Has anyone else done the upgrade from 3.0 to 3.1 - I have M60s of very recent vintage with power and vcap upgrades. It does not seem expensive. I do wonder what the changes are internally and how the perfomance changes, improves? with the upgrade.
Yup! MA-1's though. Much lower noise floor, now they are essentially dead quiet with no preamp signal. Slightly better imaging and detail. It is, IMO, a worthwhile upgrade if you can do without them for a couple of weeks. Mike
