System needs more watts??

Can BAT75SE be monoblocked? you might ask...if so, try monoblocking them. depending on how the BATs respond to impedance, you could end up with 150-300 watts of power into your speakers. Some amps are designed for his, or are easily switched by a good audio tech...something to consider.

Hi, yes the 75SE can be monoblocked to 150SE's. It's pretty easy, you can buy an internal kits (requires just a little basic soldering or external jumpers from BAT.

I did this a few years ago (I did post if you maybe search...sorry I don't have the links handy). I was feeling like my BAT 75SE was running out of gas with my Wilson Watt Puppy 6 and 8's at the time. It was distorting...more the soundstage collapsed some and dynamics (exactly what you're saying)

The second one is a big deal...it's not just more power, but it's better power..these amps now running each side of the amp in a balanced mode, lowering the noise floor, increasing the dynamics...it's just better + a lot more power and current.

If you love your amps, this is a good route to go...My issue was I live in Tx and my room upstairs couldn't handle the heat output....so I moved to Ayre MXR's. (another possible idea)

Hope this helps, good luck, you have a great system !

Broken,

Jfrech is one experienced guy, and sounds like he has actually done what i was suggesting with your amps. FWIW, i also have spoken to a former BBC engineer about my old CJ MV60s (55 watts/channel) when i was thinking of how to get more juice, and his description of what would happen exactly matches what Jfrech just described above...way, way better in all ways...more power, more control, superbly better bass damping, fuller soundstage, better macro and micro dynamics...

one to consider given that it sounds reasonably straight forward to do.

Sounds like a second 75SE is definitely worth considering. But, before
monoblocking them, why not try vertical biamping with two 75SE's; one
channel for the mid/low and the other for the tweet. Can't speak re these
amps specifically, and it sounds like Jfrech got excellent results, but it is
well documented than there are many examples of amps that when mono
blocked yield the benefits of the additional power, but also lose finesse
and purity. It may not be the case with these, but costs nothing to try first,
and is a simpler possible solution. And if you already like the sound of the
amps it can only be a step up; no risk of any losses.

Agree with Frogman...certainly worth a try first. some amps dont mono well...but most often those are the ones that are not designed to be used as such. sounds like the BATs might be designed for this, given that supposedly it is an quick internal switch/setup.

in any event, you should get some benefit from Frogman's approach...though if the BATs are designed for true mono...you should find that is even a step up (i am told...not actually compared myself on BAT).
