BAT or other Valve pre for PASS X-250

Hi there,
Wondered if anyone had tried using a BAT pre (Vk 3/5i)with any of the X series PASS.From my reading I understand there may be a mismatch due to the BATs (already high)impedance rising at low frequencies whilst the Pass has a fairly low input impedance.
I need a balanced valve pre to go with the X-250.
There are noise problems with the unbalanced input, I may need to drive long interconnects, I can't live without at least remote volume and definitely need valves as the Pass is way to solid state sounding for my tastes with a ss pre.
Changing the power amp is not an option at the moment.
Thanks in advance,
Simon

Hi
I use my Pass X250 with Cary SLP 308.Perfect.All the wiring are Straightwire Crescendo .Speaker cables:Kimber Bifocal Xl.I've found that X series like bright sounding speaker cables.Look for a cable matchup first.Take care.

Simon74,my amp does make a faint buzzing sound too,not thru the speakers though.I guess 86 db sensitivity plays a role in that too.the buzz is audible from a couple of meters.
but as far as the sound goes,mine sounds on the par with the old CJ designs:tubey and lush.I had a mismatch with speaker cables before,the sucker completely made it unlistenable with my beloved Straight wire Crescendo cables.
It took me some time to find a friendly cable and once i connected Kimber bifocal XL,everything came together.
