@Andykong When do you think you might be able to post specs? Also, is there a unit circulating to some reviewers? I’m very interested in this amp, but would like to learn a bit more about it. I have no doubt it will sound great, but I’m an engineer so Specifications are important to me.

Translation WIP, give me a week and I should be able to provide more technical information with specification.

Earlier version of Cayin KT 88 amps are good for switching between modes and tubes as well.

The retail price in China(!): 13,800 yuan. So 1,783.55 Euro or 1,963.32 USD. Without a doubt it will cost much more abroad.

thanks for digging this up! $2K was about what I was expecting. Hopefully not much more or it’s big brother will steel sales.

This is the Specification of HA-6A
The Power rating is a bit complicated because the choice of Power tube, phone out impedance and TR/UL mode will have an effect on output, so please be careful when you go through the numbers.

I said the HA-6A will be priced "round the middle point between HA-1Amk2 and HA-300" previously, that was a big hint on the suggested retail price.

The suggested retail price of HA-6A is US$ 2399.00. The amplifier will be pre-installed with a matched pair of Genalex Gold Lion KT88, and we'll include a matched pair of Electro-Harmonix EL34 EH in the the HA-6A package. In other word, you don't have to choose your prefer power tube, you own both options immediately and you can tube rolling as soon as you finish taking your open-box photo.

The net weight of HA-6A is 19kg, so the shipping weight will be around 25kg. No matter how carefully we packed up the tube amplifier, there are still occasional damage report during the logistic process, almost inevitable for heavy tube amplifier like this.

I am so looking forward to impressions vs the HA-300.
The 300 has been my goal for awhile, but cost savings in as beautiful of a design that may be even more versatile for headphones specifically is very appealing.

Thanks for the specs. It’s a beast alright. Plenty of power for most headphones and enough weight to ensure at least a broken foot if you drop it.

The HA-6A has incurred the proven amplification design of our HA-300. The tube amplification part of the HA-6A is single-ended Class A, and then output from Power Tubes will feed into a pair of output transformer to provide genuine balanced driven output (both XLR4 and 4.4mm). The single-ended RCA input will feed into the Tube Amplification section directly, but the Balanced XLR input go through a pair of input transformer and converted to single-ended. The functional diagram of HA-6A will show the signal processing path clearly.


So to clear the doubt. Yes, the EL34 and KT88 are operated in Class A Single-ended, but the XLR4 and 4.4mm are truly balanced driver, they are NOT hard wired from single-ended phone out and they sound very different because of our Transformer coupled design. Will single-ended tube amplification sounds good with balanced headphones? Definitely if you implemented this correctly and Cay in HA-300 sustain this claim. The design and quality of output transformer plays a very vital part in this approach and Cayin has a very unique advantages in this aspect: we are one of the very few, if not the only, headphone amplifier manufacturer that incorporate transformer design and production in-house. We can design the transformers to meet the need of a specific amplifier, and wind the transformer in house exactly as design even when we are making high-end amplifier in small production batch.

While finding an off-the-shelf transformer for speaker based amplifier is probably not very complicated because the loading and output features are quite homogenous. However the output transformer of headphone amplifier are much more complicated as we need to take care of headphone loading from 8 ohm to 600 ohm, so being able to design and build transformer that meet the design of the headphone amplifier exactly is an significant consideration.

@Andykong let me raise my hands very high to show my interest if this 19.5kg amp is going to be doing a review tour (in Australia)

If you are thinking of one, i’m happy to give you full details of my gear at home which would work well for the meat/comparisons within a review that I would do

i guess the postage won’t be too cheap

just putting it out there

I was one of the luckiest that had the chance to test it matched with the Meze Empyreans at the last Shanghai Canjam and I must say thank you to Mr. Andy for having allowed me to listen to that match as long as I wanted.
In my opinion it was one of the gears that during the show was totally overlooked.
I haven't seen anyone posting anything about that after the show.
Anyhow, that combo was an instant love for me...... simply superb!

I will take advantage of the coming Chinese New Year festival to visit the dealer in Shanghai to see how it works with my Focal Clear: I am seriously interested in that amp...

In case other local fellas are interested, the unit is available at the below dealer.

Any update on this being released to the general public @Andykong ?

 

[Faber65]

Well, I am not Andy, but let me try to give you a rational answer.
The 24th we started the Chinese New Year holidays, so no local company would make any announcement before.
Then almost the same day the Government started to take countermeasures against the nCoV and now the only thing that we know is that we (at least in my area) will start working on February 10.
So, realistically we won’t see any official announcement before that day.
In the meantime....... enjoy the music!

it's on the website though isn't it - though not for sale through it.

you probably already know that
