the problem with 0404 is you can't change the opamp used within. while for D1, you can upgrade the opamp for better sound or find 1 that suit your taste best...

Has anyone used the AD8599 as a buffer?

Well I wouldn't be changing out any opamps...what I buy is what I'll be getting

That's unfortunate...

Where can I buy OPA627BP? None of the places I searched (Newark, Digikey, Mouser, etc. plus other places I googled) has it. Yes, I did see the ebay listing that wants over $51 a piece plus shipping. I'll pass that one.

Thanks.

I recommend a buffer of fairly high power. AD8397 sounded very nice with the 627 in the 2-1 adapter. You could also use the LMH6643 and lose just a bit of impact and boldness.

Yes, but it works better in LR. I like more power and higher slew rate for buffers. AD8397 and LMH6643 are hard to beat for buffers if you need to drive low-impedance phones.

For higher impedances and especially if they are pretty efficient phones, the LME49720 is a very nice sounding opamp buffer. They have limited output power though.

Ron, using the LMH6643 as a buffer what type of sound to you get w/ the AD8599 in the L/R versus the OPA2111 in the L/R.

This weekend I am thinking of using the OPA2111 and the AD8599 in the DAC. Have you tried it? I also wonder if using the AD8656 in the L/R would yield a nice sound while using the LHM4562 or the LMH6643 in the buffer.

While doing the above experiments I may try the AD823 back in the L/R using the LMH6643 and the LHM4562 as buffers.

Maybe we should get together w/ Vorlon1 to try those combinations.

The AD8599 sounds quite good in either LR or DAC. Not as dramatic a soundstage as 2111, but nicely balanced and clean.

If you use the AD8656 in LR, you will hear one loud pop when you turn the amp on, then you throw that opamp away. It is rated at 6 vdc while the LR socket outputs about 8.3 vdc. The pop has a nice wide soundstage with lots of detail though!

go with the D1...

i once own a 0404 usb.. the headphone out is not that impressive...

Has anybody tried the Macbook Pro to iBasso d1 to HD650?

Impressions?

Macbook > iBasso D1 > HD600

Does that count? If so, it is highly recommended. The iBasso makes for a great DAC on the Macbook (optical or USB), and with rolled opamps it gets even better - it goes from great to outstanding.

I did a test of the inexpensive but good Headstage USB DAC and compared it to the iBasso. They both improved the sound, but the iBasso stood above the crowd (at 6x the cost it better be better). http://www.head-fi.org/forums/showth...5&goto=newpost

Wow I just learned that replacing OPAMPs doesn't require soldering. If that's true...then yeah I'ld be up for changing out OPAMPs.

Wow, thanks for huge responses.
Yeah, I've been wondering, should I change the LM4562 to AD8397, and even change OP2111 to 8066, this is jamato combination is it?

AD8397 in my SMIII sound quite fast, big, but I found cymbal sounds sometimes hurt my ear. So today I change it to LCT6421, so it sound much warmer, although the bass slightly less noticeable?

I've tried LCT6421 (LR) with OP275x 2 (BUF) and AD8656 (DAC), the result... everything become so mellow... not energetic at all. I guess this is not my type eh?
