Now this is a drivers that I'm very interested in. Built in BSC, high sensitivity, great power handling, and very valve-friendly impedance.

I probably won't be able to afford it.

no no no no Mark, we are missing the whole thing here...

what i need is a field coil 100db sensitivity driver! what should i do with this one?

i'm so a newbie i feel like a i can pretend things like kids... btw i'm waiting for the chr-70 and the alpairs 10 to be delivered.... and also for those plans by Scottmoose to be revealed

here in italy your official reseller is selling the chr-70 at an unreasonable price, now in temporary reabate but also unreasonable. i think you should take some kind of policy about this things. by the way i ordered abroad.

Hi there,

I'm completely agree... Another example is relative to the binding posts. The price from Mark Audio site is 19 USD (at today about 13,70 Euro) for 4 pieces (with 2 connecting plates for bi-wiring), the price from the italian reseller is 8 Euro for 1 piece, so for 4 pieces the total amount is 32 Euro! And, I think, without the 2 connecting plates...
Really sorry for the OT, excuse me...
Bye,
Christian
