Let me take a moment and provide an example why I think having a solid foundation of power, cables, and vibration control lets you replace gear and have the new gear work at its best, or close to it, right from the start.
I replaced my Pass XP-20 preamp Wednesday morning with the new XP-22 preamp. This is the upgrade of the 20 with an improved umbilical cord, volume control, and some other circuit tweaks.
The power and cable foundation for the system is three dedicated 20 amp circuits; one for each amp, and one for the source gear and preamp. The source and preamp are connected to a Shunyata Triton v3-Typhoon power conditioner. The preamp is powered via a Shunyata Sigma Analog power cord. The source inputs are Shunyata Zitron Anaconda XLR, and the output to each amp is a Shunyata Zitron Anaconda XLR.
The vibration foundation is a Mapleshade Samson four shelf maple rack that weighs 300 pounds empty, along with Mapleshade Micropoint Brass Footers for the preamp. The rack sits on a ‘wood’ floor over a concrete slab, which sits on the ground.
With this foundation I was able to install the new preamp, and it has been sounding great since I turned it on, and as it gains hours (60 as of now) it sounds better and better.
Since the XP-22 has a new, longer umbilical cord, I placed the power supply on the floor, and the preamp on the brass footers. With the XP-20 the preamp sat on top of the power supply, and the power supply sat on the brass footers.
Anyway, with this foundation I know I can add any other preamp made (with balanced input/output) and expect it to perform at, or near, its best right from the start. The same applies to the file player and the amps.
