Two different amps to horizontal bi amp?

I have Hales Designer Reference One speakers. They have three sets of post for speaker wire. I presently have one amp (Wingate 2000)class a amp. I have added a Sunfire signiture subwoofer to extend the lower registers but do not like the overall blending of the two. Here is my question / statement. I have an opportunity to purchase a Threshold S500 class a/b amp. I would use this to drive the woofers and use the Wingate to run the tweeter and mids. I feel the Threshold would elevate the bass performance and allow me to eliminate the sub woofer. Would this work? What kind of potential problems would or could I have?

Thanks

Dr. Sean,

I'm curious as well, Is it better to have two mono block amp, two identical stereo amp that horizontally bi-amp , OR using the the
same two stereo amp in bridge mode? Thanks for your help on
this Doc.

I have 2 NAD S200 running in Horizontal bi-amp mode driving
the Sony SSM9ED and is thinking of upgrading to the pass lab
x350 or the x600 mono block someday, but I still need to learn alot about high end audio before I can spend my money wisely. I'm a new baby to the high end stuff.

I personally think THE ONLY THING TO CONSIDER FOR YOUR BASS AMP is the Parasound stuff!!!! Not only are those amps RENOUNED for their dynamite bass impact,speed, and weight, but they are great value, and HAVE GAIN CONTROLS ON THE BACK FOR LEVEL MATCHING!!!...something your other amps won't! why spend bigger bucks on a higher end amp that will not surpass what the very flexible, well built, super strong bass performing, excellently priced PARASOUND'S will do!?!
I was using the Threshold T200(better amp) for a long time, and it was excellent! However for a BASS amplifier, I don't see using ANY OTHER AMP on the bass woofer than the Parasound! They're dynamite for that!
Anything from the HCA1500, HCA1200,HCA2200, HCA3500, or other bridged models should be excellent!
good luck

If you've got the opportunity to try before buying...
From one, whose experiment in bi-amping with different amps, failed.

foreverhifi: How do you feel about Parasound amps for bass? I wasn't sure, be clear now--and don't hold back:)

With regard to the question of monoblocks vs. bridged stereo amps.

Generally speaking stereo amps do not increase current output when they are bridged into mono. You may see an increased wattage spec but the current output is typically not much higher.

I say generally speaking because there are some amplifiers which, either because they are dual differential or truly balanced or whatnot, will be able to effectively double their current output when bridged into mono. You should research your particular amp and find out.

In most cases I am not a big fan of bridging amps into mono and prefer to bi-amp instead. I had a customer who was using two big 600 wpc. McIntosh amps bridged into mono and we unbridged them for him and set them up as vertically bi-amped stereo amps. He could play _much_ louder and the bass was much deeper. More current - that was the trick.
