Topping A30Pro Review (Balanced Headphone Amp)

[ninetylol]

Regarding the rear balanced output (BO) 1/4 jacks do you need TRS or TRRS terminations here?

Answered before too. TRS.

 

[Tortie]

Answered before too. TRS.

So only one ring is necessary. Thank you!

I was wondering what did you really mean by TRS and TRRS. Perhaps you meant TS and TRS. Make sure it's TRS not TS.

I would like to see a teardown with high res photos of the internals. There needs to be more detail on the parts used. What pot are they using? ect

When you buy one tear it down and show us, thanks in advance.

Not bridged just same wiring. The connectors are just for convenience. But the power is still very high. Designed for He6 and DT880 600Ohm.

Can it easy drive an Ultrasone 5 unlimited edition, 32ohm 97db? Thanks

[QUOTE = "JohnYang1997, post: 673513, member: 5166"] Mi chiedevo cosa intendevi veramente per TRS e TRRS. Forse intendevi TS e TRS. Assicurati che sia TRS non TS. [/ QUOTE]

Could it be joined with a Matrix mini-I Pro 3 dac? Thanks

this question been answered. This forum really needs a thread-search utility like Head

Is Matrix a dac+headphone AMP already?

Heck I don't know. This new 1/4 jack implementation is confusing. None of the cable makers I know of even sell balanced 6.35mm cables. There's never been a headphone amp or DAC that's used this method of inputting/outputting BO audio. This is going to confuse the hell out of people.

You can connect the XLR outputs of the Matrix mini-I Pro 3 directly to the XLR inputs of the A30Pro using XLR-XLR cables but also from Matrix (using XLR out using XLR-TRS cables on the A30Pro.
Basically the TRS outputs also function as an input as they are simply connected together.
You can't use both TRS and XLR as inputs at the same time though.

Yes sure but has very high impedance so drives with enormous difficult low impedance and sensible headsets

It's gives the same power 1/4,4.4mm,xlr gives a tad more not much if I'm correct.

They are very common in the pro circuit.
XLR and TRS are both used for balanced operation. Often consoles even have both and there are plenty of cables going from XLR to TRS and vice-versa. You would have to buy these at music centers etc. Not in your typical HiFi shop. For HiFi TRS 6.3mm is reserved for stereo headphones.

You can connect the XLR outputs of the Matrix mini-I Pro 3 directly to the XLR inputs of the L30 using XLR-XLR cables but also from Matrix (using XLR out using XLR-TRS cables on the L30.

You can't use both TRS and XLR as inputs at the same time though.

L30?

I would've not bought Matrix for low impedance phone then.

TRS is 3 contacts though beware. Else it wouldnt be balanced.

 

[Giangi71]

So...I use Matrix only as a dac streamer for Roon! I won't use it as a headphone amp. The Topping A30 Pro will be the amp side, do you understand?

You may consider Matrix Element I which has better output impedance sans balanced headphone output which A30 Pro is lack of either.

I've tried it. Mini-I Pro 3 sounds better as a preamp

 

[solderdude]

L30?

sorry A30.. fixed it

 

[Giangi71]

sorry A30

I think A30 Pro it's the best solution for me xlr in A30, xlr out Matrix and so Roon wifi streaming
