The 6900s are very expensive. I see 4 on EBay with the bid starting at $1K!

So no less than $500 a pair! Glory could be right about price to performance ratio.
There is ONE good roll for the ECC40 and its the Tungsram brand! Its shorter, more robust and allegedly has an even clearer midrange! All the other brands of Ecc40s are identical and made by Phillips despite the branding. A Spanish guy has a pair on ebay for about $25 a pair plus shipping. I scooped up the Eastern European ones a day or 2 ago, so be on the llokout for them.
Unlike what Glory says, i think the ECC40s are GREAT sounding, but the Phillips ones are not so robust as they are hit and miss with durability! For the money, they have the best performance and the Tungsram version is the way to go, apparently.
Glory, link me up by email for some scoop!
