Sorry I noticed you are using integrated amp. I mean if I can directly connect the Dx7s to a poweramp and use the Dx7s as pre-amp (i.e, volume control).

Is there a way to disable line out on the Dx7s ? Thx.

I mean to connect the DX7s to a power amp instead of pre-amp or integrated amp. I know in theory it works but wondering how good it is.

Can someone share his experience using the DX7/DX7s as pre-amp? Thx.

Wonder if dual 4497 (i.e., D70) is a better product? One thing I dont like about these Chinese DAC is they never update the firmware/driver though.

Can the nano iusb3.0 use 12V DC power supply ? Also may I know the size of the PS tip and polarity ? Thx.

Because 1. Saga S takes 1 tube while Valhalla takes 4 and I want to has the most tube sound 2. My next upgrade will be an integrated amp so I dont want a pre-amp The Lyr and the Saga S takes a single 6SN7 not sure how it compares to Valhalla though.

I dont need the headphone amp func. I just use it as tube buffer for my powered speakers.

I am torn between MK3 and Valhalla 2. Seems Valhalla 2 has much less choices in tubes but some says Val 2 is a much better amp. Any opinions? ps. I am currently using the FX audio tube 3 with GE JAN5654W as tube buffer.

How much tube sound I can get from the little bear b5? I am more interested in the tube sound than the amp portion. I have the pioneer 30R & UE900s. If it is on the same level as FX audio tube buffer I would be very happy.

Anyone used the little bear b2 with iem ?

Does this combo works? My tube-03 works fine with the original tube and can only get 1 channel to work (the non-working channel sounds very faith) if I use the GE5654W. Does Tube-03 & GE5654W works? As I know the Tube-03 are cabled in series so if 1 tube is faulty there should be no sound on...

Isnt the white thing the thermal pad?

Think about it. 1. If all filters on the same device sound the same, why would the manufacturer implement 1 single filter only or firmware update? 2. If all DACs sound the same, why there are different manufacturers and/or single manufacturer with multiple DACs. 3. Does it make sense, if...

I trust my ears. I swear I can even hear the different between the latest version v5.3c of the firmware vs older firmware as they changed the filter all together and forced oversampling. The latest firmware sounds un-nature to my ears.

From the device serial no or win driver/device manager.

I have the iOne for over 1 year and the Topping DX7s (big bro of D50 with additional phone amp & etc.) for about a month. The DX7s does sound quite a bit better than the iOne. I expect D50 should sounds better than the iOne imho.

While number does not equate SQ but the testing seems indicated there is a problem with clipping on the device.

Does anyone get auto power off to work? I am currently using RPI3 with a digi card coaxial out to the DX7s and auto power off does not work.

I think he is talking about this LPS. http://www.teradak.com/products/88.html

I assume the sound signature is also very similar.

How does sound quality compares?

How does it compare with iOne sound quality-wise?

What is R2R 15? Not seem this model on the audiogd web.
