Power regenerators on pre / digital - any downsides?


Hi all,

I get the problems with driving power amps from mains regenerators, this can dull the sound if the unit can't provide enough power. I've had my sound utterly ruined by mains filters too, strangling my amps. 

So on to the question, is there any downside to regenerators for pre amps and digital kit, i.e. those units that don't draw much power? I see a lot of interest in power cables but I was thinking about fixing my mains. 

Thanks, Tim

I'm using a power plant 3 for my streamer, DAC and preamp and noticed a nice improvemennt. I have a solar system on the roof and I don't think the inverter generates particularly clean power. The PP3 made everything sound a bit clearer. 
Thanks v useful! The lower power ones are cheaper and could be worth a try so considering Dac / Pre for now. 
Everything, including 350 watt mono amps, is plugged into a PS Audio P20.  Sounds great.  It barely moves the needle on the P20.
I like a regenerator on my pre and DAC, but it also works for my 300 watt mono amps, too.  You just need a big one!  I am using a PS Audio P20 and find it delivers very consistent musical performance in my system, and no digital hiccups during air conditioning season (was a big problem for me before!).

Yes, but that's just how it seemed to worked out for me.  Also, during the upgrades, cabling was changed too. 
Thanks, I want to avoid using one on my power amps. So I guess you're saying that the regenerator became unnecessary when your kit got high end?  
I used a PS Audio Power Plant Premier for a few years.  When i first got I plugged my VTL 300 Deluxe mono blocks into it.  It sounded weak and anemic.  The PPP did well with the front end gear I had at the time. As I upgraded to better gear with much better internal power supplies the PPP became just a nice way power up my gear in one shot.  I don't use the PPP any more, I have multiple dedicated circuits.
