niamex: I bought a pair of those from ebay yesterday. I'll see if they are better then the stock ones.

Please note that you need a matched pair what means that both channels /left and right/ will sound same - you got it ?

I guess they are not matched. I see I hurried up with that purchase. It must be difficult to find a matched pair unless they are taken out from working CD-player.

That's right. I will look around and imform in case I find some pair. There is a chance yours to be quite similar and by all means much better than the L grade but only in case they are really Japanese which I hardly believe. Please note that Burr Brown  /now Texas instruments/ ceased the PCM56P production in Japan long time ago so the crooks are simply cleaning off the sign and printing another /Japan/ on the chips.

Is there any chance they are selling originals?

I do not know, may be someone else will give us some info but I haven't seen a matched pairs,  which is the most important goal and frankly speaking I wouldn't pay attention to that offer. For  about 100 EUR you can get a top player which may need some cleaning and some power line or whatever upgrade and you will have a good transport for your CD collection and a pair of original PCM56P-K chips. It is your decision anyway.
Cheers,

Digi-Key has them (no indication if they're made in Japan or not) but the minimum quantity is 50 for ordering.

this is a nice dac.

 

[robeeert1]

I've  received the DACs today. The difference is fundamental at least in classics.
It's very hard to describe the sonic differences between the DACS because everything changed. It's not the same like changing cables or tubes,
you can easily hear that different DACs (parts of the Havana) are creating the sound.
The timbre and resolution are better.
Especially on transparent system and my electrostatic headphones.
The super change for super change money. Thanks Niamex. WOW !

I do not really think these are fake, quality of writings are better than on original Korea DACs.
I have to purchase another pair of these for spare.

These are actually shipped from Singapure not from Hong Kong.

I am happy you are pleased with the replacement. Let's see what is happening after I send you the matched couple from the KENWOOD. Otherwise the coupe you got seems OK to me.

Sorry Robert, I have just payed attention - your DAC/s are J grade and I will send you a K grade which is the top grade. So do not order J grade please.
Cheers

What is the difference between K and L grade? Is it so big as between L and J grade?
