Products you added to your system in 2021 that made most impact to your music enjoyment

As 2021 comes to an end, just thought it would be cool to share some of the most impactful audio upgrades in your system this year?
Here’s my top 5 list…

1. Pass Labs XP-12: Upgrade path was from Rogue RP-1 to Rogue RP-5 and then to Pass XP-12 that was the final touch. Huge improvements across the board. Mates well with my Rogue ST-100 tube amp.

2. Phono Cartridge: Goldring E3 MM to Hana EL MC. Clarity, presentation, dynamics in spades!

3. Phono Pre: From the built in phono pre in RP-1 and RP-5 to MoFi UltraPhono to Sutherland KC Vibe MkII. Lowered noise floor, increased resolution, dynamics. The KC Vibe MkII is almost double the cost of the MoFi and it’s the one of the few upgrades where an improvement was proportional to the cost difference. At least in my system. Records that seemed noisy become more listenable. A great little phono pre. 

4. Audience AU24sx speaker cables. These speaker cables are a clear window into a recording. Nothing hidden, nothing exaggerated. 

5. Power Cords: Acoustic Zen Gargantua for preamp and amp. Lower noise floor, increased resolution, natural sound, expanded soundstage

Honorable mentions:

1. Acoustic Zen Absolute Copper interconnects. In my opinion the AZ cables don’t get the respect they deserve on these forums anymore, overshadowed by some of the “flavor of the day” newcomers (without going into specifics on brands).

2. Puritan PSM156 power conditioner. 
3. Supra Cat8 Ethernet cable.

4. Lumin U1 Mini

5. MoFi LP#9 Stylus Cleaner. Better than the Onzo ZeroDust although I still use the Onzo between the sides. 


Vpi tt prime scout upscale audio version package, Hana SL cartridge, acrylic dust covers for my SMe10 and Vpi I bought them from Gary , Schiit Freya plus preamp, tubes tennis ball 6sn7, and uk version, Tellurium phono Cables Black, Carda pc clear reflection, and new phone cable for my SME10, Lots of FIM cd label, and SACDs and vynils.


I did try Acoustic Zen Absolute Copper speaker cables. Unfortunately they didn’t work out for me in my current system.

Replaced my Audio Research SP6B, in continuous use for 40 years, with a used Cary SLP05 with ultimate upgrade. Had no idea the improvement would be this great!

Tone Poets, Blue Note Classic Series and Acoustic Sounds Series LP reissues.

Denafrips Pontus II DAC but I might be cheating if it was Dec'20.



Enjoy reading what others have done. 

1.  VTA Passive preamp with TungSol 12AU7 buffer tubes.  Really nice sound.  Tubes and horns are the way to go??

2.  Springs under the subs and speakers.  This was jawdropping.  Cost $100 for all. 

Reasonably priced tweeks really gave me the bug!!  More plans for 22.
