Today I tried my new Burson V5i-D and OPA1656 along with stock OPA1612. It is quite hard to tell differencies in SQ beetween these 3 opamp from first impressions.

I think each of them needs proper burn-in about 150hours or so to reveal each opamp more noticeable individual signature. I swapped each of them 4-5 times and had noticed only minor differencies affecting sound qualities.

V5i-D out of the box sounded the most sweet in vocals, almost without any harshness or sibilance in high frequencies, it sounded also the most tammed out of three that I have tested. Rhytmic and easy going sound. I have read somewhere that the sound of V5i-D changes quite noticeable after burn in about 150hours, so will see...

OPA1656 is an upgrade for some people in my opinion to OPA1612. It sounded a little more coloured, more textured, more space dimensional with better instrument separation and a little more detailed in nuances compared to stock OPA1612. Vocals sounded a little more recessed in the bacground and instruments had also more small nuances and were presented more forward in the overall scene. But these nuances were very subtle.

OPA1656 and OPA1612 also shared a little more harshness and sibilance compared to V5i-D. So for the first impressions it is very hard to tell differencies... I think everything will change more obviously over the time...

that pro is a tank!!! I like it!

This is a comparison photo of XDUoo XD05Pro, FiiO Q7 and EarMen Angel sizes.

XD05Pro is too big... but the sound is the best among these three.

This is serious and surprising information, because the angel, next to the diablo, is considered one of the best dac/amps in its class and in this price range.

The advantages of XD05Pro in my personal opinion
1. Very wide soundstage
2. Top-notch resolution
3. Holographic sound
4. Select the OPAMP or DAC Chip that suits your taste.
5. Extremely versatile

It can be said to be the best portable DAC/AMP in many ways.

Even if the XD05Pro is connected to a high-current linear power supply of 12V 8A (120W Transformer), Desktop Mode works well.

(XDUoo's recommended linear power supply specification is 12V 3A.)

I have been looking into the various options on where to purchase the XDuoo XD05 Pro in the USA. I am leaning toward Amazon because of their easy return policy in the event I get unit that is not functioning. Others require I pay for shipping back and wait for them to inspected before issuing a credit. Any suggestions?

The orange color of the diode led indicates a fully charged batter

Have you observed any noticeable changes with linear power supply vs battery or vs smps?

Unfortunately the situation is this:

it's been days now that I haven't wanted to listen to any other DAC since I started with this 05-PRO, SPARKOS or not.

I ordered from Amazon and used an Amex card to get their extension of warranty. If there is a problem, Amex is good about taking the side of the customer. I was considering Apos, but they don't respond to e-mail and their on-line chat feature is worthless. I already have the Burson V5-1 Dual which I will try out when the unit arrives. Thanks to the other posters here for helping me decide.

XDUOO has been great helping me diagnosing much USB noise. Asked me to pull the DAC card and reinstall. Will update with results soon.

I did a short test with Burson V6 Classis and Vivid in bal1 (not bal2). It didn't make much of an impression on me. I don't think it's worth it. Classic resembled v5i but sounded too warm and vivid was similar to muses02. This can be checked without modifying the case. More about bal1 and bal2 in my post: https://www.head-fi.org/threads/xduoo-xd05-bal2-vs-bal1.968780/

Hiii, since you have the bal2, if you could, please let me know if the XD05 Pro is worth the upgrade with in stock format and Opamp testing. Thank you

yes, please.
Troubleshooting information are always useful.

Could this be an upgrade from my desktop amplifier? I simply wonder if this baby could hold up to really expensive amps.

It obviously depends what you have as a desktop amp, and what you mean by "really expensive amps". I like the XD05 Pro a lot and have spent a fair amount of time testing over the last few weeks. If space is at a premium and you want to simplify your desktop setup, it could be a great option. As a direct replacement for a good quality desktop amp? I don't think you'd gain much, if anything.

Although far less portable than even the XD05 Pro, I prefer the Quloos QA390LE as a "transportable" DAC/amp. It's in a different price bracket, of course, so I'm just basing this view on sound quality and features.
