I have both. Ultimate outlet mostly impacts and cleans upper frequencies, making the soundprint more detailed and faster. The P300 powerplant has a different impact: it makes the sound more palpable and gives weight to instruments, increases microdynamic, closer to live music. P300 is a very worthwile ivestment for source components. It makes my ML 39 a very analogue sounding source, and my Alesis Masterlink to be a fairly enjoyable component (without it especially the last one could be very annoyingly boring sounding machine).
Ultimate Outlet vs. PS Audio P300
I really like the sound of the two High Current Ultimate Outlets in my system (Krell Integrated and Krell 300 Cd Player, VPI Scoutmaster turntable with SDS and periphery ring, Apogee Stage speakers) and was wondering whether the P300 Power Plant upgrade is worth pursuing as an upgrade. My only priority is sound quality. Will the sound improvement be subtle, is it mostly related to dynamics, or will the sound improve in all areas? Thanks
