Thanks John. I've been advised the Yggy sounds better after it's been on 24/7 for two weeks, this advice was given by a head-case user [ I won't mention his name for assuming he wouldn't want me to ] and the gentleman I ordered the Yggy from. What I'll probably do though is leave it on all the time, which I was told would be safe to do, another thing I like about this order, is the Yggy is under guarantee for five years. About the K-01, when I got it in 2011 it cost £15,000, but I'll be lucky if I get a third of that amount, same with the 009's if I were to sell those Earspeakers, however I'd be confident in getting what I paid for the BHSE assuming I were to sell that stats amp, that won't be happening though unless I end up in deep shit and need money desperately, at the moment I've no worries about that. Regarding the Orpheus 2, even if I were wealthy [ which I'm not ] I still wouldn't get one, simply because it seems the HE-1060 can't be used with anything other than the HEV-1060, therefore if/when anything happened to that AMP/DAC, and it had to be sent off for repairs, then those headphones can't be used. This is why it's hopes Sennheiser come out with another new stats headphone that can be used with any stats amp.
