It seems Cayin HA-1 is now available here in US. Has anyone paired these two? Would like to know feedback if so.

It does have an impedance selector, so that should cover the K 1000s but not sure if the 2W is sufficient to drive the AKG's.

I just ordered the stax 3030 system but still can't get the AKG sound out my mind. Want to have both systems listen to them for a while and then decide to keep either both or sell what I don't like.

Here is the link to a recent thread on the discussion of this amp - of course there is no mention of pairing it with HA-1.

if it outputs 2w @ 120ohms, then yes, it's more than enough. k1000's are only rated to 1w. but not many headamps put out that much power, so make sure.

Thanks Orpheus. I found the following ratings from a chinese web site. Since I don't know chinese, simply deducing from the numbers ...

¶ú·Åʱ²ÎÊý£º

So it seems it will deliver around 1.3W for the AKG's. Do you think that's good enough power? Is this math above (in the chinese spec) seem to be correct? I recall reading another thread where someone had given an approximate rating of how the power drops as the impedance increase. I remember that the drop was significant than a mere 0.6W drop! Any comments?

Any particular reason you want the cayin? The norh amp is a much more standard pairing with the k1000s.

 

[suharsh]

... the reason for attraction was the various impendance settings you could have - bascially didn't want to have amps for the different headphones that I have / intend to collect. Unless of course my understanding that impedance matching isn't really that important, is incorrect. See, I have an MGHead with Senn HD600, I recently placed an order for STAX 404 with SRM 313 and if I buy AKG 1000 - another amp for it?!?! So my intention was if HA-1 works well for AKG1000, I could use it for the Senns too and then sell off MGHead and in future if I were to buy (which I will - thanks to head-fi) headphones of varied impedance, I could still use this amp.

 

[kartik]

I'm not one to raise false alarms but I distinctly remember a recent thread where someone questioned the performance of the cayin ha-1. If you really want a headphone amp with the power to take on an AKG and the Senns, I would reccomend the Berning MicroZOTL.

Who is it available from?

 

[suharsh]

It's Franz from thetunerguy.com

He is advertising on Audiogon. There was one used on Audiogon just two - three days back if you are interested - around $400 obo.

If you do happen to buy them, please let us know your opinion of the amp.

Happy listening!
