The PA400 is a great step up from the SMSL AO300 and A300. Imaging is perfect with a great center. Power is amazing with nice tonal balance. Makes my JBL studio 580s sound like new speakers. I always thought the horn was too bright, turns out I just needed better amplification. Running a single amp in stereo, XLR connected from Topping e70 velvet (also great). Apos is great, many great purchases from them over the years. Try the amp and you'll keep it.

Quick and easy!

I received the Burson in a timely manner. The whole shopping experience was easy and quick I'll be back. Thanks !!

All very smooth . Good communication and help. Well shipped, which was great for me as, uk based.

Shipping was fast and on time. Great company to work with for your headphone needs.
