Here's a portable music player that sounds like the best combination of DAC and tube amp that I've heard. It's not cheap, but the sound is ultra-clean, smooth, and very extended.
I moved the a new studio and after acoustic treatment i found a -12 db drop at 128-140 hz ,especially in 130hz,all the rest are pretty good.
when i get up from my listening point i can hear it louder when i seat down its -12db drop again...:confused:
i got a big room with high sloped...
