Vandersteen 2WQ Subs and ARC Power amp
The crossovers are X-2B, fixed values no batteries. 
Vandersteen 2WQ Subs and ARC Power amp
Another piece of info, there seems to be little difference in output level with or without the crossovers. 
Vandersteen 2WQ Subs and ARC Power amp
I do hear a thump.  And if I disconnect the main speakers and just listen to the subs, I do have very low level output.  This is beyond subtle though, all the way to nearly dead.  Unless I just need to get used to these....

Pass labs xa25 amp and BW 804 d3?
I use Rockport Mira's, with similar sensitivity to the B&W's, could I conclude that the consensus here is the XA25 might be a good fit for these as well? 
ARC REF 150 Buzzing noise
Update on the sad story of my Reference 150.  Took it to Audio Tube Supplies in Denver, they determined that one of the input tubes was out of spec, causing one of the KT150 tubes to become over-biased and over heat.  This in turn (educated guess)... 
ARC REF 150 Buzzing noise
Called Evan at Audio Research, seemed very knowledgeable.  He thought the problem was a transformer, the good news is there is a service center near me that can repair it.  I think my cost will be about $ 800 including labor if it turns out to be ... 
ARC REF 150 Buzzing noise
Update after last post, there is no time dependency.  No matter when I turn on the unit, it will start to buzz after about an hour.  Anyone know what those transformers cost? 
ARC REF 150 Buzzing noise
Moved the power cord to another circuit, quite close to the power panel.  The amp was quiet for about an hour, which got my hopes up, but then started the nasty buzzing again.  It MIGHT be one of the three transformers, but the exact source is har... 
ARC REF 150 Buzzing noise
The speakers are 89 dB.  Up to a few months ago, I didn't hear buzzing at all.  I did remove the amp from the Bryston BIT-20 and the buzzing didn't go away.  I will try turning off other circuits in house next.It takes an hour or so for the buzzin... 
ARC REF 150 Buzzing noise
Should have mentioned that the amplifier is plugged into a Bryston BIT-20 power unit, an isolation transformer.  I am in a new house, but only for a few weeks.  I am unsure if I heard the buzzing in the old place.  Perhaps so.  I will try plugging... 
Phono Preamplifier recommendations for matching with Dynavector Karat 17D2
elizabeth, have not seen any unicorns around here, but since you are using an ARC unit I could mention that at the moment, I am using an ARC PH-8 with my 17D2.  This gives good results.  I am not sure if the DP-75 would be comparable, better, not ... 
Phono Preamplifier recommendations for matching with Dynavector Karat 17D2
tomic601, when you have more time with the unit, please let me know what you think, in comparison to others you have heard, thanks. 
Phono Preamplifier recommendations for matching with Dynavector Karat 17D2
Thanks, i have looked at that one.  Will appreciate getting other opinions but the P75 is definitely on the list. 
Audio Research PH5 Phono Preamplifier Input Clipping Problem
Anybody have an opinion on the ARC Phono Reference Mark 1 that has just shown up on Audiogon?  Those gain numbers appear to be in the sweet spot for my A90 cartridge.
