It's a replacement amplifier query and not really something I feel at all confident about building.
My old faithful Kenwood L-07M monoblocks are on the way out. One is still OK but the other is pulsing and sounds awful.
I have to add that despite their age these were the best amplifiers I personally have ever listened to.
Looking for a new amplifier how important is bandwidth in selectiing something as a replacement?
Using a couple of dirt cheap Fosi Audio in the short term and they sound like crap but my audio budget is a bit limited as I have splurged on a set of drivers for a new project.
Looking at sales sites very few makers are stating what their bandwidth is on retailers pages, Rotel being one of the few I have found. So are the new Rotel amps any better than the older models as far as speed and bandwidth go as they are just within my budget.
I don't need a lot of power as these would just be for the tops on my system in the loungeroom and the bottom ends are covered by Rotel already but quite old models the RB1070
 
Mainly because the only feller in Australia who was supposedly competent at working on these doesn't seem to be around any more. RestorerJohn over at ASR hasn't replied to any of my messages and I don't know if he is still around. Nobody local wants to even open them up and have a look.
I'd love to get them fixed. I bought them from him over twenty years ago and have been solid until now
