Best kept secret in AC line filtering conditioning

Has anybody here tried the RouteMaster? I just ordered the Ground Master City to use in my apartment so looking for good things to come from that this weekend. The RouteMaster sounds intriguing.

Iv tried a Ton of diffrent Power conditioner,

The best iv heard comes from Ralph @ Atma-Sphere i purchased a unique that was bought up to spec, it was the Elgar 3000b Its massive and was built like a Tank this made a massive diffrence in line noise, However the voltage was not suitable to the country i moved too and had to sell it off. This was one of my biggest regrets.

No other came close to the Elgar untill now the Puritan Labs, I would still say the Elgar is a better unit but this is easier for USA buyers to use.

I just got my PS Audio P12 regenerator setup and it has made a dramatic difference, especially to my analog setup. Whereas before the P12, I had a slight amount of audible noise when playing records (easily confirmed by just switching the input) that noise is GONE with the P12.

I've not used a conditioner before as I figured I'd "go big or go home" on AC line filtering. Glad I went big.

The PSM 156 is in my system now. I recently removed a PS Audio P20 and before that had a Niagara 1200 and then 3000. The 156 is the only one that stopped transformer buzzing from a couple of my amps. Taking it in and out is quite dramatic as our power here not only has DC on the line but also quite a bit of noise. The P20 was fantastic but my system with the P20 was warm, rich, wide and deep sounding. With no conditioner or regenerator the sound is quite bad in my system. It goes flat, hard, gets a bit harsh up top and has no emotion or anything about it that sucks you into the performance. The 156 is doing wonders for me and also keeps it sounding at its best 24/7. No more sound fluctuations, no more transformer buzz, and a complete inky black dead silent backdrop for the music to appear. The 156 is the real deal. I am using it with the Puritan Ultimate Power Cable. I really enjoyed the P20 but sold it when I had my wiring redone in my listening room. I assumed the rewire would be all I needed. I was wrong as the days that followed had the system sounding flat and quite hard sounding. No life. I installed a 156 (had it for a week to demo) and knew within an instant it would be staying. It does similar things to the P20 when it comes to noise but is a touch more lively vs the P20. I hear more inner details with the 156. Without question one of my best HiFi purchases. My wife noticed the sound was much flatter and harsher when I removed the P20 (she wasn't aware it was out yet and asked why the system sounded so harsh and flat) and we listened for four hours after we put in the 156 and were so happy that the magic was back. This will only help those with bad quality power, and the 156 made it clear that our power is awful for an audio system. My amp sounds best plugged into the Puritan. When it goes to the wall I get a transformer buzzing from my amp (Luxman 595) and into the puritan, its dead silent thanks to the DC blocking. Well worth the money the 156 even if paying full retail (if you have suspect power). 

PSM156 is very good. All my source components are plugged into it.
With the amp it’s a bit more interesting. I don’t experience the transformer buzz and have my Pass XA30.8 amplifier plugged directly into the wall which results in slightly more dynamic sound and more presence in the bass. Plugging the XA30.8 into Puritan I get lowered noise floor, ever so slightly leaner bass, more relaxed presentation and because of the lowered noise floor the details emerge out of a blacker background which in turn produces slightly better soundstage, wider and deeper. It does sound less punchy though. I don’t use stock puritan cable (bottom of the line model) that was included with the PSM156. Power to Puritan is delivered by the Audioquest Hurricane.
