Yes, it would seem you would want to be very careful.

Any concern that it will be too thick for the E12DIY tight spaces?

I believe ClieOS and others have indicated that the dual-level soic-to-dip adapter will be too thick to fit into the case once you get the chips on. You will have to use that side-by-side adapter, I believe.

I think one of those side-by-side boards came with the amp. Not sure where you'd get extras, though.

There are three side-by-side dual SOIC blank adapters, three single SOIC blank adapter and two TO220 / DDPAK buffer blank adapters included. They are underneath the foam pad that houses the stock opamp / buffer. Just take out the foam and you will find them.

 

You pretty much won't find much use for the extra buffer blank since most other alternative buffer don't come in TO220 / DDPAK package. Single SOIC blank adapter can be replaced by using BrownDog single SOIC adapter. I won't recommend buying cheap single SOIC adapter on eBay as none of them has the right slim rounded pins that can fit on the rounded DIP socket in the E12DIY. I have found out that, unless you are in the U.S., round pins are very difficult to find and often not cheap. You will be better off with the real BrownDog. As for the side-by-side dual SOIC adapter, they are only made by FiiO specially for E12DIY. For those who used up all three, try contact FiiO and see if you can get more from them, probably for a fee. You can custom order them from many PCB maker, if you are willing to pay the high cost.

Inside E12DIY: OPA627

1st row (from left): ADA4627-1, OPA1642, AD8599

2nd row: NE5532, LM4562, LME49720, LT1358

3th row: LT1010 x 2

Still got a few more I need to mount when the BrownDog adapters come, namely LME49990, HA-5002, LT1469, and LME49860. Might also order a few more opamp by February but I am not sure yet.

MUSES

 

Oh, I didn't know there are fake MUSES8820s on the market.

Here is some photos of legit MUSES8820.

All MUSES op amps I have seen have two capital letters on the back.

The font face of the fake one looks a bit thinner.

The width of "E" is too narrow.

The shape of "0" is too oval.

Your MUSES01 and MUSES8920 look legitimate.

I guess your MUSES02 and MUSES8820 are actually NJM4580.

Are you sure?

Which shop did you buy them from?

 

I only know three authorized resellers.

http://akizukidenshi.com/

http://eleshop.jp/

http://www.chip1stop.com/

 

I think these shops are only sources for individuals.

MUSE02 is priced 3400 JPY, MUSES01, 3500 JPY.

MUSES8820, 400 JPY, and MUSES8920, 480 JPY.

It's impossible to get them at lower prices here in Japan

unless they are used.

 

There is some shop in Mie prefecture that sells fake MUSES op amps on the net.

Like this.

http://item.rakuten.co.jp/shinyou-toukai/10000079/

http://item.rakuten.co.jp/shinyou-toukai/10000080/

But this shop is no authorized reseller.

 

No offense, but I'm pretty sure your MUSES02 and MUSES8820 are fakes.

The top surfaces of them have been ground.

MUSES02 and MUSES8820 look different from MUSES01 and MUSE8920

in the photo you took. It's odd.

 

I'm gonna put some photos of NJM4580DD later.

Here you are.

I have 12 pieces of NJM4580DD.

I found one with two capital letters on the back but

the others have one or two small letters.

Of course, I can't assure you that all MUSES op amps have two capital letters.

There might be some with small letters on the back.

the muses series are too expensive otherwise we can put it into E12DIY, at the other hand , or the OP / BUF included in E12DIY is came from original factory so you don't need to worry about it is fake or not, I known there are some fake audio op/buf in China.

Didn't buy them myself. They come from Elekit as part of the review samples. Elekit uses MUSES8820/8920 on their portable amp so I assume they got their opamps from reputable supplier. I do remember the MUSES02 came with the similar package as the one shown on akizukidenshi.com. I guess the only real way to know is to put them under x-ray...

Or to compare to a known Muse of absolute true origin. If no sound difference is heard either they are both fake, both real or one a fake, and the fake is very good so it doesn't matter. :^)

True. I'll probably order some JRC opamp from akizukidenshi.com soon, might as well adding the MUSES in my shopping cart given how cheap they are in Japan. Have to order JRC opamp from Japan anyway since no local dealer is selling them and ordering from U.S. just isn't feasible due to the high shipping cost.

post #600 of 2221

guess I was couple months late to the thread. After no having the opportunity to get the first rev.1 of E12 with sub bass boost, I'm wondering if these DIY models can be customized to get the bass boost at the user preferred requence (50hz or 80hz or 100+ hz). I've been in and out of these threads, so please let me know if I'm clearly missing some key concepts. The other question is if the DIY will ever be redistributed?

 

THanks
