Read the specs on the website. Leckerton gives you all the details. You get a lower noise floor, some tweaks to the overall design, I think better volume control for sensitive IEMs, & a significantly smaller form factor. You can also roll Op-amps on the older model FWIW.

Thanks, your right about the website.  I did read it and this thread.  I am hoping for more impressions from folks who have had both and after the upgrade if it was worth it from a listening point of view.  The form factor is definite improvement.

Rolling op amps is a nice option. My Marilyn amp  is op amp rollable although she doesn't sound as refined as Sally or Itoru I can make her sound completely different at a snap of a finger. I'm really leaning towards getting the MKII because I'm curious what can be done with it. Oh by the way lee be careful which opamps you choose. The guy who made Marilyn for me said some opamps couldn't be used with her because they caused the circuit to be become to unstable. I'd check with Nick before buying to many op amps.

Yeah I'll do that. I may just end up ordering them from him in that case. But if not I'll be sure to get his input before purchasing. I mean if I can get them for a significant amount cheaper from trustworthy sources then I'll bite for sure.

Can I get this Op Amp anywhere that is noticeably cheaper? Not sure where to look.

Mouser perhaps.

Hmm, I don't know.  It's used and the ones for the UHA6 are just a big single chip w/o a module.  Price wouldn't hurt and might be worth a try especially if the seller will honor failed units w/ returns/exchanges.  Email Nick w/ that one.

post #175 of 2201

Will do thanks man. I mean at $50.00 from Nick its a bit pricey if you know what I mean. I paid $20.00 for OP 209 and that was already pushing it...

Remember that if you got SOIC8 opamp, you need to get DIP8 adapter and solder them up yourself.
post #177 of 2201

Thanks for that Clieos. Maybe I can contact these guys selling these OP amps and see if they can attach it to that particular adapter.

I wouldn't characterize the 209 as having a treble emphasis, since there isnt more treble volume or boost. The Hisoundaudio mini player I have is treble emphasized. Compared to my source HO and other amps I've owned or own, the amount of treble is the same but the difference is that the clarity and transparency around the treble detail is greater, allowing you to hear through everything more easily, if that makes sense. For instance, the treble if the k3003 isn't emphasized on my uha-6 over straight from the iPhone, instead it's smoother and more articulated, I think, due to the cleaner signal. jm2c.

That could be the cause but I still see it as brighter regardless. Not saying its a bad thing though. I actually listen at a lower volume than I would with Op Amp 8610. Just as I find Op Amp to add clarity/emphasis on the mid range I find Op Amp 209 to add this clarity/emphasis on the treble). 8610 has more depth to the sound but the sound stage is slightly smaller (it takes you deeper into the recording) while Op Amp 209 has more transparency and spreads the presentation more out.

Sounds fun. You have me tempted to try a couple of different opamps down the road.
