dozen of those little "fart in a whirlwind" Alan Maher parallel filter PE series conditioners prior to the addition of the UberBuss. The parallel filter UberBuss is the whirlwind! Cheers,Robin Cheers,Robin
I assume it's OK to ask Buss-specific questions here, Danny?This is really hypothetical since I don't own a Buss (yet ) or a Torus, but would there be any benefit in combining a Buss with a Torus or Richard Gray Substation-like isolation transformer.I'd think that the power delivered from an iso tranny is as good as it can get, but maybe this is a naive notion?I'd also guess that if one did combine them then the Buss would go after the iso tranny?Any experience with this type of set-up?And while I'm here, is it OK to plug digital sources and amplification into the same Uberbuss, or will the AC nasties from the digital then enter the amp via the Buss (or are the outlets in the Buss isolated so that the digital won't interfere w/ the amps). Or is it best to run the digital gear on its own Buss?Thanks for any info!-Mike
If you have a particularly noisey system (like a Sunfire amp along with a complex digital front end) I can add more filtration if needed, but these situations are pretty far between and the stock units work VERY well at isolation.I hope this answers your questions. If not, ask away.dave
One caveat on iso transformers. The ONLY one that I tried in my system that was not current limiting was the Topaz @ 2.5KVA. dave
Are you saying that even the Piltron is current limiting?
In my experience, on BIG SS power amps that are current hungry, yes. Even though toroids are more efficient than an E or R core they have a hard time keeping up with the kind of surges that are seen in some music. Here is an exercise: Plug the amp into the wall and using your ammeter, turn the amp on and look at the inrush current as your amps charge up their filter caps. Then, plug it into an iso TX of any flavor and do the same thing. It helps if the meter has a peak/hold function, but can still be seen on most ammeters. If there is no difference in peak inrush current then you are good to go.There is a guy here that bought a Torus RM 20 to use with a couple of PASS monoblocks and they sounded constipated with the Torus. CAVEAT: I have no experience with the 60, 70 or 100 amp versions, so I'm sure they would 'probably' handle the current. They are VERY BIG $$$, though.Dave
Laura (vinyl_lady) uses a MajikBuss in front of a PS Audio PPP and she's reported excellent results so the Buss seems to work great with regenerative conditioners also.
I highly recommend Danny's free demo(if still available) of the MajikBuss Mike or just save the return shipping cuz you'll want to upgrade to the UberBuss anyways. Cheers,Robin
