I use this open ear headphone amp from Sennheiser and it works great (haven't tried it on bigger speakers yet). No noise, no distortion, Bluetooth works very well. I particularly like the tone control feature, which my previous unit lacked. I swapped out the tubes for a couple of expensive ones, there was no difference, so I think I can save money until the standard pair burns out. Highly recommended!
