Thanx a lot.  But there's something going on with that conversion ... namely some noise or something else  is introduced. It ain't so perfect.

Perhaps, one needs an expensive converter. That's what I've read here and on some other audio forum.

I won't buy one and am happy with that decision... what is not satisfying is the fact there are no quality compact iphone compatible amps out there when there is no technical limitation to doing it right in something the size of the UHA-4.

You seem to make an effort to be negative in your posts. Is there any particular reason?

Well, there are a few... they are just more expensive than the Leckerton. Part of the difference may be license fees (but I'd guess thats a minor part), part are additional parts needed for establishing communication, part is missing competition, part is the quite small market for that kind of device...

 

I fully understand that Nick designed the UHA-6S to be compatible with as many devices as economically feasible, i.e. without increasing costs while catering only to a minority of his target audience.

The conversion is not perfect indeed, but it's still far better than the USB interface that the Leckerton has.

When I can, I just use the optical output of my MacBook, but the other solution works for devices like the Galaxy S3 and my netbook.

i bought DacPort LX and it is a pure magic! used Optical but it does consume the battery way 3 times faster than the usb!

Thanx again.

Finally I have a full picture of the UHA-6S MKII USB subpar performance as compared to its excellent performance using an optical input.

haha, no effort necessary but i like your profile swami

I'm curious as to why you went the Toslink route instead of using a USB to SPDIF cable adapter such as the M2Tech hiFace 2 or the Matrix USB-SPDIF converter.

 

And I’m sure that everyone here knows about the potential SPDIF output from the Meizu MX 4-core phone, right?

You should design one then, since you're the component expert.

just started working on it actually...

Plugged in my HE500 in the Leckerton (usb from galaxy s3) while working around in the house, the sound coming from this little amp/dac is just amazing. Even though it don't power the HE500 to it's fullest, the sound from it is just brilliant.

Because... well, if I have to be honest, I use the DAC in the UHA-6S Mk.II only because it's convenient.

 

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.

hello guys I read on another site a poster said that the AD797
Was a better choice for the uha-6s
he said It is a BJT input stage with extra interference and distortion cancellation circuitry,
And the tradeoff is some battery life due to higher bias current.
So like to know if anyone has comments any on that.

That must be one helluva bargain. Am I right, is that a $27 DAC?
