Aiyima TUBE A3 PRO preamp - Boost your amplifier with prime sound and EQ (review)
That preamplifer has really impressed me! I think I found the way how to equalise the signal from phone via Bluetooth before the power amplifer, and get the best possible audio from it..
.. this is the way how you can change eq from your youtube music streaming via Bluetooth and the 6J1 tube valves makes the audio signal even stronger and more pleasent.
