Eventually I hope to do an NFB-16 vs. O2 vs. Dragonfly vs. HP-P1 vs. DX-100 vs. balanced amps comparo as I'm being lent both an RSA and ALO. I don't have custom IEMs however.

I have quite a few portable amps and a few USB DACs (HRT MSPro, Audinst HUD-MX1, Audio-gd NFB-16 and will have the Leckerton UHA-6s2), but I definitely don't have the expertise to do any measurements etc...

Unless someone in Brisbane can do that stuff, seeing someone is organising a meet in Brisbane in November but then I'll be in Hong Kong (maybe Japan too) in those days, so I will probably meet up with googlei or whatever his name is. :P hahaha

I read about the new Leckerton, isn't 18dB extra gain overkill for portable use?

I mean I switched from my Clip + to a iRiver H10 (Rockboxed!) because the iRiver sounded more pleasant and a more powerful headphone out was needed. 10dB is more than enough in most situation or am I missing something?

Uh no....


Ask Marv if you don't believe me.  He heard both when I had both though it was the Stepdance one, not 2.  I know they use the same opamps now but there's more too it I'm sure.  I started raving about the opa209 in the UHA6 mk1 then Jan switched to it in the new Stepdance and Nick makes it the default opamp.  All coincidence.   :)p17

Anax -- do you recommend going with the standard OPA209 over the OPA627 on the 6S.MKII as well?

Yeah, I don't have the 2stepdance which has got the op amp you mentioned and I have read the leckerton thread which you say the 627 for more 'tubey' sound too.

I didn't know why I had that feeling that they sound similar. :P  So the leckerton is better than the stepdance?

In general terms yes if getting the most information from your tracks is what you want for your amp.  The 8610 is more fun 'V' sounding but measures flat and has less separation and micro detail.  The 627 would be best for brighter phones looking for more body and organic sound.

I can't say due to people's varying preferences and gear.  For my tastes I hear more information and get less fatigue from the Leckerton w/ a 209 than the Stepdance or O2.  All I can say w/o pointing to measures which the O2 should win on but doesn't based on listening for me.  Can't find much data on Jan's stuff though I'd be more inclined to support his work than RS based on listening.  The RX3/L3 are beasts on another level w/ different hits and misses.
