Re: Building a DIY amp with NVA amplifier boards
Posted: Thu Feb 06, 2020 5:15 pm
When i used diy Avondale based amps and B&W P4 (still got them all )i moved the crossover filters actually inside my amplifiers This is how Les W runs his set up (a separate crossover box right behind his amps) and a few others. I tried it and was totally amazed at how much clearer everything was - the window had been cleaned some what.
You have to have a dedicated amp for tweeters though, or biwire from amp to speakers) And don't get any inductors too close to a transformer or huuuuummmmmmm will be the result. After i reported my purely subjective findings a few others tried it and agreed with me. However, there were several who could not think of an electrical reason why anything could be different (it was on pfm after all ).
Anybody who has a dedicated tweeter amp really should give it a go. Nothing ventured nothing gained, it's easy to revert back. In diy NVA land it is even easier. Only the capacitor in series with the tweeter needs to be moved to the amp. I will of course be trying it again when i have lived with the six pack of amplifiers for a while
