You can try opamp rolling in the DAC section too, and diamond buffer should get rid of the slight metallic sound which can happen between HA3-5002 buffers and some Analog Devices opamps. A better power supply would probably help the sound too. So there's still a few things left to experiment with.

Just curious, is there room in a PACE for the amp, dac, battery board, and diamond buffers, or do you just have to pick three to make it fit in the case?

on a normal hammond case(the common one) the diamond buff wont fit, the transistors get in the way with the DAC.....unless you get a longer or taller hammond.

I believe that all of it can fit the standard enclosure, according to Larry, if some components are installed bent. I have a buffer now but not the amp so I can't tell for sure myself.

 

[xtreme4099]

im talking about with tangents battery board ...

 

[aos]

I was under the impression that it would fit normal case even with battery board. I guess Larry is the only person right now that can answer that question but that buffer does look pretty tall.

 

[xtreme4099]

hmm... maybe he has gotten them to fit ... ill askem about it this weekend ...

I went with the Larocco PPA Deluxe w/Diamond Buffer and AOS DAC. Can't wait for Santa to bring the little beggar!

Originally posted by Jon Beilin As a headphone amp, the PPA is a great choice. Lots of details, highly dynamic, large soundstage, very musical. Some might say it has slightly metallic highs but it's not bad at all. What is very attractive is opamp rolling- one literally can almost completely customize the sound of the amp. I found putting the AD8610 in the l/r channels and the OPA627 in the ground channel to be a great combination for a very solid sound for all types of music.

well... reassuring... seems that i am no longer alone with my preference of the ad8610/opa627-combo in the ppa (even without diamond buffers)...

I wasn't using diamond buffers and loved the opa627/8610 combo in my PPA I just recently sold.

Are people mainly using the 627 in the ground position and 8610's in the other two positions? Or the other way around? *Can* you use the 8610 in the ground position? If I am wording that wrong I apologize, not sure on the technical jargon here. I went with 627's across the board as I tend to prefer a smoother (tube-ish if you will), even a hint darker presentation as I hate any sort of tenency to brightness or the like. I had a Emmeline XP-7 for a brief time and personally much preferred AD797's in it versus 8610's which I found were a bit too bright-ish for me. I'm willing to try an 8610('s) in my PPA, thus my questions.

 

[dngl]

yeah it's mainly 627 in the ground, 8610 in l/r. You can do a 8610 in ground, 627 in the other positions as well, but 627 on ground is my preference.

 

[BrokenEnglish]

yes.. opa627 in ground, ad8610 in l/r. i have a little problem with this combo: when the phones are plugged in and the amp is playing a while, it is not possible to switch it on again after a short off-period (< 2') without unplugging the phones. has anybody similar experiences?
