AK,

I have had this tube preamp for years. I use Mullard 7DJ8 tubes in this modified unit. I use a audio swigtch box so I can use both the 1070 for surround and the tube unit for Cds.

I just sold my former Anthem AVM-30 which was awesome for surround yet terrible for music.

The 1070 when I used the multi-channel DVD input in Bypass mode (analog) and the switch in the back set for HF/LF so the sub works in analog mode, the SQ is good.

These days all new HT stuff have terrible preamps so mucis is lousy yet the 1070 is decent.

My Tube preamp is really great and it is a dedicated premap and i use mullard tubes.

The SQ is Fuller, more detailed, open and more 3D.

Hope this helps?
