Slowhand- Sounds like an expensive "upgrade". Have you thought about selling your unit and then buying the new version instead? The cost difference can't be that much and it might have a higher resale value as a "new model", not an upgrade. Just a thought. As a side point, many years ago I sent my modulus in for an upgrade (2B to 2C) and was extremely unhappy with the three month wait and constant excuses when I was told to expect a three week turn around. If you do decide on the upgrade path, try to get every assurance before you send it in that it will be completed and returned by an acceptable date. I hope that they have improved their response time. (I was so displeased, I sold the unit as soon as it got back without even taking it out of the box and have not owned another piece of AI gear since then). Goodluck with your pre-amp endeavors.
Audible Illusions M3A update
I am considering sending my M3A back to Audible Illusions for the newest version. The cost is $1250. My question is this. Has anyone out there had the opportunity to compare the sound of an older version of the M3A with the newest version? I am told that many improvements have been made, such as bigger power supply (which in now better shielded). New volume pots, improved line stage, etc. Can anyone please give me an idea as to wheather the improvement in sound is worth investing in the newest version of this preamp.
