Bruh, this isnt cheap by no means. You can get a better system thats all in one for close to that price.

Huh? Youre kidding right? You can get better system or similar, thats all in one, for the same price , if not less. People saying its too expensive are correct. You could Schitt on it and come out for less. Topping could of did an all in one, because most people arent going to buy these units separately for what you're getting compared to the competition ---or its own 'down the food chain' amps and dac pairs.

Why have you copied my quote twice in the same post? Less is more Brah...

With respect to your general point, you have no clue what performance is offered by this pair of components yet. Perhaps wait for that before drawing conclusions about what may or may not present a more compelling price/performance offer.

This stack has dropped, welcome to check here, A30PRO and D30PRO, see what you confused.

My initial thoughts were a Dx7 Pro with extra steps.

However looking at the spec sheets, it seems they are Ina different class. 6 watts for power, and quad DACs? I don't know enough about how DACs work to understand what benefits that could have

Of course we won't know until reviews are out, but my immediate thoughts looking at the spec sheet (yes I know spec sheets may not mean a lot) makes me think pricing is spot on

Welcome to check the spec you needed.

Well, I am not interested in specs. I own D30 which had a top spec figure, but it sounds like a s..t.

I am more interested to know whether the amp has sufficient input protection against ESD and DC on the output. There are many cases of a failure and in some cases expensive headphones are blown by Topping L30/A90 and the first version of DX3 Pro. It is important to know what has been done to prevent it happen from future. Details here.

A30PRO has the ESD and DC protection, be rest.

Not challenging you, but genuinely curious... Are you on this thread out of interest in these products, concerned about specific aspects that you believe could be cleared up here, or to take out your frustration over your disappointment with other Topping products?

 

[sajunky]

Not challenging you, but genuinely curious...

Not a challenging request to post photos and point out where protection devices are located on the PC board. After all these incidents with L30/A90 failing for a reason there is no ESD protection, people are concerned.

Now that you have indicated what you are looking for, I would observe that yours is a very unusual request. Rarely have I seen a consumer electronics company respond to a customer’s demand for what is in effect a design review. But, you are perfectly within your rights to ask!

What is unusual in a safety inspection request?

Well, can you point out where a consumer asks for and receives that...? If you were a government inspector in a country where Topping is seeking certification that would be a different matter, of course... But, you are perfectly within your rights to ask, I just would not count on receiving a response

What would be the benefits of the Topping A30Pro and D30Pro stack over the similarly priced SMSL SU-9 and SH-9 stack? From what I have read, the SMSL DAC has the benefit of MQA (if you are into that) and Bluetooth, and the SMSL amp has much higher power. On the other hand it seems Topping amp is better for IEMs, and dac also is a pre-amp. Any other differences?

Great choices for consumers!

I am in the same boat and was thinking that the D/A30 Pro is priced to directly compete with that SMSL stack too.
I opened this thread for that very reason with my pros and cons based on the numbers.

https://www.head-fi.org/threads/whi...tack-or-topping-a30-pro-d30-pro-stack.956511/

Of course, how they sound is what really matters.

I think the SMSL SU-9 could be better based on similar specs, supports more formats and has more features but the extra power of the A30 Pro might be nice. Wonder if that combo would work and how it would sound. The D30 uses the older XMOS USB chip.

From what I see, their numbers are very close. Both have 6W @ 16 Ohms but things seem to differ as the ohms get high. At 32 Ohms, SMSL has 3W vs Topping lists 5.5W. SMSL has 226mW @ 300 Ohms while Topping has 813mW @ 300 Ohms according to ASR.

Also what I do not like is that it was said that the A30 Pro has pass through but it will only pass XLR to XLR and RCA to RCA. If it is really single ended only internally, why is this the limitation? Why can't I pass in XLR and pass through RCA?
