If you don't need the DSP function, I would advise against it. It also has very little power, as many of the components are undersized.Hey guys I want to use the Bru5 as a power amp to power rear surround speakers. Will it be ok to run it that way off of a vintage Rotel rsp-1068 preamp??? The rsp-1068 has bass management and contour settings for each channel. I am 2 seconds from ordering it but I already hate that I have to wait at least 2wks from Ali and I don't want to go through the hassle of sending it back if it won't work as a power amp from a pre. Any input welcome. Thanks fellas
From what I read it seems it has plenty of power into 4ohm with the 48v 10a power supply. Is that BS???If you don't need the DSP function, I would advise against it. It also has very little power, as many of the components are undersized.
I would rather go for the AIYIMA A07 or Fosi V3 if you want something cheap, or the new Douk Audio A5 with PFFB.
You have to choose the power supply output from the tables according to your requirements.

I have speakers with 8" chassis and 93 dB efficiency, 30 watts is enough to make people run away, something like that has zero meaning.I just read it in this thread somewhere. Plus I watched some YouTube vids. One of them a random guy who was powering big 8in bookshelves to ear bleeding levels and they sounded damn good. I'll be powering 4in 2 way Canton Plus S mini satellites. 4ohm, 89db sens, rated 90watts recommended. They will be used as read surrounds in a 4.2 setup. I have a crown XLS 1002 powering 8in 2 way Camber fronts. I figured a tpa3255 amp should have plenty of juice for these.

Yea that's what I was trying to save save as much $ as possible since it's just for the rears. I think I'm just going to go with an Audiosource Amp100. Should do better then both of those choices. The Bru5 with aiyima 48v 5a would be $50. Just found a mint audiosource amp100 basically new for $38 with shipping. That's a no brainer. Thanks for your input brother. Appreciate it.I have speakers with 8" chassis and 93 dB efficiency, 30 watts is enough to make people run away, something like that has zero meaning.
The TPA3255 is just an amplifier chip, there's a bit more to an amplifier.
The high-quality output coils used in high-quality TPA3255-based amplifiers alone cost more than the Bru5 and that alone significantly limits the performance.
But the Bru5 should be sufficient for your intended use.
48V/10A is completely overkill for the Bru5, the amplifier can't do anything with that. 48V/5A or better 36V/6A are more than sufficient.
A Fosi V3 with a 32 or 36 volt power supply should be a better choice than the Bru5 with 48V/10A. Price difference?
Side note on Audiosource amp: I have close to a dozen of these Amp 102 (not 100), 200, 300, sub210, driving in-ceiling and in-wall speakers. Measurements are probably average, and they are inefficient (class AB… but I heat my house 8-9 months a year).Audiosource Amp100
