi pre/amps, Exposure integrated and Ayre CD. Thanx, folks.

If you put a headphone amp into the tape monitor circuit, you can accomplish this, OR another option would be a Cary 300 sei integrated that has a headphone jack driven off of the 300bs, and speakers can be switched in and out with push of a button. It is considered one of the best headphone amps ever and it ain't bad for driving high eff speakers either.
As an avid headphone listener and previous owner of 2 integrateds...I whole heartedly agree with Peter S...the best idea is a Tape Out or Record Out. But, if neither exists try a Y fitting out of your CD player. Audioquest and others make Y fittings or your cable company probably makes a Y adapter. One will go to your Integrated and the other to your Headphone Amp.
I have not personally tried this unit, but it looks interesting. Maybe someone else here has tried it and could offer an opinion on the Antique Sound Lab UHC Signature:

The only disadvantage I see is the extra circuitry involved, however I am happy with my ASL headphone amplifier. Some have mentioned occasional quality control issues, but this is as simple and inexpensive as it gets.

Good luck!
