New Leckerton UHA-6S MKII Portable Headphone Amplifier Announced (Update User Impressions Added... - Page 104

Toslink is better than USB, and from my brief test, I can tell that coaxial is slightly better than toslink (probably because I have a crappy plastic optical cable), but... I must admit that there are better DACs out there that the amp section of the UHA-6S Mk.II can accommodate.

 

For instance, I have a Fiio D3 (the first generation one with Wolfson DAC) that I think is leaps and bounds better than the built-in DAC of the UHA-6S Mk.II in imaging, soundstage, and bass articulation. But it's cumbersome to carry around... as I need a separate USB cable for the D3 since it's USB-powered, plus I need the optical cable and an RCA interconnect as well. For all it's worth, UHA-6S Mk.II + an extra optical cable is much less crazy to lug around.

 

But honestly, I'll echo what some others have said here: if you're looking to get the most out of the UHA-6S Mk.II, it's best to couple the amp section with a better DAC.

 

But both the D3 and the UHA-6SMk2 have coax inputs, so that a USB to SPDIF adapter could theoretically work in both scenarios.  Is it the relative size or cost of the converters and/or the flexibility of the coax vs. Toslink cable in a portable configuration?  What am I missing?  Simple choice on your part?   

 

Do you have any experience with the Cirrus CS8416 DAC chip in the newer D3?

Yeah, it was a $27 DAC. They don't make it like that (with the Wolfson chip) anymore.

In a portable configuration, I'd want to carry as little as possible. Lugging the D3 along would make the rig "transportable" rather than "portable". I don't wear baggy jeans all days of the week, so the most I can afford is to have the UHA-6S in my back jeans pocket and my iPhone or Galaxy S3 in the front pocket, connected with a sufficiently long 3.5mm cable. Note that I can't use the optical cable that often because some devices I own (like the iPhone) just doesn't support that output.

 

I haven't personally heard the new Cirrus chip, but most people who have have said that it's worse than the Wolfson one.

Actually I'm more interested in a USB to SPDIF adapter and coax cable to the Leckerton, in lieu of the optical cable connection.  With a Galaxy S3 source, that should be a portable setup, too, right?

 

I'm thinking about getting the Meizu MX 4-core phone as a straight SPDIF output source, if they ever come out with a USB-serial bridge controller device for it.

Put some light on these which configuration is suitable: AD8610ARZ, OPA209AID, AD797ANZ, OPA627AP.

When in doubt, just get the 8610.

I have tried several different opamps and I find the 8610 to really work well with just about any combination I try it with.(source, iem, etc.)

The 627 can sound a bit "bigger" and smoother to my ears with certain combinations. But not most.

The 209 are supposed to be very neutral/clear, but are more prone to interference. It's what I have and I like them a lot, but I wouldn't recommend them if you're going to be using the amp near your phone.

+1 on that, I use mine with my Classic so it's not an issue

I had the chance to demo the Schiit Magni and Modi stack today.

 

The DAC was better than whatever comes with the UHA-6S Mk.II. But as soon as I switched to optical, the playing field was leveled, and the difference became less pronounced.

 

However, the Magni wasn't a match as an amp, even though it is technically more powerful. The amp section of the UHA-6S Mk.II is just so darn good.

 

I had the OPA209 plugged in today since I've enjoyed OPA209 more with a recently-acquired mellow/slow ATH-W1000X. So once again, the OPA209 proves to be quite a capable performer.

Where can I get a USB charging cable for the UHA-6S?

It uses the same USB connection as most any current phone, so you should be able to pick one up at most any store or online (Amazon, Monoprice etc.)

Forgive my technical naivity, but can I connect my ipod classic directly to the uha6 without using the headphone jack?  If so, what with.  I'm going to be ordering one soon.

You would want to use a "line out dock" such as the one pictured below.

You can connect it through the headphone jack but then you would be using the iPod's amplifier in addition to the UHA6 amplifier (double amping). If you use a LOD (line out dock) such as the Fiio L3 you will bypass the iPod amplifier to avoid double amping. Technically the sound will be better using a LOD but I don't hear much of a difference.

Thanks.  That makes things clear.
