FiiO E12DIY Limited Edition Version---DIY your own sound ! - Page 90

post #1336 of 1601


Wanted to get your opinion on the matter. I plan on cutting the chassis along the black lines and cover it with a piece of a plexiglass sheet so that the insides of the amp can be visible. I think it will look great with that blue led light. What do you think?

Should look great, but I wonder if it will affect EMI shielding or not.

I supply transparent PET sheets that are conductive and very good for EMI shielding with resistance at < 5ohms/sq inch. It can be laminated onto clear acrylics with light transmission of 80%+++

I can probably use it without the chassis for a day or two to see how much will it affect the EMI shielding.

How much will it cost me to get those sheets? All I need is a sheet of 6 by 6 centimeters in size.

We usually sell in master rolls of 600mm x 200Metres. But let me check whether I have FOC samples for you cos it is really small.

Took the E12DIY out of its chassis, turned it on and plugged some iems in. Turned the volume way up and attached it to my cell phone. Made a couple of calls while the iems are in my ears and heard no static or anything. Does it mean that even without the chassis, the E12DIY is EMI proof?

EMI also depends strongly on the opamp and buffer combination. You might get great EMI result on one combo and bad EMI result on another. i.e. one of the reason FiiO changed the original opamp oi the E12 after the first batch is actually to address EMI issue.

Think I may have hit an awesome Opamp / Buffer combination.  Running a couple OPA627 soldered to one of the blank single to dual adapters in the E12DIY kit. 

 

I personally think the OPA627 with the HA-5002's is the best thing I've heard to date and OPA627 blows the MUSES chips away by a considerable margin to these ears.  Wow.

 

Do try the OPA627.

Actually I currently have the OPA627 + HA-5002 in my E12DIY too. Though I won't go as far as saying it blows MUSES away, I do agree it is one of the really good combo.

post #1346 of 1601
Now my E12DIY is truly DIY. Took me a couple of hours to make but I'm really pleased with the results and I think that have enough space to fit inside any opamp+buffer combo I please.

I'm can promise you now that i won't be able to find a soldered pair at all, at least not with your help... If you do start that thread, be sure to mention it here smily_headphones1.gif

OPA627 is a must try. Definitely in the same league as MUSES02, IMO, and betters it in some ways.

I'm very glad to have this as an option.

What do you prefer about it to the MUSES02? The MUSES02 will cost me $136 shipped from Mouser so I'd much prefer the 627s if they suit my tastes!

How did you come to that number? Sh*t that's way expensive.
