To be honest, I do the same. I experimented with the 'valve' and the 'transistor' options and couldn't understand how these really were high fidelity options.
For the “valve curious” crowd! :D

I couldn't discern any difference between the 3 so left it neutral.

Sorry to hear that, as it were :). There are very audible differences (particularly on the 'Valve Sound' option) on my set-up. These are especially obvious regarding bass reproduction, dynamics and imaging. I expected that to be a universal outcome, which underpins my curiosity regarding their functionality.

Can I ask what set-up (gear) your D90SE runs with?

Trust me, everyone who has commented on these modes on various sites have agreed-no one can reliably tell a difference. My rig is in my sig. Eversolo DMP A6>D90SE>Freya+ passthru>Buckeye 3 ch Purifi>F208's.

Many commentators then, and a nice system. Strange feeling to apparently be the only one who can hear the notable (noted) distinctions! :)

But more seriously, I am amazed that even the Valve Sound option is not obviously distinct (although I could understand greater difficulty in distinguishing the distinctions between the OFF and Transistor Sound options). As I said, it is not a small distinction for me.

If one wants to see how these modes look like here they are:

We're talking 60db and 40db SINAD for Transistor and Tube.
(that could put some SINAD chasers to rest and it's ironic to happen by a SINAD champion)

If anyone wants a Topping D90SE please let me know. It's barely used and needs a new home.

I ask for the help of experts!

How to use the Topping D90SE and Topping LA90 kit with the greatest efficiency?

1. The D90SE DAC should be used in DAC mode, WITHOUT volume control, - and the LA90 amplifier should be used in volume control mode.
2. The D90SE DAC is used as a volume control - and the LA90 amplifier is switched to the mode WITHOUT volume control.

USB cable comes to the input of the DAC, and 4-ohm speakers with a sensitivity of 88.5 dB (Vela 408) are connected to the output of the amplifier. The interblock cables are XLR.


Thank you very much!

The safer way to do it apart from SQ,etc is setting the amp to the loudest you will ever need and then control level by the DAC.
That way even if something that will present the full DAC level occur there will be some kind of fail-safe.

Thank you! I was suggested to use the amp in through mode (without the volume control) and the DAC as the digital volume control.
Luckily for me, my low-power amplifier (Topping LA90) creates unbearably loud sound even with the volume control in the middle position, and on the other hand, my speakers have a 3-5-fold power reserve compared to the maximum power of the amplifier - so there can be no breakdowns in this equipment.

The danger with a low power amp is always when reaching the clipping point.
Every rating after has little meaning.
So better be on the safe side,after all the result will be the same and even better (depending the quality of the amp's VC,lowering it will allow you to have better SNR on the DACs side,not that any of this will be audible at that level though) .

Thank you! I probably didn't explain my situation correctly. My low-power TOPPING LA90 screams unbearably loudly even with the VC in the middle position. I probably don't understand what clipping is and what you told me about it.

I probably didn't understand the second part of your advice either, but just in case, I'm publishing my gratitude to two kind people, which contains links to their explanations of the topic that, as I assume, you explain in the second part of your advice - for which I am very grateful to you!!!

Have a look at the chart of your amp here and follow the lines:

1717663214133.png

The sudden rise you see at about 50W is when the amp passes it's point of linear operation.The lines show you that distortion and noise skyrockets at this point (the lower-the better) .
Of course you will hear it if it happens and at that point you have to reduce level as clipping has a lot of unwanted side effects,can destroy speakers,etc.

I've heard good things about the Vela 408's. How do those compare to a B&W 804 D3/D4?

I think that statement hits the nail on the head, find decent specs and the rest is up to you.
