Negative. There are no bypassing caps on the piggyback board. That's a problem, I have talked about, here is a confirmation. I had PMD100 digital filter in my early 2000 CD player. Better than a typical chip filter these days, but it can't compete with modern FPGA implementations. Trust me on this.

So you did test R1 on USB against Adcom on optical? Why not both on optical? Other than that, you should feed R1 with 8x oversampled source, knowing that Adcom is oversampling. You may be not NOS guy after all... :) Your Adcom beats my fatigue record with Topping D30 by 5 minutes! Since then I...

This is isolator plus 2.0 hub as discussed before. Initially I was going go for it, but it is not disclosed what isolator chip is inside. Now there are more offers and this offer for $71 is safe and priced well. Alternatively ADuM3165 dongle ~$42 (many offers) now overpriced comparing to...

I don't really fall in the audiophile 'reclocking' pitfall. It is important after conversion to the synchronous datastream (S/PDIF types, less for I2S) or on a long run cable when occasional drops are experienced. If there is a hub chip that reclocks USB frames as seen on the photo, I see no...

@droid23. Glad, you found a problem, you are proactive user. :) That's correct. Topping XMOS based DACs are UAC 2.0 compatible and Windows will use built-in drivers. Unless you want to play Native DSD using ASIO output (which is not easy to setup in Foobar) you can stay with Windows drivers...

@droid23. Check out, there is Youtube Source component for Foobar. :)

To add to the previous response, since the version 1.6, Foobar dropped default interface called Direct Sound and switched to WASAPI. Now WASAPI is a default Foobar interface, if doesn't say 'exclusive', it is shared. Shared goes through system mixer and output sample rate is controlled in the...

It will fail, a long route for DI-24HE. :)

Did you?

Nothing wrong with this. Quality components, like caps and soft recovery diodes. Two stage regulation, transformer with two separate windings gives power to both USB host and output side. A final opinion depends on the price, expecting $80-$100. :) I would only put AC power switch close to the...

Equivalent of Ifi Defender, but cheaper. :)

Not isolator. LHY has isolator in their offering, at least twice expensive, here you get a good power supply, important for the receivers that use USB power. It is a class of 'purifiers' that include common mode filters on the power line. It has 'isolated' ground, but it is probably just ground...

Yip, saw this one today. Very basic, that one "no stock" would compete with $80 model. You can get one, then later connect in series more advanced part with external PSU connector. .

I guess, it doesn't need burning. Enjoy. :)

Sorry, this is old chip (low and full speed only), not sure will be UAC 2.0 compatible. Only for old DAC's, maximum 96kHz. All new ADuM high-speed (480Mbps) isolator chips are ending with '5' or '6'.

Well recorded CD's sound great on R2R DAC, you don't need to tell me that. :) .... I also have problem with 24-bit recordings, they are over-smoothed, monitored on Delta-Sigma DAC's and... this is critical.... what you are receiving from streaming services is heavily watermarked. Hi-res...

I am positive, burning will fix muddy bass. It is not the attribute of the Audio GD sound. The other thing is also related to burning. As you enjoy every note on some tracks, I am sure for a final effect. These track you do like have a simple sound, right? I mean solo or duo with no much...

OK, I stand corrected. Regarding matching impedance, a message is clear on this issue. At least for me it looks correct.

I think the main purpose of the DI-24HE clock output is for feeding upstream equipment like streamers. Is your data connection I2S? Synchronising both devices on S/PDIF makes sense, but for I2S not sure. @FredA made experiments with DI-20HE and found that it sounds better when attaching OCK-2...

@naynay keep quiet. :)

I guess, optional. Some PSU's come with two-prong mains plug, phone chargers by example.

Soldering fuse solves poor quality contact problem. It won't get any better without fuse.

I assume you have already cycled power of DI-24HE. If not, do it now. 1. Unplug DI-24HE USB cable. 2. On Windows go to the Control Panel (not a Device Manager) and uninstall the existing Amanero driver. 3. Run setupuac2.exe file and follow prompts. There are two parts: for a Windows interface...

You are always naynay. :) A product is selling for one month or two and has no negative feedback.
