If they manage to control the smell I’m all for it!Oh I've already emailed them asking for a baby camel hair version... will be the smoothest sound ever. I'm told they're looking into it...![]()
Not really though when you consider the only main difference is ESS vs AKM and the word velvet.

Sorry, but when it comes to a blind test between two transparent DACs, that's just not enough."To evaluate DAC performance, I paired the E70V directly with my time-tested studio monitors via XLR. I switched between both of the units, volume-matched, and used the same AQ cables. Although the difference is quite small, I was able to distinguish between the E70V and E70 8 out of 10 times in a blind test…"
I hope you're not trying to connect two DACs to one USB port on the Raspi using a simple splitter cable, because that won't work.USB A male to USB A female splitter cable
The USB cables don't carry an analog signal that you could measure the voltage of. You need to measure the voltage at the DAC outputs, in-situ. Or at the Amp output works as well. Use a 60Hz test tone for this, and make sure any replay gain is turned off in the player.This is where I need help. I have a multimeter, a Radio Shack handheld sound level meter, and pink and white noise FLAC files. I was planning to check voltages on the USB cables and sound levels through my speakers. What is the best recommendation for level matching?
Give your son a phone with a random number generator running on it that outputs either a 1 or a 0. After each trial when you're done A/B-ing and tell your son which DAC you think is which, he should refresh the generator. If it's a 0, have him plug out both DACs and plug them in the same way as before. If it's a 1, have him plug out the DACs, then plug them back in the other way.Blind:
I will have my son connect the DAC USB cables and XLR cables between the DACs and HPA-4. The DACs will not be visible to me, and I will switch between the two HPA-4 inputs. Switching should be nearly instantaneous. I will have control of the HPA-4 remote and will switch between the two inputs at will. Only after I have completed the comparison will I look to see which DAC is connected to which input. How many trials should I run?

You can certainly connect two USB devices to one port on your Pi using a USB Hub. Those have a controller inside that assures proper communication. As a result, both DACs will be detected by the Pi as separate devices.That was the plan to avoid having to switch inputs/ouputs on multiple devices. Why would it not work? The Pi has 2 USB 3 and 2 USB 2 ports. I guess I can use one pair of outputs. Are they both active or will I have to switch between them? Looks like I'm going to have to do some experimenting.

What doesn't work is connecting two accessories to one port with a simple USB splitter made of only copper wires.
It should be possible to tell the Pi to output the audio to two USB DACs simultaneously, but I don't know if or how this works using picoreplayer.
Let me understand, when you guys changed from es to ex that was something else?Prof. Wolf posted measurements of this unit 8 days ago;
It seems this implementation of the AKM 4499EX is also showing the IMD hump which showed up in the measurements of the SMSL D400EX.![]()

台式设备 随着"三小强"中SMSL和Gustard都推出了自己的4499EX解码器,拓品的研发总让我感觉是不是有点滞后?不过随着我拿到这台 Topping E70 VELVET 我打消了疑虑,拓品还是他家的老样子……www.l7audiolab.com
From what I can see it's basically the E70 with an AKM chip instead of ESS;

Greetings! TOPPING E70 VELVET DAC!
The twins of E70 with higher capabilities! TOPPING has announced numerous superior DACs, including the D series, and E series, all of which play very well and get many high-praised! And this time, TOPPING updates its E series and invites E70 VELVET to be a new member! From what it is named...shenzhenaudio.com

Do you mean the SMSL D400EX & SMSL D400ES?changed from es to ex
There is so many factors to take in consideration when it comes to music that I don't know where to start.Most of the reviewers say „take the velvet“. What would you do? Will there be no Test Here? Difficult decision. I think dacs are a Bit too expensive in comparison to amps.
Do you Know if hifigo does often offer them cheaper or not? I can‘t Decide until tomorrow.
