Fully Digital amplifiers

I am using 4 of these plugged into a Raspberry PI 2B (running 4 instances of SqueezeLite) to play music (through a multi-channel amp) to 3 different rooms and a pair of wireless speakers. All are individually controllable through the Logitech Media Server interface. This is a high quality yet inexpensive solution for "whole house" audio. I have used these since 2015 and plan to buy more when I add more rooms to my "whole house" audio system. Highly recommended.

Hifime UDA38Pro DAC (ES9038Pro + SA9227)
I always felt skeptical about investing in DAC, but man this little device proved me wrong, what a difference, it's a day and night difference compared to my focusrite. Worth every penny.

FINALLY something that works with my Steinberg UR824. USB noise is gone, sound is clean.

Coming from Resonessance Labs Concero HP with the Sabre chip ES9018-2M, and also using the internal DAC of the Woo Audio WA7 2nd gen for awhile, uda38pro is definitely an upgrade coming from both. uda38pro's sound is more clear, natural, and musical. There is also more space between instruments and the details stand out more. This is what I am using to feed the WA7 and the combo sounds fantastic with HD800S. Like others said, use an external power. The signature does not change but the sound definitely get slightly enhanced and opens up a bit more. I am using a DC 12V 2A that I had sitting around. For $250 and after using it for a few months now, this is a no-brainer recommendation.

Hifime High-Speed USB Isolator
This is by far the least expensive 480Mbps isolator you can buy anywhere, so I picked up two of them. Internal build quality is satisfactory - the SMD components are hand soldered. If you will be toting it around then be sure to glue the cable strain relief to prevent rotation!

I'm currently using this isolator on a Roland VT-3 (vocal processor) that previously had terrible usb noise in the output signal. After plugging it into this device, the audio is completely clean! If you are having problems with USB midi instruments and noise, then this is the device for you! This was running on a raspberry pi (linux) and through a powered usb hub. I'm probably gonna get another one so that i can run more of my gear on usb instead of midi din.

I like Tripath amps very much, and this one is a great sounding one. It runs a little hot at the rated voltage, so I have added a very slow and silent fan to solve the heat excess problem. Very nice amp, really.
Hifime High-Speed USB Isolator
I acquired a Roland TR-09 earlier this year and was disappointed when I realized that I couldn't rely on recording from the unit, due to a whiny/buzzing sound coming from the main output. A USB Isolator is what was needed. The problem now was the TR-09 needing min. of 400mA to power up. All USB isolators on the market were only capable of providing 2-300mA of power, which wasn't enough. I then came across Hifime and their USB High Speed Isolator. Nick was very good and patient in replying to all my emails with questions on the unit and kept me up to date on the status of its release, since I had pre-ordered one. The unit arrived yesterday and IT WORKS! The whining buzz of the outputs of my TR-09 are gone and it hasn't affected operation of the unit either. It powers up and responds to midi CC messages over the USB, as if the isolator wasn't even there. If you have a bus powered audio device that is causing you grief due to ground loops, then this is the device for you.

Hifime UDA38Pro DAC (ES9038Pro + SA9227)
I own the ES9018 which I really like. Compared to the ES9018 the sound of the UDA38Pro DAC is so much clearer and a new dimension opens. Best choice for the money.
Hifime UDA38Pro DAC (ES9038Pro + SA9227)
Very nice sound ! I used output supply of DC 12V 2A. From low to high sound area I could hear in reluctance. This UDA38PRO is very calm

Hifime UDA38Pro DAC (ES9038Pro + SA9227)
This DAC is amazing, clear, transparent, natural, warm with details, with body and incredible 3D sound. The music literally jump in your face. A real eargasm. My system: Raspberry with Moode, usb cable with external low noise 5V, UDA38pro, Yamaha A-S500, Boston acustic A25. I use external 12 V power supply. Realy reccomended!!!
Hifime UDA38Pro DAC (ES9038Pro + SA9227)
Received it today via GLS. I'm absolutely in love with it ! Plugged it into my laptop which has Windows 10, switched the input to USB and it worked out of the box, just as advertised. Maximum format supported by the control panel is 32-bit, 384khz. I tried it also on another PC with Windows 7. Here I had to install the driver which can be found in the Support menu to get the full format support. In comparison to my older DAC which has a dual AK4490 balanced output, this ES9038Pro feels superior and the difference is noticed already on first use. However, one missing feature for my taste is a Bass Boost functionality for which I use a Software Equalizer. For anyone using a PC, I would recommend APO Equalizer and Peace GUI. The AMP is powerful and extremely loud, so careful with the volumes :) The volume knob is smooth and nice to operate. The device only gets mildly warm and not hot at all, so this is great as well. Note: I use this DAC with my Sony MDR-Z1R headphones.
