FiiO E12DIY Limited Edition Version---DIY your own sound ! - Page 58

post #856 of 2028

I like the opa 1611 and the buf634. Great that they included the opa1611. Great little amp.

Just wondering whether you have had a chance yet to compare - not looking to rush you though -smily_headphones1.gif

I was hoping for answers to the following questions:

1. In general, how do the 3 buffers that come with the E12 DIY contribute to overall SQ?

2. What are a few opamps that I could order that are plug n play with no soldering and no case grinding/sanding, and what's the best source to order from?

3. No access to soldering equipment and no friends who are into DIY electronics on my end. Is there any interest out there in providing that service for people like me? For instance, you order some opamps which need to be soldered onto the E12 DIY's adapters, and we send you our adapters and compensation for cost, time, and shipping?

Thanks,
Nikolaus

In relation to Q2, I don't think there are any because the DIY uses an 8 pin socket, but DIP-8 chips are too tall. Some slight sanding or filing work is probably the easiest option. Someone put some great picks in an earlier post on this thread.

OK, that's great news! Gosh, I've been so busy I didn't even take a close look at what came with the amp. Thanks!

Well, maybe I'll have to borrow my dad's Dremel tool then.  It sounds like there are some interesting DIP-8 opamps earlier in the thread.

To me, everything is just a little smoother. For example, particularly with the combo in the amp when you buy it - OPA8632/BUF634, treble is a little bit harsh with a lot of music I tried (I tested this 'stock' combination for 5 days/~12 hrs when I first received the amp) to my ears/with my setup (the IEM's I use don't exactly have sparkly treble either, and my source is black as the ace of spades). I found LME49600 puts a bit of a lid on that, and just makes all 4 opamps sound a little bit more 'controlled'. Obviously YMMV depending on source & headphones/IEM's/etc.

I didn't notice the treble specifically, but found that the LME49600 made the sound more spacious and coherent while the BUF634 sounded to me like it was pushing the mids forward a bit at the centre and it made the music seem more like a recording to my ears.

 

As always, personal taste will play a big part in which combos different people prefer.

Wow, good comments on the LME49600. I'll definitely be trying it. It's great we have a choice with this amp. What a fantastic opportunity this was. Thanks, James!

Lol, I've been so busy I didn't even register what came with the amp when it arrived. I've just been using it with the stock chips, which I like a lot. IMO, the default DIY configuration has more weight and character than the standard E12, which is very competent but a little bland in comparison.

With all this talk of OPA627, I'm just waiting for the right time to order some up. Does anyone like the OPA604 which was included with the set? I just swapped these in and it's too early for me to tell.

After the OPA604s burn in for a bit, it will be the OPA1611, and then the OPA627 once I get them.

This is being released in Japan on Friday.

Are these more expensive than the E12 because of the revision of internal circuitry or simply the additional opamps/buffers?

What do mean? You are selling your personal amp somewhere in Japan, or FiiO is producing them for the Japanese market?

 

From what I understand, these are a limited production item and no more are planned to be produced.

Both as I understand it. From what I have read, the internal circuitry is simplified and improved (thanks to removal of bass boost, etc.) and there's the ability to swap buffer, op amps, capacitors and resistors with some provided, but lots of options available on the market

post #869 of 2028

Do you guys think that it is worth the extra cash? I'm intrigued by the possibility and it seems like a ton of fun, but at $271 after shipping...wow, that's so much more than an E12.

The extra opamp and buffer themselves will cost over $50, so keep that in mind. See below:

$271 is the price for those of you who missed the pre-order. Those of us who pre-ordered only paid less than $200, including direct shipping from FiiO no less. E12DIY isn't a money making products and that's why the price can be set so low initially. But once the retailers picked them up, invested into tax, shipping and stocking fee, etc, the price does go up a bit. Then again the original pricing has no room for profit at all, so it is still sensible for a $250-ish price tag. Well, retailer have to make a living too. I personally would think a sub$300 price tag is still well worth it, regardless of what the initial pricing is, consider that it competes very well with all the $300+ amp I have heard. I said this before - If E12DIY was from a more famous Western brand, it could have been sold for an easy $350+ and buyer will still feel happy about it.
