More accurate impression will be out once I have chance to volume match everything. By then, I'll probably be writing them for my sub-$200 portable amp shootout. For now, I'll just kick back and enjoy

Looking forward to your final thoughts. After buying the UHA-4 I'm wondering where to go from here and I'm not really interested in any side grades.

That's interesting.  Any more impressions would be good if you'd like to compare to the UHA4.  I think you have the 209s as well?

Not much to say, really, and, frankly, I don't have much experience reviewing gear, so while my ears are very, very good at telling me what I'm hearing, translating that into English is...spotty at best.

The C421-8620 sounded v-shaped, with a flat, congested soundstage, and mediocre instrument separation. It was...sort of an upgrade from a Caffeine Pro (in technical ways, and step back in musicality, whatever the hell that really means), but I wasn't sad to see it go. I was really after something neutral(ish), with good detail and soundstaging. I'd come into this hobby assuming I was a basshead, but it turned out (not surprisingly, the more I think about it) that I was a total detail freak (at least within my price range).

The UHA-4-209 has been great so far. It's got a little punch, as ClieOS said, and really seems to open everything up (detail, soundstage, etc.).

...the UHA-6S II?

Great minds think alike

I'm pretty happy with my new Freakster Mobile Rig thus far

Thank you. I wanted to get the C421 but now I know what configuration I should go with.

UHA4 is quite nice turok. I love it with the Stock OP Amp. Very musical and the mid range is lively. I really want a UHA6MKII

Why the UHA6MKII.............................anything special about its SQ vs the O2?
Now you got me lost again! are you happy! UHA4 or C421?.......

I don't have the C421. I have the UHA4. I want the UHA6MKII because it would be an improvement IMO to the UHA4. That is if the volume pot is like that of the UHA4, you'll have more power and better dynamics overall.
 
Now going from Anaxilus' comments, he found the UHA6 to be even more transparent than the O2 amp. Not saying this is fact but a rather interesting point. Then again he isn't using the Stock OP amp. I am very happy with the stock OP amp in the UHA4 however (I don't like too much transparency as it would offset the balance with my rig).
 
Honestly I don't think you would be upset with either the 4 or 6. But maybe you should contact Leckerton and find out if the new model will have a digital pot like the UHA4. Also find out if it has cross-feed. If not then it may be better to get the 4 based on using IEMs. The 6 would be better suited for full size cans otherwise.

Geez,
 
I'm trying to make that decision too.
 
UHA--4 vs C421
 
really can't decide...

After a few days of listenning to my UHA4 with Aud 5x, I found the sound to be projected a little further in front of me instead of a very in the face sound, the sound is "tamed" for the lack of a better word. Bass also seems to do a little better now. Portable amps are still very limited in what they can do in my noob opinion.

It may be your noob opinion, but I find it more or less objectively true, IMO.

Nice to know that I am not the only one out there that feels this way. Well.....since I bought it, I'll still be using it, but lesson learned

 

[radiohlite]

i was pretty unimpressed with this amp since i got it basically to make my audiophile orchestral albums sound as vast and dynamic as i know they can [on ER4s], but didnt really hear much of a difference between the Leckerton and my rockboxed ipod hp out except maybe more treble and clean gain
 
...well, i just started listening to my old thrash metal collection which has been sadly neglected in my search for other musics....and i'm astounded at the purity and speed im hearing!! 

 holy cow. metal nirvana
 
guess i need something fruitier for classical tho

For Classical and ER4S, I think you should take a look at JDS's C421 with the AD8620. While UHA-4 does sound really good with IEM in general, C421 with ER4S are just match made in heaven.
