Have:
Electrostatic:
Stax SR-Sigma - came in today, looking forward to auditioning them
Stax SR-Lambda - Wonderful headphones, they do very little wrong and ton of things very very right
Stax SR-Gamma - very good headphones, but a level below Lambdas
Stax SR-303 - Wonderful headphones, compete with SR-Lambdas head to head. Dynamics on these are the best of all of my headphones, simply explosive
Stax SR-001MK2 - excellent headphones, great tonal balance and warm midrange
Orthodynamic:
Yamaha YH-1 - good cans but cannot match modded YH-1
Yamaha YH-1 (ericj modded) - compete with Stax since they are almost as fast, they got Gamma beat in some respects. The only had thing it the soundstage
Fostex T20 v2 - I modded these and they are just as good as YH-1 and have excellent bass and mids together with superb transient response
Dynamic:
Jecklin Float 2 - huge soundstage a bit to warm sounding and unfocused
MB Quart Phone 85 - Love these, huge soundstage. Great analytical sounding cans. Don't have deep bass and it's a shame
MB Quart Phone 70 - good closed dynamic headphones
Audio-Technica ATH-A900 - very versatile, sound good unamped
Audio-Technica ATH-SJ5 - nice portable headphones, a bit colored
Armature:
Etymotic ER-4P & P-to-S cable - very balanced and flat sounding, great for commute, tiny
Had:
K340 - I
loved some things about them, but they have a lot of issues. The tubby reverberation killed them for me, they just had to go
AKG K280 - nice headphones but a bit too dark and muddy for my taste
HD600 - I used to like them, not that I have Stax not so much
HD500 - very muddy
HD433 - cheap and not that bad for the price
Magnavox 1A9217 - good entry level stats, a bit unfocused
Audio-Technica ATH-EM7GM - not bad at all, but the fit killed it for me
MB Quart Phone 15 - OK, but nothing special, typical MB Quart sound
Stax SRD-4 & SR-40 - good entry level Stax, but other Stax do everything better
Lots of other cheap headphones and buds.......
Tried:
SR60 - don't like
SR80- don't like
Stax SR-X - I cannot makeup my mind about these, need more time with them
Stax SR-404 - sounded almost exactly like SR-303 to me
Yamaha YH-100 - great headphones that improve a bit on YH-1
Realistic Pro 30 - good ortho phones that have potential
Koss A250 - very fast and acurate, but a bit bright for me
Koss ESP6 - did not like these at all
Koss KSC-75 - nothing special IMHO
HD650 - see HD600
AKG-K1000 - did not like the un-headphone like nature of these, I rather listen to my speakers to get this kind of presentation
