This is DIY but may live elsewhere and I need to work on the title to get a nicer Acronym. I've been dreaming about for this for some time and having gone through various iterations of ideas that ultimately failed I ended up with this one. Your caveat is that it is a Spice Model without the...

Hi all, I have a Bel Canto S300 with one module that is out of commission. I was going to try a warranty fix but then I see how simple the replacement would be to do myself. My 1st thought was to replace both modules with new ones from parts-express. This is the closest match I could find...

Hopefully this post is helpful/interesting to others and not just myself. I have recently purchased an SMSL A300. It suits my needs quite well, but I am hoping to extend it's functionality. Years ago I had a speaker tap cable made so that I could drive headphones directly from the speaker...

After successfully implementing the tube-hybrid mini amplifiers Aiyima T9 and T9 Pro (and an unsuccessful test with the Nobsound B100), I was curious to give a tube-less mini amplifier a try, and my choice is the Loxjie A30, which qualifies as an all-in-one budget solution with enough inputs...

About 12 years ago I bought two KingRex T20u amps for 270 € each in Germany. I liked the size and the simplicity of this amp, and it had exactly the features that I needed. Now that I have discovered ASR I would be interested how the Kingrex performs in terms of measurements. As this product is...
