I got a mail from them and they told me it would be shipped out on monday.I rather not wait for the new opamps as I could do it my self.I am sure the new one would come at a far higher price than what it would cost you to do it.

Changing opamps does not violate the warranty.

My sort of thinking too. I enjoy tinkering and even if the D1 shipped with improved op amps who is to say that they would synergize with your tastes or cans? Plus there is still a lot of research going on as to what are good opamps to try.

When did you order? I placed my order on the Sept 16th - it would be great if my D1 were shipped early next week too.

I want to thank mrarroyo, jamato8, and HiFlight for their continuous suggestion of possible opamp rolling combo for D1. I ended up collecting quite a few of different opamps now. But so far, my absolute favorite opamp combo for D1 is OPA2111/LM4562/AD8656 and I believe this combo was first suggested by mrarroyo. Thanks again for suggesting this combo for us mrarroyo. This combo is sounding so good right now to my ears, I am not so sure I want to swap anytime soon.

Thanks, but it has been a team effort. HiFlight and Jamato8 just to mention a couple have added far more than I. The thing is there are so many combinations that by having a few of us trying different op-amps it makes it a lot cheaper and quicker for all of us to get a better sound.

I like the way the iRiver is contructed and the quality feel.

I have the iRiver 120 now velcroed to the top of the D1 with the optical cable (a very short custom one from Syscon in Canada) and it is a great combination.

Thats the way to go portable! Or at least the way I understand "portable". Some people consider laptop as portable.

Anyway, how could you survive without rockbox? It makes iRiver different beast altogether.

Be careful with dropping 40G drive into H120 - from memory, when I was active on MisticRiver - H120 case is a little thinner than H140, might have trouble to fit it in physically in. Again, I would double check it on Mistic forums.

And good luck finding H140 in good nick - they are getting quite rare nowadays.

Has anyone tried AD8620, which is used in SuperMicro IV?

I am not sure that the Micro uses that opamp, but yes, I have tried it in the D1 when I was trying to determine which opamp combos to make available for upgrade. It was OK, but I didn't care for it as well as some of the other choices. Other individuals may like it better than I do.

I felt that it didn't really have as realistic soundstage and imaging as some of the others, and this, IMO, is as important to realism as tonal accuracy, if not more so.

I'm currently using it, along with LM4562s in the buffer slots.

While this combination is a noticeable improvement over the stock D1 configuration, I'm eagerly awaiting some of the other op-amps that HiFlight and jamato have been rolling.

HiFlight · Oct 12, 2007 at 11:08 PM

I found an opamp that is an upgraded version of the LM4562. Personally, I didn't care as much for the 4562 as some other buffers, but the new LM4562 replacement opamp is warmer, with a much improved soundstage. It works really well as a buffer.

I am using the AD746 as L&R amplifier and the LT6234 as the DAC opamp.

For those already using the opamps that I have been testing over the past several months, there are several good options that one can combine with the new buffers.

I liked this new setup so well that I ordered a bunch of the new opamps while I could still get them.

For further details regarding this combo and options, drop me an email or PM.

Hmmm, the phrase "D1 max-out" has a ring of finality to it.

So Ron, is this the magic cocktail, the whole enchilada, the Holy Grail, the ONE???

Or does the quest continue onward & upward?

Your adoring public awaits...

Best, Dex

While I am very pleased with this combination of opamps, undoubtedly the quest will continue. Not so much for new opamps, but for synergistic combinations of the ones previously tested and mentioned in earlier posts.

Even though a particular combination might sound very good to me, other combinations will no doubt sound better to another. So there will never be a "Best" or a "Final"

I probably have more opamps on hand now than I should. This project started out small but has grown as I have discovered additional opamps that do justice to the potential of the D1.

Monster_Omelette · Oct 13, 2007 at 5:17 AM

Are there any good DIP opamps for the DAC of the D1? Just wondering since I have no experience soldering anything and I don't have a proper working space to do that kind of stuff.

yuheng · Oct 13, 2007 at 12:12 PM

i just wondering, no body try to put 4562 as DAC/AMP opamp rather than just buffer..
