I also have a EquiCore 1800 and DeepCore 1800 and was surprised at how large a difference it made. I was living in an NYC apartment at the time.
There is a used pair for sale for $1800 on another site right now.
Looking for the best power conditioner or regenerator or any product like it for under 2k.
As usual I can find a ton of things recommended without much comparison between them. I am currently looking at the equi=core line, deep=core, niagara 1200, nordost QB8, and the MC line from high fidelity cables. Completely open to any other recommendations. If anyone has had the chance to compare any of these, please let me know your findings.
