If you want something to match the Esoteric amp, I would recommend the Acrolink cables. They were designed for Esoteric Audio products. I use an Acrolink power cord on my Esoteric SACD player and it works magic. I paid 400.00 used for it and it retailed for a little over a grand.
Esoteric A-03 power amp - suggestions on a power cord.
The Esoteric A-03 is a 50 watt Class A 90 pound beast and need some ideas on a power cord that will handle that current / drive and not limit the amp's capabilities. I would like to hear from owner's of this amp or other members who have Class A amps. Purist Design who makes wonderful cables and run by a great guy ; Jim Aud need not apply as to my ears they made the sound too thick and slow. ( to me ) So look forward to some seasoned responses.
