E-stat amp with balanced inputs and gain switch for $400? Finally!

 

[BTD1]

probably Birgir will buy one...

He’s a very smart guy with strong opinions. I can’t wait to read his thoughts on this unit.

This is the rear, looking at the 15V barrel connector. There is also package contents showing an adapter:

Thanks. Wall wort.. Probably room for upgrade PSU

Hi all,

Here's another fantastic launch from TOPPING. If you're an electrostatic headphone owner, you know that the right amplifier can make all the difference. Enter the TOPPING EHA5 Electrostatic Headphone Amplifier, designed specifically to help you discover new levels of audio detail and performance. With an impressive 146dB SNR, a powerful 700Vrms and 2000Vp-p output swing, and convenient pass-through functionality, the EHA5 is the perfect companion for your electrostatic headphones, providing a listening experience that's truly immersive and enjoyable.

Here's the link to the blog for more information: https://apos.audio/blogs/news/topping-eha5-amp-announcement

what is the current output of the amp?

what is the current output of the amp?

700v 1100 p to peak i think

 

[Tugbars]

700v 1100 p to peak i think

that's not current. That's voltage. The problem with electrostatic amplifiers is not the lack of peak to peak voltage. The problem is lack of current especially in high frequencies. That's what bigger amplifiers do better

That is very true. My bad

Does anyone have at least an educated guess on how this would do with the X9000?

 

[Reputator]

"Appalling" signal-to-noise ratio

As @Tugbars said.

Anyone have MILLIAMPEREs or WATTS output performance of this thing!?!

On the Stax Thread III, Kevin Gilmore said that this amp is sort of a souped-up Koss amp. 15 watt power supply. With that little power, I highly doubt it can sustain 700 Vrms across the entire frequency spectrum. But, it looks like a nice cheap starter amp, and it should be a win based on price and availability alone, since Stax has discontinued the 252S and the low-power SRM-D10 is over twice the price (though portable and DAC-equipped). I'm quite tempted myself.

Wonder how much an upgraded PSU will make a difference.. They should sell an optional PSUbooster unit

@Apos Audio I think it is too tall to fit on the Topping SR2 rack. Is that correct?

 

[Hal Rockwell]

Here's the product page on ShenzhenAudio.com. Who gives a rat if the SNR is 146db if 3rd harmonics sets in -101db and multitone graph shows that distortion in lower frequencies is -80db?

OMG, this is making me reconsider my future headphone choices, and get an estat!

This is an even better deal, and excellent posted general spec info, over what iFi Audio provide via their iCan/iDSD with ESL combo!
