New Leckerton UHA-6S MKII Portable Headphone Amplifier Announced (Update User Impressions Added... - Page 100

Thanks:) that looks good!
post #1487 of 2097

I almost sold my UHA-6S Mk.II! (shame on me, I know)

Because I thought I might want to try a different amp (Glacier) and see how much better it can get.

 

But now I don't think I'll ever part with the UHA-6S Mk.II.

 

I swapped the OPA209 again for the OPA627 today out of curiosity, since I have noticed recently that the OPA209 was becoming more and more strident and harsh. And to my surprise, the OPA627 today no longer sounds dark, muddy or cloudy. It's very smooth, resolving, and it pulls details out just as well as the OPA209 does to my ears, but that strident and harsh feeling of the OPA209 completely goes away! Soundstage has also opened up a lot, and imaging at higher volume is much more distinct. And I also hear an obvious difference between the built-in DAC and my MacBook's DAC.

 

Is this what amp burn-in feels like? Because I have never heard any portable amp that does this.

I recommend getting a heatsink for the DACport LX. That way it will last a lot longer. It gets really hot and that can wear it out in time. I use a heatsink and its almost cool to the touch now :).

Because of this I am putting the UHA-6S back on my list.beerchug.gif

What heatsink?

I've been waiting on one of these forEVER (as a gift, absolutely nothing to do with Nick), and in the intervening period, I've tried several portable DAC/amp combos, among them the Meier Audio PCSTEP. The sound from the PCSTEP is something like what I imagine the UHA-6S Mk.II to sound like. Has anyone compared the two? Just curious.

No, seriously, it's a drastic change. I still can't believe what I'm hearing. Even Pandora's horrible digital artifacts (caused by the fact that most of their music are compressed unless you pay) are completely gone. All that's left is just the music, and a fuzzy image instead of an overly digitized one. But the fuzzy image is much better than the digitized one to my ears.

 

Here, this may demonstrate the point better:

 

 

The image on the left is how I feel the OPA209 presents the sound, and the right is how the OPA627 presents it.

 

The left side has good contrast, sharpness, and accuracy, which is very much true to source, but as it's blown up in size, it starts to strain my eyes (ears) and looks unnatural. It just isn't high enough in resolution, and the OPA209 doesn't do anything to increase that resolution.

 

The right side has a darker, smoother feel, with slightly less contrast, and maybe slightly blurry details (but all of it is still there), but it's easy on my eyes (ears), and it doesn't look bad when blown up in size.

I remember reading a review saying the UHA6 beat the Stepdance (the bigger brother of the PCStep). Sorry can't remember where...

I'm getting a UHA-6S MKII in a couple days and I have a question. I'm coming from usage of a Digizoid Zo and I was just wondering what I can expect, difference-wise. I realize the Zo is considered more of a bass-booster than a "proper" amp, but I notice a wider soundtage when leaving it on the lowest setting (green) and I sometimes use it for that effect.

 

The headphones I will be using with it are Futuresonics Atrio (first model...these have survived as my backups for about 3 years now), Brainwavz B2 and TDK BA200 (should be arriving around the same time as the Leckerton). Since all three are fairly distinct (bass monster, analytical, warm and sweet), should I just expect the Leckerton to simply enchance their strong points and basically open things up? I'm especially curious to see what it does to the Atrios (the lowest setting of the Zo works kind of nice on them, with no bass boost).

 

Thanks!

 

Edit: Ordered with the standard AD8610 Output.

Most definitely. In terms of amping I don't think the Digizoid compares. I ended up returning my unit as it didn't offer me anything over my UHA4 for that matter. Plus the UHA6 is a nice upgrade over the UHA4.

Tbh, I was happy with the Zo for a long time and widening the soundstage, but then I tried listening to my players unamped and realized I was actually missing details when it was on. Which wasn't good. It will also be nice to have an amp with proper line-out (the first Zo has no volume control).

I'm not sure if its been discussed previously, but does anyone know if there's any mention by the manufacturer about whether or not turning the battery charge switch on while listening through a USB connection diminishes the sound quality?
post #1500 of 2097

Well I've had my UHA-6 MKII for a few weeks but haven't given it much serious listening time.  I got a mini to mini OTG cable and finally got around to using the Leckerton with my GS3 today and the UHA-6 picks up tons of interference.  Its ok when just music is playing but if i use the phone for anything else (which I usually do) it is unbearable.  I am surprised I haven't heard of this issue if its common.  Anyone else have this problem? :(
