could it be RR-12, Dafos?It's certainly true here.
I have a drum and bass track from the 90's with some deep bass, cut as a 45.
I can play it at 33 and my companion will near shit themselves in astonishment.
There's an intro, then as it builds out of nowhere comes a disembodied bass note that energises the whole room and makes your eyeballs shake. It causes you to question the laws of physics.
As the tune builds, that bass note becomes the bassline. But nothing beats the shock of that first hit. The depth, power and solidity are mind boggling.
Can you let us know how L10 compared against L1?I now have the CH L10 true dual mono preamp (4 box version) that has replaced my CH L1 true dual mono preamp (4 boxes) paired with my CH M1.1 mono block amps running in active biamplification mode powering my biamplified Rockport Arrakis speakers. Just a few comments on what I have read on this thread.
I do have the grounding switch on the L10's set to linked which ties signal ground and earth ground together (as I did on the L1's using the supplied jumper). I also use the L10 in no global feedback mode (local feedback only). I do prefer the no global feedback setting on the L10 as it provides a more involving and organic musical presentation (this is with the M1.1's set to zero global feedback as well). After about three weeks of break in on the L10's, my CH dealer visited me and we did some further listening evaluations. First we wanted to see the effect of adding some global feedback using the M1.1 feedback setting which allows adding global feedback in 10% increments. And since I run the M1.1 amps in active bi-amplification mode we only added the feedback to the bass drivers of the Arrakis speakers and left the global feedback at 0% for the tweeters, mid range and mid bass drivers. Over the course of three days, we compared 0%, 10% and 20% feedback on the bass drivers and each time we tried this, we both preferred the 10% global feedback setting on the M1.1 mono's for the bass drivers. Images were more right sized, bass was even more textured and the overall sound was just more natural to us. I look forward to hopefully hearing the M10 mono's later this year where the global feedback adjustment can be done in 1% increments.
As for grounding, one of the changes that CH has also made is adding a dedicated earth ground input (via banana connection) on the L10 power supply which did not exist on the X1 power supply used with the L1. I use a CAD Ground Control Reference (GCR) grounding box for my front end components and with the L1's, I connected the signal grounds of the 2 L1 boxes to the CAD GCR. I also started this way with the 2 L10's. With my dealer here, we compared grounding with the signal grounds of the L10's to the earth ground of the L10 power supply. We both felt that using the earth grounds of the 2 L10 power supplies was even more effective than using the signal grounds of the L10's. It improved the sound in similiar ways, just more so.
"MADFLOYD: It definitely has changed with break in. The bass was HUGE when I first put it in my system (when it already had 40 hours on it or so) and it was a bit on the dark side. Well it has totally opened up and while there isn't as much bass anymore, there is still more than with the L1.
Two other design differences between the L10 and L1 that I forgot to mention above. First, the chassis of the L10 and its power supply, while they look almost identical and are the same physical dimensions as the L1 and X1 are quite a bit stiffer and denser than the L1/X1 chassis. A lot less vibration when you rap your hands on the case itself - a significantly stiffer case. And second, with the L1 and its optional X1 power supply you had to use 2 power cords - one for the L1 itself and one for the X1. With the L10 (using the 2 supplied umbilical cords from the power supply to the L10 head unit) only one power cord is required in total and that is for the L10 power supply.Can you let us know how L10 compared against L1?
Thanks so much LLoyd.Fantastic, Arnie. You've continued to explore the outer frontier of high end audio...and sent a signal back thru deep space!
Code Of Practice - Can We Change The Future Remixescould it be RR-12, Dafos?
it's from 1983.
I would love to hear the answer to this question, too. My M10s are inbound. I'm also eager to know about the Interconnects and Cables that you've most enjoyed with your L10/M10 combo if you're open to sharing. thank you in advance. SGFor those lucky audiophiles who own CH M10 amps, which amp stands are you using with the M10? Why?

What is your opinion on Vortex footers versus Nimbus footers?I don't own M10s but do own M1.1s and I have dipped my toe into the HRS waters.
I started with HRS M3X2 platforms under each amp. Compared with my previous amp stand (which was nothing special) the difference was staggering in just how musical it became. The sound cleaned up and beauty just poured through.
I've since augmented this with HRS Nimbus footers (1.5" x 4) between the amps and the HRS platforms and the difference is not subtle. I'm now experimenting with HRS Vortex footers (in place of the Nimbus).
I am an instant fan of HRS. And of course I believe CH electronics are superb works of art. A great combination imo.
It might be system dependent but for me while the Vortex 'calm down' the mids & highs and increase deep bass, they reduce the amount of midbass which results in too much of an anemic tonal balance.It feels like the answer about the L10/M10 would be really interesting.
