best amp for BASS

Try the Crown K-2, maybe two K2's in bridged mode. Although it's cheap I expect that it will outperform a Krell 600 or 650.
I use a Crown K-2 for my Wilson Audio WHOW sub which complements my Watt/Puppy 5.1. It has fantastic control and power. As the WHOW is a mono sub I use the K2 in bridged mode. It has 1600 Watt @ 8 ohms (2500Watt@4Ohms). Damping factor is above 3000!
List price of a Crown K2 is about 1800$ only.
Use XLR connections with the K2 if possible!

Geez,I'd love to have a Krell for Mains let alone for using one just as a Bass Amp.

I always thought Bass was the easiest single driver to drive provided you have a high Watt capability along with good Damping Charctheristics.

Just thought Krell might be alittle of overkill for a Bass amp.

How about an older MUSE or as someone aluded to the McCormick's. Anyways,just thinking!

His speakers are 4 ohm rated, the specs. call out a minimum of 350 watts a channel and bass output is rated 110db at 18HZ.

Thanks for the inputs.I do use balanced connectors.The bass is very clean not boomey but not powerful.My guess is that having a large room with very few walls(the size was describing floor not the enclosing walls) will require lots of current with fast rise time,and large power supplies.I agree the best approach is auditioning different amps.However this is difficult if you do not want to pay retail and you are buying on audiogon.I did hear the Loreley speaker with Crown amps,definitly inferior to Bryston.I do not like the Krell amps for their highs and mids,but maybe for the bass they will be good what about the FBA600c?
Thanks for the responses.

As mentioned, the sound that you hear will be most influenced by speaker placement and room acoustics. Given the level of gear that you have, i would hope that you've spent some time working with those two subjects prior to investing anything further.

Having said that, look for an amp that has an "old school" iron core transformer ( no toroids ), has "gobs" of filter capacitance and uses what most would consider to be a huge output inductor. Since effective damping factor can be increased by manipulating negative feedback levels, it should be high but you don't have to go crazy with that spec. One can't obtain ultra high damping factors without playing games with figures and circuit designs. My experience is that amps that work fabulously for bass are not necessarily amps that you would want to run full range and vice-versa. Sean
