Topping has finally released images of the L30 headphone amp to match their E30 DAC. It uses the same chips as the A90, with a ballpark cost of US$150.

Audio Precision measurements look very promising at ASR. It looks like it's going to set the new objective benchmark for budget-end amplification.

Very excited personally! Thought I'd start a thread to gather some thoughts?

 

[trufunk]

Sweet!! When will this be released?

 

[iamwhoiam]

Apparently in July-ish. This will be Topping's next amp before the A50S.

Prototype measurement

 

[Matoriv]

looking forward to it and if it is as good as the hype, will get it + E30.
else magni heresy + modi 3

There's no reason why this won't be the budget king.

Some objective measurements posted now:

I mean does Heresey not measure just as cleanly? Not sure if it's putting out 2W tho,

Heresy
THD+N - 0.000113%

L30
THD+N - 0.000063%

Obviously both outstanding.

Ahhh ehh ok better that's cool!

I would also vote for L30 (if a price drop to $100). A reason is obvious, I think.

Use of TPA-6120 chip in a nested loopback configuration is inappropriate for the amp @ $500, but completely justified for a $100 product. See my comment: https://www.head-fi.org/threads/topping-a90.927412/post-15746300

Topping released their budget DAC E30 months ago, and headphone amp matched with expected and concerned as well. Now L30 is approaching and on sale tomorrow at US$139.99! What's surprise will bring to us?
At the same time, any problems are welcomed to consult at shenzhenaudio store.

Of course, there is a review before L30 pre-produce from audiosciencereview can be refer: https://www.audiosciencereview.com/...asurement-of-topping-l30-headphone-amp.14252/ , we also will arrange more reviews for your reference.

Here pls refer more details:

ASR "established experts" didn't pickup design fault in Topping A90. Also ASR measurements didn't show ground loops introduced by such a fault. It is despite of the fact that ground loops are typically a plaque of Amir's equipment (only when testing non-Topping products like TotalDAC). I bought Topping D30 (featuring the best measurements on ASR) and it produce trash, not a sound.

From my experience ASR measurements are cannot be trusted. Having said the above, L30 doesn't look bad and is worth trying. It doesn't have dual MeanWell SMPS outputs hoocked in series (so is free of A90 fault) and it doesn't cost $500. .LOL.

I expected a price closer to $100, it is a real value of L30.

The E30 is $129 without wall adapter, so $139 is reasonable for a sister product.

There are plenty of designs and commercial products in service which use SMPS in series. You have already received replies in all the forums to this.

Well, such claim require a proof, please follow.

The L30 has an external VAC adapter, therefore likely to use an internal linear rail (hypothesis).

Neurochrome HPA-1 used 2x SMPS in series. But that is beside the point. This is an L30 thread and nothing to do with the A90, which was predominantly designed to be used balanced.

The L30 performance as unbalanced for $140 looks phenomenal.

Please stop trying to hijack other Topping threads, it's not necessary.
