Ideas for used SS amp

If you are looking to sell one of your amps I am assuming you are vertical bi-amping the pair. I am surprised that you find the bass lacking, but I have never heard your speakers. I have Alon V MKII bi-amped. the speakers are not overly efficient. I changed from bi-amped Sim Audio ss to the cary v12r and have been very happey with the switch. I would advise keeping the second v12 and auditioning a ss amp before making the final decision.

The Carver zr1600 has variable gain to allow matching the Cary and can be bridged for massive power and shorter cables.

I'm not sure I would use something as good a the Pass just for bass, not if you might be going full range in the future the Pass is one of the better choices for high-powered SS -- do you need that much power to drive the VR5?

Krell FPB 300cx. I use it with VS VR5 HSE's and they are a perfect match. Musical and with tight deep bass in spades.

Maybe one the older Jeff Roland Design Group amps might work well for you;several have shown up used in the last few weeks

An Acoustat TNT200 is a wonderful bass amplifier. I had one driving a pair of RH Labs subs and it worked and sounded superb.

2nd the Hafler suggestion. ie:(http://cgi.ebay.com/HAFLER-9300-AMPLIFIER-AMP-1200-WATT-HOME-THEATER-MOVIE_W0QQitemZ230373733135QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item35a358330f&_trksid=p3286.c0.m14) The DH-500 will drive you up a wall with it's fan noise. Other than that; they're a potent bass amp. The TransNova 9300/9303 and 9500/9505 are all fast and testicular(with no fan) which makes them excellent woofer amps. You'll have to attentuate whatever you get to match the drive of the amps. A Synergistic Research AC Powermaster will make a world of difference with one of these, BTW.

I was planning on using the one V12 for the top end and a used SS for bottom,right now I'm using 2 V12's.

Clayton amps might be worth a look as well.
