Morrow Audio MA1 ICs

Have any of you guys here ever heard about the break in trick of applying a 9v transistor radio type battery to ICs. The fellow who told me about at a fest a few years back said that you want the negative terminal on the end that will plug into the amp, and the positive on the end that will plug into the device (CDP or whatever). Current flows from negative to positive, so this will break them in directionally as well, even though we are dealing with AC voltage. He also said it takes just a second, no matter what the manufacturer recomends. I never tried it, as I use a Cardis sweep LP for most burn in jobs. It just came to mind when I read the 400 hour deal. I wonder what is actually happening to the wire that takes so long, do they say? I think if I were to try the above mentioned "trick" I'd first try it on some cheap cables and use a 1.5 volt battery, or even a variac set for 1 or 2 volts to get AC.:scratch2: I think I might design a cable burner inner. I used to have a lot of trouble with belts stretching when I did residential AC and heating. I'd put on a new belt, and in 30 days it would be too loose. I made myself a belt stretcher with a motor, a couple pulleys, and a fairly heavy spring. The problem was eliminated, as were the call backs.:thmbsp:

Now that's a cool trick. I'll have to remember that one.

I just bought a pair of SP3 speaker cables, MA3 interconnect and PH3 phono cables. They should be shipping soon. I'm pretty excited as these are my first upper level cables.

If I recall, the MA-3's are the sweet spot in the IC lineup. Let us know how they sound.

*EDIT* Almost immediately after I wrote this post i ordered two pair of Morrow Audio MA-3 IC's. Also Jay, I asked about the 1.5v battery trick and he discounted the idea by claiming that the cables needed sine waves to properly break in. He gave me a bunch of reasons so I hope I got that correct.

I just received two pairs of MA-1s in the mail. I put one pair between the CD player and the pre-amp replacing some $25 cables from Parts Express. I really did not expect much because I heard no difference when I upgraded from cheap RCAs to the PE stuff. I knew that I could return them if they were not an upgrade so I had nothing to lose.

I've been listening to the new Jack White solo disc a lot lately so it was a natural choice to use for a little test. The immediate results were very surprisingly obvious: louder, clearer, bass and treble and a better stereo image. I have spent hours on speaker placement and room treatments chasing that coherent stereo image.

This is a worthy upgrade that I would recommend to anyone still using cheap interconnects. I wonder how they will sound after the breakin period!
 
Part of my surprise was due to the fact they seem to have the exact same plugs as the PE cables they replaced! So it's all in the wire?
 
After reading about Morrow cables here and on Audiogon, I tried a pair as well...and then slowly went about putting them in my entire main system.

PH1 between VPI Classic and PS Audio GCPH, MA 2 to the Yamaha MX-830 amp, then a run of SP1 to my speakers. I also used some MA 1.1s between a Peachtree dac/pre.

Like you all said, it really opens up the sound...if it didn't, I would have returned them and got my money back (Mike Morrow will take them back up to 60 days from purchase). It's easier on the wallet to believe that cables don't matter, but in my room, with this equipment, that's just not been the case.

I also upgraded from Blue Jeans -- which are also excellent cables.

I'm thinking about getting the PH1. Can you tell me what you replaced and what your opinions are on the PH1.

Thanks!
 
I ordered a set pf PH3 and they just shipped, so I should have them Sat or Monday. But no breakin, I prefer to let my system do the breakin.
Remember with the PH model the number represtents the number of runs of shielded cable within the whole cable....The higher the number the more detail that is suppose to come thru. So PH6 would have 6 runs of versus PH1 has 1 run.......

I am very happy with my MA1.1.......After this PH3 purchase I have a couple more I/C and I am done.
My speaker cable, for now I am very pleased with the Belden 10AWG 5000.

will be interested to hear your thoughts on the PH3.

I'm awaiting arrival of my order...can't wait!
 
I did not experience any real changes during the so-called break-in period. However I did leave the CD player on repeat while I was not listening. So I heard the cables with no hours, then 20 hours, then 40, 60, 80 and so on. I did not notice any changes. They sound very good.
 
I picked up a set of PH3s for connecting my Thorens w/ cardas rewired SME 3009 to my preamp. Before I was using a set of Mogamis which weren't bad. But the PH3s definitely made an improvement. Overall solid improvement all round but most noticeably more open, clean, and nicer top end. Got them on sale w/ easy pay, ended up being round $40 bucks a month for 3 months.
 
I'm actually surprised by the degree of SQ improvement brought by the MA1.
The MA1 is between my SACDP and amp and I feel as if I'm rediscovering the SQ of my digital discs.

For the money you spend on it I think all non-believers should give it a go.
 
If anyone's interested, the MA1 IC is back on sale for 29.99 at Morrow Audio. I ordered a pair, just couldn't resist!
 
I ordered some too

I just ordered 3 sets of the MA1's. I installed these on my dad's stereo set up and it sounds very nice. :yes:

I will have to try these against my Audioquest cables to see which sounds better.:scratch2:
 
It's funny, I have a pair of the MA3's, but heard such good things about the MA1's I thought I'd give them a try at half off.
 
Big fan of the MA1's here. I got one pair a year or so ago, and have slowly added a pair at a time till that's all I'm using. To be fair, I've never tried anything more expensive. But for what I consider to be entry-level nice cables, they really add lots of depth, dimension and detail.
 
Writing in support of the generally positive feedback on the Morrow cables. I have a full set: power, speaker and interconnect. I really like them - haven't felt the need to change them out in over a year (and for me that's darn good). I really haven't noticed much in terms of break-in changes as other parts of my system change frequently. All I know is they sure sound nice to me.
 
But I was surprised to read the break-in guidelines and learn that 400 to 500 hrs is recommended..

I'm guessing that 400-500 hours is either so you keep them until it's too late to send them back, hoping that they will suddenly change or so that you will have completely forgotten if there was a difference in sound with the previous cables or not.

I'm somewhat tempted to try his stuff though.. either that or Anticables. I use Bluejeans IC's and speaker cables currently. Haven't bought fancy IC's or speaker cables in many years. Last ones I had were Tara Labs RSC Prime and MIT Terminators. Still have some MIT IC's.

It's true that the gradual break in time could be a gimmick of some sort, when I broke in my MA3's, for much of the time I couldn't hear any dramatic changes, but at the time I had some other cable in the signal chain so it was somewhat hard to know what was going on.

After I broke them in, a few times I switched things up with other gear, and noticed some harsh sounding effects for a little while, then things settled down. I blamed the other gear at the time, then after remembered that Morrow recommends not disconnect/reconnecting the Morrow cables or moving them around a lot as they will have to settle in again.

Again, hard to know exactly what went on, but they do seem to have a good reputation. You don't hear stories of guys feeling like they got ripped off or anything.
 
I ordered 2 pair of mr1 for my cdp and mr2 between amp and pre, about 10 days out. They are also including some break in time for me. They are having a used cable sale now with 30 0/0 and another 20 0/0. Seems like the best deal since they have break in time already
