Morrow uses UTP (unshielded twisted pair). From an EMC and grounding perspective (you know the boring stuff you can measure) that is actually the worst way to do an unbalanced interconnect. It's very possible what you like about them is the added sparkle all the grunge they pick up add to your music. The basic cables are $55 so they are not ripping you off, even if their 'technology' is pure woo.
If you are happy with them, that is good, but they are not a good choice for accuracy or signal integrity. Plain old belden coax is way better, but without the great story!
I have the MA3's, I felt comfortable trying them out for $140. And its pretty common to hear how the dielectric interferes with audio.
I do hear a little grain compared to the BJ's but they more than make up for it in timing.
Its not the added interference that gives them the attributes I like, I can guarantee you that.
I dont have a bad enough problem with interference for it to be an issue.
I think the BJ's sound good but their ability to get the sound location ques are no where near the Morrows.
And I do believe that ones particular system, might need something completely different.
I was discussing Morrows on another forum and a member just got some used MA1's for his cd player. All he said was that he had a tear roll from his eye, listening to one of his favorite albums and that he wasnt going to get rid of them.
I care less about the plain old signal integrity, what about the correct phase reaching your amplification electronics. Thats when you really connect with the music.
With how many seem to have great experiences with Morrows, and lots of them are return customers upgrading. Their must be something to his design philosophy.
Guys who have extreme RFI issues, like with the Mani. They probably should go a different route. Couldnt hurt to try them out for 30 days and if they did hear excessive emi/rfi, just send them back for refund.
And I will say that a little of the interference could be adding some sparkle and tone. But its the location and movement of sound, that was the biggest difference compared to BJ's.
Makes me want to try a DAC known to have great phase/timing with them.
Glad the OP enjoys his IC's.
