Mhdt Labs Orchid TDA1541A Non-OS USB Tube DAC - 192/24

Description

Mhdt Labs Orchid
Orchid DAC is a non over-sampling, no digital filter, structured DAC.
This tends to produce most realistic and natural sound.
Mhdt Labs' Orchid  is rare TDA1541 based DACs around the world that can accept and play 176.4kHz and 192kHz digital signals without bunch of glue logic ICs.
Delivery time may delay due to COVID
Please check shipping fee in your country, there are some area not in post service and hence the shipping will be by DHL and fee is high
Orchid
DAC is capable of up to 24bits/192kHz digital signal inputs yet remains driving legendary TDA1541A R-2R digital to analog output.
The USB input section is in asynchronous operation.
Total four independent  digital inputs; BNC, USB, RCA and Toslink.
The 4 digital inputs are independent to each other, only one among them will be active and is controlled by the tact switches located in front panel.
Stockholm DAC
Tube buffered output, tube in stalled is 5670 tube.

All our DACs installed C-Media CM6631A chip as USB receiver.
For Windows users:  (Mac and Linux not influenced)
Microsoft hasn't recognized usb 2.0' audio as standard Windows topology until very late version of W10.
So,
Before mid-2020, our DACs' USB section configured as PID=0319 (use customized driver, 1.03 is recommended)
In mid-2020, we start to configure our DACs to be PID=0004 (use W10 in box standard driver)
In PID=0004 condition, to use W10 in box standard driver you need to plug in our DAC and let W10 to "search driver from the Web" and then the W10 in box standard driver (digital signed by Microsoft) will be installed by Microsoft.  If not automatic execute, you have to go control panel to install this in box driver.  Why we start to configure our DAC to be PID=0004 is because that this in box driver can be automatically updated if necessary in every W10' update.
PID=0319 and PID=0004 can be changeable by the firmware tool FWUdate.exe (2.0.1.11):
to erase the current firmware and exit.
unplug DAC and re-plug in and execute FWUpdate.exe and choose one of the digital unsigned hex to install.
What PID now can be checked by FWUpdate.exe too
