Yes. ibasso posted in the past that this is the USB they are using so there is less strain on the connection. They had it designed this way, from what I remember.

You can always use an older Tidal, which often works better anyway.

The LTA amps are easy on tubes. The Velo would be easy on tubes and unless the tube is wonky to begin with, it should last a very long time. It is better to have a tube on if you are going to use it over a 12 hour period than off and on, which is harder on a tube and will shorten its life.

The 12SN7 is a quieter tube due to the heater being 12.6 volts so you are further from ground. I used to always raise the ground to around 50 volts. A tube then is very quiet. The tube sees the correct heater voltage but a resistor to ground makes it electrically appear much higher.

They get about 80% play time out of all my headphones. The issue?? They DON"T cost enough. People often buy price and go from there.

I heard the amp years ago, pre production but told Fang that the amp needed to be improved and needed more volume. There were about 8 all running to make sure the headphones and amps did well. The headphones are very good and a very good buy. The amp is still the same amp, sadly. But at least...

I think you have to go through ibasso.

How did you like the Inspire? I don't know if Dennis is still around. I used to do work for Cary Audio years ago when he owned it.

I have a Supra but haven't done 160. Would be fun but the ticket wouldn't be. It will do 165 but isn't good for much faster as the body is built for 160 to 165. Yep, got to protect the ears.

And eventually you will hear less. Listening above certain levels for a length of time will ruin your hearing. You will live with tinnitus and frequency loss. It is like skin cancer, your skin doesn't forget and neither will your ears. Safeguard them or later, you will wish you had.

You have to use a line in, from a line out. I would look at the manual for where the in is and what type of connection it takes.

Yes but they won't sound optimum. I follow the curves for a tube and go from there. While the 12AT7, 5751, 12AU7 and 12AX7 will work in the same circuit, it doesn't mean they will sound there best. Will anything go bad, very doubtful and you will have sound and maybe something you like. But as...

While the gain of the 12AT7 is very close, 60 vs 70 to the 5751, the electrical properties are very different. This shows up when you test the tubes, as the settings are very different between them. I built up an amp years ago and wanted the ability to use 6SL7 or 6SN7. Like going from a 12AX7...

If you don't know, it is not a stupid question. It is more stupid to act without knowing and not asking. The coax output is a digital output to another dac system. The DX320 would act as a storage unit for the music to an external dac via the coax cable. The line out is using the DX320 dac...

Even though the 12 AX7 is rated at 100 and the 5751 is rated at 70 you don’t notice much difference between the two and I think that the 5751 would be too much gain and would possibly cause distortion. Also, those two tubes are more of voltage tubes whereas a 12 AU seven and the other Tubes are...

To me, it is a very good value and ranks up there with much more expensive daps. You have the layering of sound, transparency and very good bass. It uses the ROHM desktop chip so the rest is up to you and what your personal preference is.

At nearly 100 hours of burn in, the Velo has gone through phases, like any amp, in my experience, with burn in. What I am getting now is a wonderful feeling of being at the performance. By this I mean the sound doesn't just hit you up front, to your side and front, but sweeps by you as if it is...

I have found cryo to help a little with some tubes and a few, it actually made them worse. But the change, IMO, is minimal.

I have a GZ34 metal base with a huge number of hours on it. I got it used for around 30 dollars because the guide pin was broken. Tests like new and is excellent sounding even after many, many hours of use.

Right?! What better place to have fingers covered in a hot sticky sauce. Ah, music and BBQ!

You could have a barbecue on the balcony!

It doesn't double the power, each one of those is one triode, so you have to use the adapter to make one dual triode. The separation of the sections like this and using top caps, is very special and superb for good sound. These are a 7193 Ken-Rad. There are 7193, E 1148 Hytron, CV6, DET20 and...

Ok, a change in tubes to the 7062 PQ with Hytron, which are Sylvania 1952 clear spacer (bad boy) in 12SN7. Tubes are so very easy to change. Wow more body to the sound, a slightly more warmth, which is natural, adding to a full sound with excellent dynamics and depth trailing off into the...

I have put in some 7062 PQ box plate tubes in the driver section. I tried them before but at that time, they sounded a little bright and slightly thin on the Velo, but with more burn in of the Velo, they sound very good now. Excellent depth and what is remarkable about the Velo, is it ability to...

Here is a nice internal shot of the Aero DAC. Very nice layout! You have the Zotl amp section on the left and you can use 12SN7 or 6SN7 tubes.
