yes, happen quite often when there is RF interference in the roomSo some hum/hiss when nothing is connected to the amp is normal, correct?

How is all your gear arranged on your desk/rack? I had a ZDT Jr. before I had the 1Amk2. When I first got it it had some hum and hiss like you describe. It's first position was right next to my external HDD. Moving the ZDT Jr and the HDD about 2 feet away from each other solved the problem. If your 1Amk2 is close to other electronic gear, give it some physical separation and see what happens.So some hum/hiss when nothing is connected to the amp is normal, correct?
Hmm I have my amp positioned on the floor less than a meter away from my PC which is also on the floorHow is all your gear arranged on your desk/rack? I had a ZDT Jr. before I had the 1Amk2.

An ifi iDefender+ seems to have reduced the hiss/hum by quite a bit, but still not silent (this is at the lowest impedance setting)

I haven't tried any of the open-backs with it, just the Atticus, which I've also listened to on the Echo MK1. I do have an Auteur on the way thoughHas anyone tried the HA-1A MK2 with all open-back ZMFs? I am looking to build a system around the ZMF open back trinity and considering it as the main amp. The other options I am looking into are the Liquid Platinum, Hagermann Tuba and Feliks Echo MKII. I have posted/will post a similar question in their respective threads, not to hijack this one. Any thoughts/suggestions are most welcome. Cheers!
The Atticus slams even harder on the Cayin than the Echo, there seems to be more sub-bass as well. I do have some hiss/hum though which may be caused by the stock tubes, which are apparently not that good. The Echo had a much blacker backgroundHow do you like it with the Atticus? And could you please give me a heads up once your Auteur arrives? Thanks
Sure I'll let you know how I get on with the Auteur once I've had time to listen to them properlyHow do you like it with the Atticus? And could you please give me a heads up once your Auteur arrives? Thanks
