I have the old Beyerdynamic DT 990 (modded) and the old DT 880. Both are the old 600 ohm version, and I have grey velour earpads on both of them.

As a headphone amp, I have a Amity HPA 2

Now I am trying to decide, if I should go with a new headphone amp, the MG HEAD OTL, since I prefer tubes, or get a new Beyerdynamic DT 880?

Can't afford both at the same time.

So what would you suggest in buying first?

Thanks
