Yes, good idea thanks - if it is subpar I will definitely return it.At the risk of some common felt disappointment to you I have just read that the rca on the A07 Pro is sub par to the standard A07 but the bluetooth is supposed to be outstanding...well at best on the same scale of quality as the standard A07 RCA output. Suffice to say if the A07 Pro does dissapoint then you could always return it and maybe grab the newly revised version of the Fosi Audio TB10D. The second revision of that amp has got rave reviews from the CheapAudioMan on Youtube.
Though, I didn't seem any measurements of the A07 Pro - just someone opinions about the RCA on the A07 Pro in a different thread?
