New Leckerton UHA-6S MKII Portable Headphone Amplifier Announced (Update User Impressions Added... - Page 13

post #181 of 2187

Yea I really wanna get the 627 OP Amp since that one supposedly sounds tube like and euphoric. Right now the Studio V paired with the MKII was great but got tiring after short periods of time (too much of a good thing ;).

 

BTW yesterday I gave my FX700s another listen through the DACport LX and MKII and remember why I bought them to begin with. I had to remove them from the sale forum. They just have such an engaging yet sultry sound. I absolutely love them for very low volume listening. The imaging is second to none for dynamic IEMs IMO.

The 8610 was a bit more 'V' type sounding to me.  Could be that getting more bass bloom from the 209 to match the 8610 brings up the treble if it's cranked up more.  Have you tried to volume match the two for comparison?  Then again I wonder if you might be hearing the sources truer natures.  I did consider both DACPorts to be of the brighter sounding DACs.  Is it still too bright using the onboard DAC?

If you are referring to the Cirrus DAC in the MKII then yes I did find it to be brighter/harsher IMO and a significant downgrade from the DACport LX. So I don't plan on using it. This was last tested using the 8610. I'm finding I'm listening at lower volumes on the 209 paired to my DX100. I still feel treble presence has increased or at least it feels that way. It's more noticeable at least and due to this I do listen at lower volumes or will get fatigued. Not saying its a negative at all. I'm actually warming up to this OP Amp and may end up using it as my primary Op Amp. We'll have to see though. But yeah 8610 does has a slight emphasis on bass as well which is a plus IMO. But the mid range clarity is my favorite part about this Op Amp.

Swappable op-amps seem like a tinkerer's delight. I'm just getting into different sound signatures that headphones alone offer. Different op-amps seem like they multiply and square the possibilities.
 
Is changing op-amps similar to installing single inline memory modules (SIMMS)?

I'm not sure. But I know its quite simple and I've never done it before myself. Well I have worked with electronics in the past though and assembling/soldering. But regardless a kinder gardener could do it.

It's easy w/ an extractor or the right type of pliers.  Just be steady, slow and maintain/adjust for a proper angle to avoid bending pins.  As with all chips, always pin 1.  You can always bend pins back to fit but knowing they look bent inside the chassis would annoy me.

Just a quick question lee, when Nick sent you the op amps did he clearly mark them and send each op amp type in it's own container? When I get my MKII I'll probably order a couple of different op amps and I'm hoping each op amp type comes in their own clearly marked container.

The Op Amps come in a small box. They are clearly marked from factory but the print is super small so you'll have to strain your eyes to see the writing.

It's late over here an I got to crash so I can work tomorrow. I have Sunday off I think I'll update the first beginning of the thread with the different op amps and their general sound.

Thanks to the review and discussions here, a spanking new UHA-6S MKII is on my desk, charging up. smile.gif

So you did buy the UHA6 MKII? Wow your a big spender this month ;). Then again so am I :P.

Think the new Leckerton would be a good "mate" with an AKG K271 MKII, Beyer DT-48 circa 1985 & a B&W P5?

 

TIA - Rich

Hey what do you guys think of Coaxil and optical compared to the regular input on the UHA6 MKII? I'm actually liking the sound I'm getting via Coaxil to my DX100 plus I am able to set the amp to 0 to save battery life.
 

Just a heads up though. While OP Amp 209 is a very nice OP Amp I still prefer 8610 to it. I find myself getting tired or fatigued more often with 209. But depending on my mood I can find myself switching back to it once in a while. 8610 is where its at IMO :).

I too prefer the other digital inputs over USB and the regular input would depend on the DAC/source in front.  I'd take my PWD going Line-in anyday over using the stock DAC.  The DX100 didn't do it for me if it wasn't acting solely as a digital transport.

 

Glad you like the 8610, perhaps it has a nice synergy w/ the FX700 for you.  Not my cup of tea personally but it's good to have options especially w/ various phones.

UHA-6S MKII op-amp209 plus recently burned-in Hifiman RE-272; it's like a blanket's been pulled off the sound compared to my other IEM's. Running iPod classic - a generation or so behind the current classic seen in stores, lol.
