morrow audio

Ok, here's the story. I bought a 2 meter phone cable from Morrow Audiu, hooked it up, played an LP and it was HORRIBLE. Muffled, muted, sounded like crap. Contacted Morrow to return it, he suggested I "burn it in" using a CD player, I reluctantly did this. 50 hours of this treatment later the cable is beautiful! You just read a post from a convert.

Bryon, I disconnected the phono cables then repeated the burn-in for an additional three days using the XLO burin-in CD track, and they sound nice once again. Any thoughts or ideas you have are welcomed. I had not used the TT for more than a month, possibly a bit longer.

A short follow-up; the issue SEEMS to be that with lack of use for some time there is a regression of the "burn-in". I play music every day, so if I had interconnects and speaker cables this would not have occurred. Its the phono cables that got very little use that allowed this effect to surface. Maybe its not a surprise to those in the know about these cables but it is to me.

I find it to be surprising also, because I'm not sure how the miniscule amounts of current that flow through a phono cable could result in a difference between when the cable is used frequently and when it is not used for some length of time.

If you are using a low output moving coil cartridge, depending on loading the amount of current would be no more than a few millionths of an ampere with most recordings. If you are using a moving magnet cartridge, it would be far less than that.

Al, Using a Grado Sonata. A mystery, but a true fact none the less.

Hi Repluso

I don't know if you saw this but Morrow details the break-in process here as well their findings through the various parts in the whole period.

They included a printout of this when they send you your cables. Was it not included with your phono cables?

Morrow is pretty up front with what you will be in for with them. If you are having a problem with them why not contact them directly? They all seem like reasonable people who will work with you. Maybe they can break-in the phono cables for you. They did that with some speaker cables I bought from them. I told them I was reluctant to buy higher level cables from them again because of the extensive break-in required. I just didn't want to go through all that again. They offered to break-in the speaker cables I wanted before they would ship out to me.
