Here are a few updates:
1st, the new Blox, which was known as BX3 during the prototype stage, will be officially named TM7.
2nd, price will be announced at the end of the month when it is officially released, so check out Blox's website regularly. I can't tell you much as they didn't tell me either.
3th, they still haven't decided whether to continue the production of M2c or not.
4th, TM7 sounds AWESOME right out of the box, but I was told it still needs 80hrs of burn-in to settle down.
5th, did I say it sounds AWESOME?
6th, yep, A.W.E.S.O.M.E.
Oh, last but not least - the sound impression: It still has the M2c sound, lush and warm, but more reference and less fun. In a way, I'll say it is the perfected M2c, so to speak.
