Yes indeed, so simple and inexpensive.

There are other op amps that may sound different, but that one is definately better than the NE5532 supplied with the kit.

Just make sure it's the right way round.

I just give it a try :-)

The right way, must be the same as the NE5532 ! ?

Anyone else tried the LM4562 ?
I did and while it sounds very good I think it lacks slam and impact, probably because it usually sounds better when followed by a buffer or at leas a resistor that isolate it from capacitive loads.

In the first pages of the thread Jean-Paul, which uses LM4562, suggest to use the resistor to improve sound.

Not much, with patience and fine solder.

Hi..

I just got my finished AKM4396 dac, and since i got the information of the dac kit from this thread i think i should share what i've experience about this dac..

my ak4396 uses "custom" Broskie tube Unbalancer as its output stage with two GE 8cg7 tube and then feed by Phillips ez80 as the tube rectifier..

i cant says much about the design of the output stage,, because i had it built by my friend..

the sound is very amazing for a dac that this cheap and small, mid and high is clear and natural without a hint of harshness and it gives an effortless feeling.. detail and sound separation are excellent.. and i'm not experiencing the lack of bass that some has say.... i have the elektor dac with all the boutique parts (BG, tantalum, vishay etc) and i think the ak4396 has better it in almost every aspect..

this ak4396 dac kit is trully a very good performer even with stock op amp output,, but once you paired it with good tube output (or maybe an OT) you'll expect a significant improvement,, imo no comparison with the opamp output..

i think ill stick with this ak4396 dac for a little while

sorry for my bad english..

regards

Default AK4393/4396

I have been listening to the stock DAC 2496 (AK4393) for a couple of weeks. Recently replaced the 5532 with dual OPA627. Both are a little bass shy-the OPA627 provides reduced sibilance, otherwise both are very detailed and smooth.
Yesterday a pre-assembled board with AK4396 arrived(these things are so inexpensive) and the most significant improvement is an almost absence of sibilance, in stock form. I haven't tried swapping the output chip yet.
All versions are a little lean on bass but highly listenable.
Now waiting for some Wimas to try(not sure what improvement to expect).

Peter

For OPA827 eBay seller Audiosector, for Browndogs directly from Cimarron Technlogy.

Start replacing the regulators with ON Semiconductor parts, as per my BOM.
