100+ Head-Fier
Despite several days of looking for similar testing Mitcham ECC82 singles, I went ahead and bought this set. A bit pricey but not terribly expensive.

Done buying for now.
Interesting @TK16 - he had a pair earlier, pretty much the same, but Blackburn & same price - I bought em but was too embarrassed to admit I paid that much, so now the cat's outta the bag. I'm done buying also (but I've said that before)
