    [QUOTE=vivaregina;320627]. Any other pre amp suggestions?
    /QUOTE]

    Mark Levinson No. 326S. And if you can swing it, an ML 331 or 334 for the high pass power amp. Brystons are great, I use them for sub duty and band pass, but an older ML for the highs is sublime when combined with the 326S.

    Went to a demo session with Jerry Rig to visit some field coils. Jerry knows his stuff. Great guy. After talking with him, I might get around to plugging some more tubes into my line up and see what happens.

    From Nelson Pass ...

    Later versions of the XVR1 have an added internal switch which places the high-pass filter after the low-pass filter. The low-pass output on the rear panel is untouched, but the high-pass output reflects both the low-pass and-high pass filters. This is simply a convenience feature – you can get the same performance with the original circuit - in both cases it requires 2 XVR1’s to make a 3 way crossover.

    Right, thats the BP jumper we mentioned. Aside from convenience, it allows one complete filter to be made from a single box as opposed to having the filter spit between two different boxes with the additional wiring involved.

    You said you didn't notice any difference between the 2 different methods, and others have commented that they prefer the BP configuration as opposed to the daisy chain configuration. So it's just a personal decision. I didn't know of it until I called and spoke at some length with Kent at Pass, he said that the XVR1 was one of the lowest noise devices they made and daisy chaining the units as in the manual shouldn't be an issue...but then they still added the BP jumper, which meant a change to the circuit boards. There must have been some perceived benefit, other than convenience, to go through all that.

    You evidently got a lot more out of his post than I did.

    Strangely, they all have their strengths. Each time I switched over, I noticed and preferred the switch. In a strange way, I hear what was slightly lacking previously. BP26 has better bass resolution, 7 has better highs, JP80MC has better tone and sound stage. If I were forced to live with only one, I might choose the latter, the most musical. But in the end, the answer is enjoyment found in all of them.

    The Marantz was actually switched on., but I made the photo too small so you had to squint.

    Ah, I also tried the least dynamic ... it was a passive 50K volume pot.

    One more pre amp coming ... I hope this week.... a 3 piece.

    You should crop your pic just a little more, we can still make out what it is.
