Experience going from Morrow MA-1 to MA-3?

Interested in hearing from anyone with recent experience going from Morrow Audio's MA-1 to MA-3 interconnect. Have MA-1s now. Curious what benefits you heard. Have searched here and read "you get more" as you move up in the line. Is MA-2 or MA-3 the better option? Looking at their trade up program. It's definitely affordable.
Hey Runnin - Thanks for the reply. That's nice to hear about the MA-3 stage depth. I tend to agree with you and believe increased resolution carries spatial cues that contribute to soundstage perception. I'm a little concerned however that increased resolution might come across as hot and harsh. Any comments about tonal balance of the MA-3 vs MA-1? Thanks again.
Harshness has been a pet peeve of mine as when I first got my current speakers I didn't realize they could be forward and bright sounding with the wrong electronics/cabling. I should say currently I have Paradigm Sig 6 version 2 speakers and Parasound (A21, P7) electronics with an Oppo 95 player.

I have pushed my system pretty loud with different tracks, and am quite happy with the sound, not hot sounding compared to the MA-1 at all. I'd say that the improvement over the MA-1 might be a touch warmer even. I talked to Mike Morrow personally(A very approachable guy who is willing to take the time for his customers) and asked him about brightness with the Eichmann silver RCA connectors. He said they wouldn't add any brightness over their regular connectors and he was right. That being said, if silver based connectors don't add any brightness, then the MA-3 with regular connectors wouldn't be an issue either.

No affiliation, but I respect a guy like that enough to mention it.
OK. Thanks once again, Runnin. My system is posted. Silver per se hasn't been a problem. I'm using Clear Day speaker cables; in fact the Clear Days brought a huge improvement - as much as a major component upgrade, to my ears. BUT the Totems use a metal dome tweeter and don't cut bad digital recordings ANY slack (e.g., Hendrix - Bold as Love: Todd Rundgren - A Wizard a True Star being standout hard-to-listen-to examples from my CD collection). Component matching - cables being a component - is definitely something to pay attention to. Great feedback from you on the MA-3s. The current trade up program at Morrow is hard to pass up right now.
Hmm, I've heard good things about Clear Day cables, thanks for the tip. I know what you mean about metal domes!
You get a hankering' to just try something different, Runnin, give Paul Laudati at Clear Day a call. He has a 30 day money back policy. Good guy to work with.
