Description

After adding the Pathos Classic One mkIII to my system last week I felt compelled to start fresh rather than continuing from my previous system.  The transformation was so dramatic that it was more than just an upgrade.

My system started with an Integra 50.1 receiver that I still use for home theater.  About five years ago I picked up a Yaqin MC-30L Class A push-pull tube amplifier that I consider to be a high value product and an awesome amplifier.  Keeping a long story short, I got the audio bug again and picked up a Cambridge Audio 840A that was the "other choice" when I first chose the Integra 50.1 receiver.  It didn't take me long to realize that it wasn't want I wanted so I traded it in on the Pathos and the rest is history.

I still use a custom amplifier switch that a EE friend of mine built for me to switch the speakers between the Integra 50.1 receiver and the Pathos Classic One mkIII.  It's not the ideal setup for my stereo system, but it's the best compromise that I have found.  The custom switch uses 10-gage BJC wiring for everything.

The improvement in sound from my Integra 50.1 receiver to the Yaqin MC-30L integrated was significant, but the improvement going to the Pathos Classic One mkIII was even more so.  I really don't see myself ever needing a speaker or amplifier upgrade.  The financial investment that would be required to improve on either is beyond what I would be willing to spend.

As part of a home remodel project I needed to have a new outlet installed for an over-range microwave that was on the opposite side of the wall from my audio system, so I took the opportunity to have a dedicated circuit added along with a PS Audio outlet.  I honestly didn't expect to hear a difference, but figured this was the best opportunity that I'd ever have to take the step.  Admittedly, it was a significant improvement.  I have my APC H15 power conditioner plugged into the PS Audio Classic wall outlet and my DAC, SACD player, and Pathos amplifier plugged into it.

    • Pathos Acoustics Classic One mkIII
    From Pathos Acoustics:

    Integrated amplifier in Class A/AB, hybrid circuit with input tube stage
    2 x 70W @ 8 Ohm, 2 x 130W @ 4 Ohm, 270W in bridged mode (mono)

    Classic One represents a new standard in its price category: it success fully blends in a single chassis a preamplifier and power amplifier, completely separated from each other and provided with their own individual power supplies.
    The pre-stage - or, better, the preamplifier - is purely tube, balanced, pure Class A, extremely low noise, with high intrinsic linearity and without any feedback. It provides an exquisitely tube sound in terms of transparency, air, harmonics and refinement… in one word, musicality.
    The power stage is a solid state power amplifier, high bias current, Class A/AB in order to adequately drive every load. It provides the sound with speed and dynamics, without influencing the tube nature of the sound. The volume control is motorised and remote controlled, the remote itself is in solid wood. Power supplies are over-dimensioned and stabilized. Selected components, pure silver Pathos signal cable wiring, gold plated terminals, high quality materials and refinement at its highest standard are additional benefits provided with the Classic One.
    • Blue Jeans Cable LC-1
    From Blue Jeans Cable:

    The most important attributes of a line-level unbalanced audio cable are (1) shielding, and (2) capacitance. Heavy shielding protects audio signals from interference from outside sources. LC-1 Audio Cable uses a heavy double-braid shield, with one bare copper braid laid directly over another for extreme high coverage and high conductivity to ground. By shrinking the center conductor to 25 AWG and foaming the polyethylene dielectric, we were able to get capacitance down to an extremely low 12.2 pF/ft. Capacitance can be important, particularly in long cable runs, because it contributes to rolloff of higher frequencies. The softer dielectric material and smaller center conductor, meanwhile, make the cable highly flexible and easy to route.
    • Maverick Audio TubeMagic D2 DAC
    From Maverick Audio:

    The Maverick Audio TubeMagic D2 DAC is designed to be a pure dedicated high-end digital to analog converter. The “pure” means not a single unnecessary feature added to the processing circuit. This “minimalist” approach ensures absolute signal purity without any distractions or interference, making the TubeMagic D2 sound very natural without coloration.

    Four digital sources (two coaxial, one optical and one USB) means that computers, laptops, network music devices, media players, game consoles, CD/DVD players and more can be connected concurrently using S/PDIF (Coaxial) , Toslink (Optical)  or USB inputs.
    Two analog audio outputs (one normal analog output and one tube pre-amp output) allow you to connect the TubeMagic D2 to any type of stereo music setup.
    • Pioneer Elite PD-D6-J
    SACD player
    • Nordost Sort Kone AC
    From Nordost:

    The Sort Kone is a directly coupled and mechanically tuned resonance control device, using a sophisticated new approach to the problem of supporting sensitive electronics. 

    Whereas most equipment supports are referred to as Isolation Devices, this actually completely misunderstands the nature of the problem. The most harmful mechanical energy doesn’t enter the equipment from outside; it’s generated internally by the audio circuits and their power supplies. Transformers, power supply capacitors, even the active devices themselves, all vibrate as they operate – and those vibrations occur right where the fragile signal is, creating timing errors that smear and distort the music. The Sort Kone is designed specifically to deal with this threat to audio fidelity.

    Sort Kones provide a “blacker” background to your music. With it comes greater focus, instrumental color, depth, transparency and dynamic range. Your system will sound more natural and more lifelike, your music more lively and engaging, the musicians like better musicians – simply because you’ll finally be able to hear the notes they’re playing, the way they play them and precisely when. So, release the hidden performance that’s lurking in your equipment.

    • Three-part construction employs superior materials in a mechanically tuned configuration.
    • Bypasses soft feet fitted to equipment to provide a direct mechanical ground path for internal energy.
    • Can be used in triplets, quartets or even larger numbers.
    • Height: 56mm
    • Four levels of price and performance, depending on materials employed:

    AC – aluminum post and base in combination with an upgraded ceramic coupling ball.

    • Ayre Acoustics Myrtle Wood Blocks
    From Music Direct:

    Meant to be used in sets of three, the Ayre Myrtle Blocks go between the chassis of the component and the supporting shelf. These replacement feet should be slightly taller than most stock feet. You'll be captivated with the improved musicality these wood blocks provide! 
    • PS Audio Power Port
    From PS Audio:

    The Power Port Classic is our AV Grade high-end AC receptacle that is the starting point for any properly built system. By installing the Power Port AC receptacle in your room you gain an immediate improvement in performance over a standard wall receptacle.

    The Power Port is a custom built, AV Grade isolated ground receptacle that will ensure a life-long level of excellence. The Power Port exceeds hospital grade standards for grip strength, contact resistance and current delivery. Easy to install in your wall, this is one component you need in your listening room as it will help make an immediate improvement.
