I have the 2.0. I was told that 2.1 has better bass extension and dynamics, but the $15,000 upgrade is outrageous. I can get an excellent pair of speakers for that sum. I've been a loyal customer having owned the C1.1, D1, and presently D2, but there upgrade pricing is leaving me with a really distaste for this company. I'm thinking of abandoning Raidho altogether.

Same thing happened to me with my C3 speakers..I wont buy Raidho again,they change their lines way too often,bad money spent IMO
