AIYIMA A80 Stereo Amplifier & DAC Review

[uwotm8]

Amplifier sports PFFB design which should largely do away with load dependency but some remains:

Amir, did you test frequency vs distortion, the most lovely part of budget D amps poorformance performance?

Regarding PEQ and subwoofer HPF - remember this has analog inputs, which are not going through any A/D conversion. So adding either of those options would add a fair bit extra complication.

Well a subwoofer HPF could be analog...

 

[Guddu]

Maybe a stupid question but I'll ask it anyway. Does the remote control also control the volume? Reasonably, it should be so, but I take the opportunity to ask.

It does.

I don't think PEQ makes sense with a device like this, but analog subwoofer-HPF is a problem that has been well solved for over 40 years, as are external active crossovers for little money.

100+ watt stereo amplifier plus a transparent DAC for under $200 with a nifty VU meter display to boot, what more could you ask for? I voted Great!

True, if I could ask, an enhanced version with variable lowpass subout and varible highpass plus PEQ filters for $300, something like the Wiim Amp Pro on stereoids.

Does this have a digital output?

Does this have a digital output?

Of course; the entire unit is digital. Please note the 'aux out' jack on the back.

There is no digital output on Aiyima A80, aux out is analog out.

? I doubt it. Probably an analog out. Surely a digital out would be marked as such.

The aux out will be analogue.

I’m only aware of one amp+DAC (I’d even take the option on just a single device) with sub/aux output that offers a high-pass (w/ toggle on/off) option: SMSL A300. Are you aware of any others? If so, please share.

Let's invoke @sarumbear , that might be watching us from wherever he is

Integrated stereo amplifier with bass-management?

Note: I am not looking for a solution for myself. I am simply doing research, which may result into a list of amplifiers that members who may need a solution that fits to the following specifications may benefit. Hi On the Emotiva speaker review thread a discussion has started on the...

I stand corrected! My apologies, I was looking in the wrong place.

RSL iA255.1 has integrated DAC, sub out and an optional 90Hz HPF toggle.

 

[Multicore]

The design is excellent given the wide high res display which can show levels, spectrum, etc.

Vectorscope?

This VU Meter is Autism gore!
Why has the needle and the Arc segment with the scale not the same origin.

I hate it so mush

Otherwise its a fine little amp

 

[Berwhale]

This VU Meter is Autism gore!

I love the turn of phrase, but it's not triggering anything for me, maybe if I saw it moving...

Oh no! You're right!

Curious… NJW1194 isn’t a DSP . It’s a digitally controlled analog circuit for volume and tone control.

 

[amirm]

Wait they go from the USB DAC straight into another ADC then in the DSP and then convert it back to analog?!

No. it is digitally controlled but analog block:
