Cayin / Sennheiser Package Deal HA-1A Headphone Amp Plus HD-600 Headphones, price drop

PLEASE STOP WITH THE LOWBALL OFFERS. THIS IS NOT A CHINESE AUCTION. This is the FINAL price drop. The amp is better than new and I have put effort into getting it that way. I have over 30 years experience with repairing tube gear, if you are concerned with the workmanship or my claim. Reducing hum is not your typical tweak that has no electrical or measurable effect.

Cayin HA-1A headphone amp: I purchased this unit used and it is in good condition. The photos show the case not secured, as I just changed output tubes to brand new JJ EL84's, which are included. I also replaced the 12AX7 input tube with a new JJ ECC83. The driver tube is a USA Tung Sol 12AU7.

The unit had a slight hum from the factory, you will see that in reviews. I have modified the heater grounding scheme for the EL84's to balance the hum out. It is much quieter than stock.

This is a killer headphone amp. It has a ton of gain and can even be used to drive efficient speakers.

The Sennheiser HD-600's are almost new. I am the first owner and they have less than 2 hours use.

Original boxes.

This is a great way to get into a headphone rig and save a few bucks.

Paypal preferred. No fee :)

Shipping is extra - provide your zip code so I can estimate. Depending on your location, I may be able to include it for free.

I have rated the combined setup 7/10 - the Cayin is not new and looks slightly used - it has a finish that shows dust & dirt - I have cleaned it well. The headphones are 10/10 perfect.
