PS some of my shopping has turned up and during the wait some of my shopping I have found much cheaper elsewhere.
The 4 mic respeaker clones are extremely cheap.
2 Mic module is prob not worth the few $ saving apart from the speaker out that is good to get you going.
I am waiting for quite a ‘nice’ usb dac but still waiting for the el cheapo PCM2704 usb which supposedly sound pretty good.
My Sure Electronics not 100watt Class-D amp turned up .
What a quality module that is and I will be using the mute and standby pull to gnd pins on it.
It really is excellent quality but the extra $20 dollars over an el cheapo TPA3116 is sort of hard to justify.
Its 100watt into 2Ohm with 10% distortion I run from the max of 24VDC and get 48watt that is pretty damn clear and boy is it loud.
12Vdc prob would be OK it would halve the wattage but ears work on a decibel scale not linear so it doesn’t sound half the volume.
I rarely have the volume above a third with 12v a guesstimate 50% volume would prob be your norm.
The Pi 3.5mm is a strange beast and on average isn’t that bad sounding then you will get a track where you will wondering if the amp or speaker is dying with the distortion on the vocals.
Dunno what it is the method of recording, frequencies in the track or sample rate, VBR or CBR but anyone listening will cringe.
So it wasn’t the el cheapo TPA 3116 and now understand why the Pi gets such bad rep for hifi audio unless you use a dac, but those are cheap and plentifull also and in comparison sound sweet,
PCM2704 usb stick or board and TPA3116 all can be got for $6-8 apiece!
But must say My Sure Electronics Wondom board is a quality piece of kit, so no sulks about its purchase due it really being the Pi.
I presume the respeaker 4 mic clones are just treat as respeaker and grab there git hub drivers.
I have an respeaker on order as hadn’t noticed the availibility of the clones.
My 30watt 8cm speaker is a great compliment to the Amp and copes & sounds well produces a good full range with quite good bass.
Still waiting for the Techtonic MBR horizontal speaker is like the wondom and justifies extra.
Its 20 watt in comparison and quite a bit more than the good quality Visatron, dunno on that one yet. The quality of the Vistron and 10 watt more means this might be worth it or not.
