They are a little lower than the Muses opamps, so just a little grinding you will be able to close the case.

Right now Im just running some experiments on music quality, thats why Im running 2 LT1010 in parallel per channel. 

 

REgards!

Are you sure? The LT1010 I have are the same height as the MUSES. It is the BUF socket that is lower, mainly due to how the PCB is designed.

Mine uses the same socket for buf and opamp, the dif is minimal, take a closer look to the legs of the Muses (right) and LT1010 left,   probably a 1mm diference on the leg, that makes Muses sit a little higher that the LT1010.

Yep, I checked the legs, they are also the same, certainly much less than 1mm, more like 1/4mm to me. But I can imagine that small difference can be between a fit and non-fit in a very tight case. I am lucky that mine clear the case without a problem, but it is pretty tight as it is. Another 1/4mm then I might not get them to fit at all.

Yeah! 1mm is too much made a mistake (Lol), I think 1/4 mm is the diff as well :biggrin:

If you look at the the metal body of your case, do the big flat surfaces that form the front and back exhibit a kind of bulging or barreling? Mine does.

If you look where the end caps meet the body, the metal at the center of the flat surfaces bulges up slightly at the center, and runs the full length of the amp down to the other end cap. You can see that the metal is not flat, but bulges along the length of the case. The effect is that the body sleeve is more towards a cylinder than a perfectly squared box. If you press on the bulged center, it becomes flat, but bulges up again once you release it.

I wonder if this minor defect is what's providing enough clearance for the Muses? If so, how fortuitous!

Incidentally, I have two standard E12s in addition to my E12DIY. Only one of my regular E12s has perfectly flat surfaces. It looks very tight and of very high quality!

My other E12 and my E12DIY have the bulging metal. It's slight and doesn't affect the performance, but it doesn't feel as nicely put together. You can especially appreciate it when light reflects off of the case and you can see the metal is not flat but slightly curved. It feels slightly cheapish to see the surface is not flat as one would expect it to be.

However, I hope this defect will allow me to install Muses in my E12DIY without the grinding step.

My case is near perfect flat, as far as I can tell. I think it is just an issue that the case isn't originally design to accommodate DIP8 (or more precisely, socketed DIP8) and a re-design will add cost. Would have been nice to know early on that DIP8 might become a problem and ask FiiO to sand the case down for us during the case manufacturing. Well, if E12DIY ever has another run or something similar in the future, I am definitely going to make that suggestion. But as it is now, I think it is mostly luck whether the DIP8 opamp or BUF will clear the case or now.

Interesting. Mine is perfectly flat. I can also use the Muses 1 and 2 without modifying my case. Great little amp.

Have you listened with the HD650? Can it keep step with the SR71A or PB2 with some of those harder to drive, over ear headphones?

I briefly tried my T1s and my HE-500s and the DIY did well. Not quite as authoritative as a desktop and I can't compare to either of the amps you mentioned, but I was happy enough with what I heard.

post #896 of 1941

Further to above, I just had time to do some further testing and can confirm that the DIY drives the HE-500s and T1s extremely well for a portable amp. When I mentioned desktop amps I was talking about the Bottlehead Mainline as my reference which is really not a fair comparison at all. The DIY would sound as good or better at driving the T1s as the Matrix M-Stage I recently sold. Plenty of power, plenty of space in the soundstage and good detail and separation. On high gain I'm running at around 10 O'clock on the volume using an RWAK100 at 100% volume as the source.

Well, changed some caps today…

I came back to  the BG-PK, the closer was SILMIC 2 bypassed by some Panasonic 0,01u metal films (even bypassing there was a mid bloat.. everything got confused).

The PSU was changed as well, some low ESR Sanyo OSCON replaced the stocks (did a mess and a trace was lifted for one cap, had to make a new trace - the one that is kind weird).

This little thing became my fav portable amp… I wish I could tinker more on the LT1010's 

 

post #898 of 1941

That's why I don't want to change with the PSU caps. Very likely will mess up the trace if I do.

I've beenbusing my diy for some time now with my ie80 and I have to say I am falling in love with adele all over again....
My setup is wolfson s3》e12diy》ie80/xba3/momentum/hd518/xba-h1...

The Black Gate nonpolar caps settled in well with my 12DIY. Transparent and great transient response.
