It appears to be neither a conventional port or a transmission line. If it were a transmission line, back of the napkin calculation says it it tuned to approx 200 Hz. If I were going to stuff the port I would probably cut a piece of foam and maybe try a couple different densities. Also, the...
I also am still using SB Touch as my primary streamer. I don't think I have updated any software in the last few years. I don't seem to be having any issues, but what do I know? Can you point me to a link that explains it in detail? I probably have multiple LMS installed, but I think I only...
One thing I would be concerned about: The Ethos uses DSP in its internal crossover. My opinion is that the DSP is what allows the phase response for the woofer and panel to be close to the same at crossover. This is what makes the woofer and panel integration work better than on older models...
For what its worth, I have my Montis placed with the panels 3 ft from the front wall. I have plenty of room to move them out farther, but I like them there. My room is totally different from yours though...
A while back I down sized as well from pre and mono blocks to an integrated (Pass INT-150). I think the Pass may sound marginally better. In your case, the the BHK gear has tubes in the input sections of both pre and power amps. The Gryphon is all SS, so expect there may possibly be some...
You will need to remove the back panel. There is a thread here that describes it:
Replacing the amplifier module in a Summit
Looks like the binding posts are held on to the amplifier board by 1/2" hex nuts. There may be additional hardware under the PCB. The thread linked ahs lots of...
I hate to complicate matters, but when I was shopping, I found a large performance jump going from Theos to Ethos. The Theos just didn't do it for me. Bought the Ethos then upgraded fairly soon to Montis.
I'm sure it would be a challenge but apparently ML managed it with the CLS series. In any case I am perfectly happy with the bass integration of my Montis.
