Sold
Have two sets of Miro PCM1704 DAC boards for sale.
I will only get either board sold, and I will keep the one not sold.
Please read the condition of the board stated below, and note the individual price.
What you need to provide :
1. You will need to give it PSU with rails +/-5V (Analog) and +/-5V (Digital).
2. i2s source (Amanero Combo384 USB-i2s, JLSounds i2soverUSB are some examples) is needed to feed it in order to play music.
3. Two pieces of single op amps or whatever IV stages you have.
4. Chassis, wires, connectors etc
Board fully populated with good quality caps eg. Elna Tonerex, Nichicon KZ, Vishay mkp and Kemet mkp film caps, Panasonic acrylic caps, Samsung ceramic caps. all the signal resistors are low noise non-magnetic resistors with copper leads, good quality Nextron IC gold plated contacts sockets. Packed with high quality components. As seen in the pictures, both boards have different types/brands of components. Both boards also have u.fl connectors installed in case you would use them.
Payment by PAYPAL FF please.
I have sent 50+ packages to US, EU and a couple to Asia. All receive the packages in good condition.

Board A
PCM1704 chips with one white dot - known to be J graded by BB at some point of time.
Important thing to note is these chips are recycled chips from a very reliable seller, with proper equipment and controlled heat to remove the chips.
I have run the board for the past 3 days without power down and playing music, and it is working without any issues at all. Rock steady.
Board + shipping registered & tracking = 185 USD

Board B
PCM1704 K graded. These are bought as NOS, is truly brand new chips, not soldered or removed from any boards.
If you need to know who I bought these from, I will tell you if you purchase the board. They are from a very reliable member here whom many have bought rare chips from. That person has requested not to be mentioned here openly because he has stopped selling his items and too busy with real life issues to handle requests here.
Board + shipping registered & tracking = 270 USD

Wow, very tempted with kit A. Rare as rocking horse teeth.
What is your impression of the sound with these Tan, up there with AD1862? You are an expert on the NOS chips now 😉

Hello Rich @passive420
I am not the NOS Chips expert, Miro is the expert....😆
Silky smooth.... totally no graininess to worry about despite testing with some lowly op amps.
I would say it is easier to make it sound good than the PCM63, which requires some care in choice of IV options or some passive parts.
Less bass than the AD1862, but i the PCM1704 has more resolution and details without the brash.
I know some mentioned that the PCM1704 is not as good as PCM63 or even the AD1862.
But in my system, it has the finesse, delicacy and resolution of a fine player.
Well, opinions are just opinions.
@Will2226 sorry pal I took it.
I have too many DACs but really wanted to try the PCM1704. Should I want to sell this one on, you will be the first to know 😉 Ultimately if I can source a pair of PCM1704 chips I'd like to build one with JLsounds USB on board.
In the meantime I have PCM58 and AD1865 here if you fancy them.

The Resolution Audio Opus 21 that I have and use has the PCM1704s in it (4). I really like it and haven't looked for a new player/DAC since buying it used a couple of years ago.
UPDATE : Another Board is Now Available
A fresh new board has been completed and tested.
No op amp will be provided since i believe most of you would have your own stash of op amps, so as to avoid unnecessary costs.
Two single op amp is required for the IV portion of the board.
Board + shipping registered with tracking = 180 USD.

Hi @EUVL,
Slipped my mind to mention like i did for the above J graded chips which was already sold. This new board are mounted with recycled chips.
I have just added a note to the listing for this board.
Not from Chinese sources. Carefully removed with heat control.
The board with the K chips (Board B) are brand new unused.
