If these amps keep getting more and more powerful, we can only use it to power speakers. Then we just duct tape two speakers to our ears and call it TOTL headphones, for sale at the low low price of $4,999.99!

I cannot see any 17bf11 NOS tubes to buy? Is this a very uncommon tube?

 

[OhmsClaw]

I do think that the price gap between this and the 3A is going to be interesting. What the 3A is going offer over the 2A?

The types of tubes you can replace/roll. That's effectively it. (And 300$)

That's what Raal is for

. . .and the different sound sigs that come from them. I am sure they will be two different flavors of awesome.

Cayin knows good sound.

I'll look out for this in the UK.

A comparison of this against the Russian Shortest Way 51 SET would be interesting.

Cayin are doing a superb job, really well built units, I have an HA 3A and love it

 

[DavidSerig]

If you wish to send one unit to Florida for sunshine and listening, I have not been to Beijing since 1980.

 

[Monsieur Dionysos]

Cayin makes great headphone amps but I wont sink any money into them until they give me a pre out.

 

[Syan25]

Oh yeah, that is to be asked for.

We have dealers in US, MusicTeck from New Jersey and ZMF from Chicago carried our desktop headphone amplifiers.

The HA-2A with and without the tube cage.

For the record, the tube cage protect the tubes from any physical contact, and it will also reduce the RF interference significantly. Therefore whenever you experience some sort of interference, its always adviceabe to put the cage back and try again.

That's a great looking amp.

 

[LXMc]

That's a great looking amp.

Definitely agree - the proportions between the chassis, tubes, transformers and dials/switches is very nice. Really interested to see how this performs and lines up, not only with HA-3A but stuff like the Icon HP8.
