the op-amp transplant has transformed the sound of my e5. the top end spectrum has returned! still not sure if its better than the headphone out of my classic but time should tell.
much happier with this little amp now.

Meh, should have gone with some other seller. Ordered from Focalprice 14 days ago - shipped 13 days ago. Didn't arrive yet.

Is there a thread or can you supply info regarding this? I tried numerous searches but did not find specific details.

The e5's top end is indeed a touch dark, but nothing serious IMHO with the combos I tried and actually a bit "euphonic" in character. Depends upon your system synergy, I guess.

 

[GaryPham]

has anyone here used an E5 with an HD485? If so, what are your opinions?

 

[nttg]

How does E5 sounds over time while it gets burn in?

 

[dfkt]

There really aren't any components in the E5 that require burn in.

Hi Johnny, do you have pictures of the transplant? Was it difficult? There isn't much room in the little E5, and it looks difficult to get apart. Please post your thoughts and pix if possible.

thanks,

E5 has been taken apart quite a few times before and those pictures were buried under this thread somewhere. The 'transplant' requires some pins de-soldering / soldering on the SMD based opamp - not an easy job to do unless you are good at soldering and own a good soldering iron with small tip.

[EDIT] Also, AD8620 doesn't really design to run on low voltage like the original opamp, so it will only have a very limited run time and under perform all the time.

Excuse the possible silly question here, but can the E5 be used with RCA line outs of a home preamp/processor as a headphone amp?

I have an Emotiva MMC-1 pre/pro with no headphone jack output. I know a dedicated headphone amp designed for this use is the best way to go but I was curious if anyone tried this and what the results would be. BTW, I'm using Sony MDR-7506 headphones - perhaps not pertinent to this question but doesn't hurt to throw it out there.

Here's a link to the MMC-1 manual. Not much info given as far as output specs.

Thanks in advance!

Does the E5 have the same (rumored)problem as the E3 in that it will burn out the crossovers of dual or triple driver IEMs?

I don't see why it won't work, though I would imagine the SQ won't be as good as a proper headphone amp.

If it does, it would have burn out my q-JAYS, UM2, TF10, and SE530 by now.
