Yes that's me! Awesome little amp/dac. Still haven't been convinced to try anything else. And I've shopped around!

You are absolutely right, it reminds me of the EX1000. They are hype free. wink_face.gif

I've got a set of UM Merlins I sent off for a refit, and I'm looking to have an amp in-hand to drive them once they return.  I think this amp is the winner, just have to decide on the op amp...and keep watching for used ones...

Welp.  Just jumped on the ADA4627 hype train.  Let's see how these will pair with my 1964 V3.  The OPA627 and V3 didn't get along that well with a lot of buzzing noise especially at low volume.

Looking forward to your impressions.  I'm between the 4627 and the 8610; another positive review of the 4627 may just be what it takes to make the decision for me.

Considering I'm the one who started this thread back when the UHA 6S MKII was first being announced I'm pretty impressed the thread is still alive and pushing 100 plus pages. It's good to see the Leck's are holding their own on this forum against other pricier gear. Speaking of Leck gear I'm actually contemplating of just going with my UHA6S MKII and throwing my UHA4 with op amp 8610 up on the FS forums. Haven't really made up my mind though.

Well it's no surpise to me. Leckerton makes quality amps. From the UHA4 to the MKII :).

If I wanted to change my opamps, all I would need to do is purchase the "SOIC-to-DIP Adapter w/Pre-Installed Op-Amp", take apart the amp, pull out the previous opamp, and then put the new one in? I'm interesting in grabbing a 4627 to go with my UERM and hd600.

This an impression from someone on another forum where he compares different opamps used with his uha-6s mkii, it was really helpful for my decision to get the 4627!

"Posting my recent opamp impressions:

4898-weighty, thick, and rich, maybe not as much as 627. Organic sounding. Better blackground, than 209 but less detailed/resolving, less plankton. 209 digs deeper. Vocals less dry than 1611 but still a hint of dryness. A bit muddled at times, but still decent separation. Slightly bigger sounding bottom end.

209-Analytical signature, digs deep. Easier to hear recording noise and artifacts. String plucks and applause is more thin and brittle. Slight haze/veil despite picking up tons of detail. More blended, less separation and articulation of dynamics. Overall less refined signature than the others. Vocals less dry but could also because it stands out less in overall signature which is more coherent and balanced than the others. Therefore, any vocal issues could stand out/apart less. I do think vocals are more liquid than the others in actuality on more listening.

4627-Better dynamics and note articulation than 209. Perhaps best macro and micro dynamic balance of the bunch w/ lots of clear inner detail. Excellent timbre! Clearer, blacker than 209 w/ better separation and imaging. Widest SS of all. Less recording noise emphasis than 209 but actually more resolving. Superior resolution, excellent spatial precision, best blackground, fantastic macro and micro dynamics. Most natural and accurate timbre. The clear cut overall winner.

1611-Very fast, best of the bunch. Analytical type sig. Decent timbre, not as good as 4627 or 4898 though, better than 209. Not sure why, could be a minute extra bit of treble brittleness, ringing type treble sound. Driest vocals. Wider SS than 4898. 4627 has cleaner, clearer note articulation and more accurate timbre. 1611 might have sharper, more precise sound but less blackground and timbre is less accurate and fleshed out.

Note: All opamps have more than sufficient run time w/ the exception of the OPA1611 which has the fewest by far."

Is the AD4627 susceptible to mobile interference?

I'll go check later and see. The 209 definitely has a lot of interference though...
post #1753 of 2193

Thanks! That's why I opted for the AD8610. If the 4627 isn't, I will HAVE to give it a try biggrin.gif

Anyone here know where I can order an op amp storage tray/box? I'm getting tired of storing my opamps in the little cardboard boxes Nick sends them in. I tried searching mouser but it's taking forever for a search to complete on that site.

Couldn't you just use one of those clear-ish plastic boxes with a ton of compartments that people use to store beads or buttons or jewelry?

Unless they need to be stored very specifically (I have no idea), you can get one of those boxes with like 10-20 compartments for under 5 bucks.
