Speaker cables are Analysis Plus, with a double run for internal biwiring; there are also the connections to the REL Strata III subwoofer on the speaker terminals. From the CD players, I'm running Tara Labs interconnects.
I'm using AP oval 8s and solo crystal cables with my INT-60.
Seems to be a good combination.
I have no complaints about the Analysis Plus cables--I'm not convinced my ears are good enough to be able to compare cables and interconnects, nor am I rich enough to experiment with various brands (some of which, as everyone knows, can get quite expensive).
I've had these for well over 10 years now. I do hear a difference, but I've been happy enough with these that I don't want to buy anything else, though I have tried a few in the past. Don't want to spend the money either.
They have worked well with almost everything I've hooked them to.
I see that you are using a Marantz cd player w/ your Pass Labs amp.
yes, the SA-11S3 SACD player. It works well with the Pass amp. It one of the few of their SACD players with balanced out.
Very good combo.
Wow, parallel worlds: pass labs, analysis plus, and marantz!
I've got ML, you have Maggies.
LOL...we're like related or something!
But, Pass Labs, Magenpan, Analysis Plus, Marantz...all very solid companies, I think, and this is important to me when it comes to audio gear.
Interesting mix of cabling- slapshot.
Note, I've taken the REL Strata III out of the system as it cannot run with this amp using the Neutrik connection. So, more downsizing as I'll be selling the sub as well; I don't think it really adds that much to the 3.6s, actually.
Curious about your REL comment. I currently have the INT 60 in for review and I use my REL Strata III on the high level input without issue. You do have to connect the ground to the white grounding post or it won't work.
For me, the white grounding post does not get rid of the hum. If I connect the black Neutrik wire from the sub to the black binding post of the speaker, the sub does not hum. However, I've been informed that this connection is problematic with a balanced amp such as mine because the black speaker terminal is driven to negative voltage and is not ground. Apparently, at issue is that REL typically connects their ground to the third pin of the AC mains power cord. In that case the negative DC rail of the INT-250 is driving straight to earth ground.... not good practice. If you have two subs, no problem.
I wasn't convinced the sub was really necessary with the 3.6s, so rather than risk damaging either the amp or the sub, and rather than try to connect rca connections, I decided just to remove the sub.
Certainly you don't want to risk damaging your beautiful equipment. And as you said, no, don't plug it into the neg speaker post.
I have had similar issues with balanced gear, like the Benchmark AHB2. I don't know why I am not having any problems with the INT 60 (or my XA30.8 for that matter), and you are, but it's not the first time I've heard of this with other gear, just not Pass Labs.
Maybe I need your other Strata III! :))
Enjoy the amp. I'll bet it sounds great on those Maggies!
