Sure Electronics AA-AB32313 2x400

[denbret]

Hi, on my PCB I bypass the SMD coupling condos by Obbligato Copper 2 uf, the sound is much more transparent and dynamic. the bass is more precise and the soundstage.

Hello everyone, I could not find AB32313 or AB32512 in the MKII version, which has larger inductors.
Does it have much difference in the sonority between versions?
Thank you!

In Germany though.

Do I have this pinout correct for the ab32313, Vin1 to Vout1 and Vin2 to Vout2, and switch 1 set to off?

What value capacitors for the inputs?

And what value/spec capacitors for the power supply caps along the sides, or stay with the oem values?

There were some tests in the German forum with some capacitors, to choose which one would look better in the input.

I ordered 2 x TAMP2400 MkII which arrived today.
Unfortunately no screw terminals for the supply voltage on the board although on the picture of the shop it had those.
:/

So I had the chance to listen to them.
Given the price point it is just ridiculous even when not burned in.

Imho no need for more amp than this one at least for me.

Crystal clear, accurate and nice control over the woofers.
Plenty of power.
Change the input cap and it will be even better.

Only downside is the fan it is not exactly quiet and I think I heard some slight noise on the speaker output when it was running at high volume.

I used 2 Mean Well LRS-350-36. Also very good value.

Bottom line: Very impressed especially considered the price point.

I am happy every time I see more people impressed with the Gremlin.

This week I'm going to buy mine.

Yes!
The sooner the better
It went past everything I got/heard by a wide margin easily.
Even on subs.
I hope they will be in production for a long time.

Another thing.
If I invert one input of the Amp can it be bridged?
I use + output of one channel and - of the other?

 

[clawmd]

I had not realized that I could use the Meanwell HLG-150H-36. This would allow for a much smaller enclosure since only the amp is enclosed. Are there any downsides to this approach. It seems that it would also move the power supply away from the amp as well.

A 150 watt power supply might be a little weak when intending to drive both channels hard I think.
But it's tiny.

In shorts, NO. The amplifier is already bridged. If you want more power used another amplifier like the Sure 1x800 or something like that. Just check that it is a Thripath board, it is the best sounding of the Sure board.

Ok.
What about the Sure IRS2092?
Good for bass duty?
Comparable or much worse?

The IRS2092 is better in the bass, but only in that range. If you want to use the amp for a subwoofer or bass in an active 3+ way setup, go for the IRS2092. If you want anything midrange-highs or fullrange, the Gremlin is much better.

Ok.
Thank you.

I'm only intersted of sound quality
Thank you very much!

 

[globalplayer]

Price.

No, seriously.
STA510A output stage on the "tiny" one.
STA516BE on the AB32313.
Maybe minor other differences aswell.

I would go for the "bigger" one. Headroom is always good.
I am listening right now to it and it sounds very good.
The other one I don`t know.

 

[DIP8]

Thank you global player
Do you think that difference is clear between these new chips and my ta2024?

sorry for my english..

 

[globalplayer]

Your english is good, no worries.
I never used the ta2024 so I have no idea.
But this AB32313 is the best I ever heard.
I think you will not be dissappointed.
But order the MkII version from hobbyhifiladen.
It has upgraded output coils.
