New Leckerton UHA-6S MKII Portable Headphone Amplifier Announced (Update User Impressions Added... - Page 97

post #1441 of 2155

mine will be shipped tomorrow.

Received my UHA-6S MKII (OPA209) today. I'm very pleased with the sound. Its not very loud, high gain isn't as loud as low gain on O2 but its enough for my Paradox headphones. The DAC section is very good (using USB), nearly indistinguishable between the ODAC.

Edit:
Where can I buy the AD8610ARZ opamp?

Enough for your Paradox huh? That's interesting, how far do you have to turn the volume up and have you compared it against any other amp? I only ask because I was very interested in the UHA-6S at one point for use with a pair of Mad Dogs but a few people steered me away from it (mostly saying it'd be listenable but not optimal).

I agree that it is not optimal but it suits 90% of my needs. I prefer using the O2/ODAC with my Paradox. It has more volume headroom for recordings with high dynamic range and movies. I sometimes use EQ and DPSs like Isone Pro; the UHA-6S doesn't have enough volume for this purpose while the O2/ODAC provides more than enough volume even on low gain.

My UHA-6S volume pot is at 12 o'clock on high gain when listening to mainstream recordings. When listening to high dynamic range recordings (Eg: Hotel California by Eagles from HDtracks, ) or watching movies the volume pot varies between 2 o'clock to almost maximum volume. For comparison I rarely ever turn the volume past half on the O2/ODAC on low gain.

I use them with Mad Dogs right now. I would say that O2/ODAC drive them better, but they sound mighty fine out of the leckerton as well!

Taking a look at the specs, the Leckerton UHA-6S seems like it has a limit on how much current it can deliver into low impedance load, so I wouldn't be surprised that it's lacking current when driving the Mad Dogs.

 

The O2 has ample of current from specs (613mW into 33 Ohm vs 55mW into 32 Ohm on the UHA-6S), so I don't doubt that it can push the Mad Dogs with ease. In fact, I'd say go O2 for the Mad Dogs since it has more headroom in case you want to use EQ or DSP.

 

Maybe that's why people have been saying the UHA-6S would be okay but not optimal?

Can anyone offer a comparison between this and the Audioquest Dragonfly or the DACport LX?

post #1448 of 2155
I've heard the dragonfly, and its a nice sounding USB STICK. But I felt it paled in comparison to the Leckerton.

I haven't heard the DACport.

Well if you feel that way then I'd say the same regarding the dragonfly. As I felt the Leckertons DAC paled in comparison to the DACport LX.

The charge LED (back LED) on my UHA-6S.MKII stays on even after I unplug the USB cable. I have to flip the charge switch off in order to turn the LED off. Does anyone else experience this?

Mine does not do this (I just tried it to make sure).

No issues with that here. Mine turns off when unplugged

Mine does,

 

I thought it was normal, but aparently isn't

 

still, nothing seems to be malfunctioning, and I'm enjoying it a lot
