Slew Rate (typical) 14 Volts/microsecond.

Small Signal Bandwidth: typically wider than 5 Hz to 100 kHz at -3 dB points.

Output Power: greater than 50 Watts per channel into 8 Ohms.

Money will get you a 50wpc Akitika GT 102, If you really want to build something, the same amount of The amps designed to have a particular sound and be used with high efficiency speakers. Both cost good amount of money so please donate generously using: So I need hire a bodyguard and get some serious insurance for my bodily parts from Loyd's of London. I suspect the above review is going to make me many enemies in DIY audio circles.

We are not even close here folks.ĭo I need to tell you that I can't recommend the Pass ACA for hi-fi listening? I hope not.Īs always, questions, comments, recommendations, etc. Amplifiers need to have a lot more power. Build it, have fun with it and then put it aside and get a proper amplifier. Yes, the amp started to cry when I turned it up much but until that point, it left the ACA so far in the dust it was not even funny.Īs a starter hobby amplifier to get some sound coming out of a speaker, with relatively few components, the Pass ACA Class A Amp does the job. Now the speakers came alive, with lots of bass, great dynamic range, and detail. And this was with my Topping DX3 Pro at full volume.įor grins, I plugged the US $74 tiny little SMSL SA100 Amplifier which I recently reviewed into the setup. Granted, the Concertino is spec'ed at 86 dB efficiency but come on, I could barely hear it. Is this thing on? That is the expression that immediately came to mind after I hooked up the ACA amp to my Sonus Faber Concertino bookshelf speaker. I am told that version 1.6 which I tested now has a spec of 10 dB for gain so we are good.ĮDIT 2: See this link for bridged mode measurements:

Nelson stays with 1 watt output which shows the performance to be better.ĮDIT: I noted on the dashboard that the gain was much lower than the spec. So this is what the unit is supposed to do.
