b&k st 1400 or b&k st 125.2


Or neither? Asking prices are: st 1400 ($240) used, st 125.2 ($300) new demo from a dealer. Main use will be center channel, or possibly front right and left for movie playback and I'll bridge my classe ca-150 and power the center with that. What do you guys think? I'm open to suggestions on another budget ($300 or less) amp also. Thanks in advance!!

I did try it. I could only listen to one channel as I only have one amp but it sounded way better bridged. So much so that I want another ca-150 to run my center channel during movies and then in bridged mode for two channel listening. I was just curious if you were thinking that bridging an amp was bad for it because of impedence and heating issues etc. What's your take? Thanks by the way!
if you already have the amp, you can just try it too. I have and found in all cases I preferred "single stereo" (even though I always have this nagging thought that I have a channel going to waste!)
the reason not to bridge is sonics. I don't understand the technical issues, but was told by 2 manufactures that amps designed for 2 channels are optimized for 2. When you bridge them they won't sound as good. So unless you need the power and you're not concerned about sound (eg - driving a subwoofer), run it as a single channel. For many designs, a 2 channel amp running only 1 channel will produce more power than rated due to the fact that the idled channel is not placing demand on the power supply.
Bdgregory, thanks for the helpful input! I never even thought about how the b&k was going to match up with the classe even though that should have been something to think about. I'm thinking that the b&k might be a warmer, sweeter sound which I was actually excited about so I could compare a different amp in my system and see if I liked it better than the classe. Hmm, now you've got me thinking though.

Another question for you is why would you recommend that I don't bridge the classe?

Anyways, thanks again for the help! I appreciate it!
I have the 125.2, and have had the st1400, and st1400ii. The 125.2 is excellent for that money, and the st1400ii is essentially the same amp - both are great for HT. I wouldn't go $240 for the older ST1400 amps. the B&K amps can't be bridged, so you'll just let one channel idle if used for center. I wold also do this with the Classe though rather than bridge it.

The only ? is how they will go with your Classe. I'm not familiar with that amp, but this is the question you need to answer if you're using both for the front.
