    Luddite streams audio.

    The new preamp with BT and RCA inputs works fine. The remote is generic anonymous with many useless buttons, but it does control all preamp functions, turns off output, actual on/off is a toggle switch on unit.

    This works for me with a CD player RCA and android tablet BT nput, RCA output to minidsp for LXminis. This preamp and the 4 channel classdaudio amp replace a HK receiver and chip amp. Click image for larger version

    Ordered 12/14, arrived today 1/27. No longer available on Amazon, either so good it sold out immediately or so bad it's discontinued. I'll get this hooked
    up in a day or two.

    Thanks all.

    I'll update this when my Nobsound preamp shows up and I connect to my LXminis.

    Nice clean build. That huge toroid looks like it was begging for more work to do. Channels 3 and 4 should do it.
    Ever since I built my Leach amp back in the late 70's I have been wanting to try another amp build. Maybe this will give me some inspiration.

    The components are a kit from classdaudio.com. It is a CDA258 kit. Lots of watts. The company has newer SDS boards but they still make these boards. They were popular years ago. The large toroid and power supply can handle two boards for 4 channels or 2 bridged channels. I have read mostly good reviews and one really bad one, of their SDS based products.

    This is a cheap route to a 4 channel amp for my LXminis. I ordered one CDA500 amp board from classd and some connectors from PE. The case is Par Metal (now Pi Metal) ebay store sourced.

    classdaudio products are made in USA.

    Audiocircle had a big thread when they first came out. I have used this and one other classd amp for years. I find their sound quite acceptable. They have been trouble free.

    What amp board is that. That is also monster toroid!

    Hopefully all I'll have to do to fit the second board in is move the toroid over, and drill and mount more RCA and banana jacks. Should be a short thread, with a pause waiting for parts.

    Seems like I don't have any control over pic size.

    OK, it's not a speaker but it is a project, update a Classdaudio amp from 2 to 4 channel.
