New Leckerton UHA-6S MKII Portable Headphone Amplifier Announced (Update User Impressions Added... - Page 44

Good luck with it. Hope you enjoy it as much as I do :).
 

I have the same concerns with choosing op-amp too.

Seems like AD8610 is superior? I mainly listen to Japanese songs( pop and original sound track)

Will be using it with diymod iPod. Any suggestion?

There is no superior nor best opamp by default. It all depends on your overall setup (mainly your headphone but also others) as well as your sonic preference.

This is why Nick offers 3 different options for opamps and there are many other available out there.

 Almost all of my headphones are Audio Technica... but I don't really know what the exact kind of sound signature that I like. The UHA-6S MK2 has 4 option: AD8610 OPA209 AD797 OP627.

Hmm I am using ATH W3000ANV and ESW10 and both work very well with the OPA627, so much so that I didn't have any desire to want to try other opamps. Not sure which ATH are you using though.

Getting the UHA6SMKII fitted with OPA627 directly from Nick is very expensive. You may want to first order the UHA6SMKII with any of the other opamps. If you don't like them, you can fall back on the OPA627 later.

I got CK100PRO CKM1000 ES55 ESW9 A700, also a pair of Yuin Pk1. Thanks, I will try AD8610 first and then get OPA627 later :)   OPA627 usually is about 18-20 bucks I believe.

Generally speaking you want to find a good balance between your Amp and your headphones. While others may not agree with me I find Op-Amp 209 to be on the bright side. Treble sticks out that much more to my ears and it gets fatiguing. So I say stay clear of pairing sources or IEMs that are already bright with that Op-Amp. But then again there are others who will love that type of presentation. It comes down to your preferences. I say 8610 is the happy medium and 627 is more on the fun side. But I much prefer 8610 and 627 to 209.

If one generally prefer the warm sound then one may find the OPA209 to be 'bright', as of many who find a neutral sounding phone 'bright' due to the less accentuated lows and a more accurate representation of the highs without any roll-off.

I will use the OPA209 if I am doing audio mixing and the OPA627 for music listening.

Thing is UElover Op amp 8610s treble isn't rolled off and is quite neutral. So I think there's more to it than meets the eye in this case.

Well we all do hear things differently. Maybe I'm just getting fatigued mixed with bright but I associate the two in this case. At least from what I'm hearing that added clarity is making the treble that much more fleshed out and fatiguing for me, the digital artifacts in the recording could also be playing a roll in this as this OP amp really makes that apparent.. A nice benefit however is I tend to listen at even lower volumes due to this on this particular OP Amp but at the same time it also takes away some of the enjoyment factor. Feed a poorly mastered track to this Op Amp and it's heartlessly destroys it lol.

Pretty much with everything that I throw at it from the DX100 to the DACport LX. The fatigue is more so my problem with it than anything else. The presentation otherwise isn't that bad but still does sound a bit unnatural and artificial to my ears (kinda like watching blue ray movies, looks good but you know it's not real lol). Strangely enough my T1 amp seems to have more treble extension on it yet doesn't give me that fatigue like the UHA6 does with 209. So I'm puzzled why this is...
