        Is anyone using, or have heard Accuphase amps with the SoundLab speakers. In particular, the A300 mono blocks. Cheers.

          Maybe this note from Roger West will be the last word in Power Cables for SoundLab Speakers.

          Hello Eric,

          The major work that we have been developing is a bias supply that uses a miniscule amount of the audio power from the amplifier to develop the bias voltage. This eliminates the AC power cord, but does not have any effect on the sound quality. The major reason for the development is to eliminate the challenges of different voltages and connector types in foreign countries. Further, it eliminates problems with importing speakers that use AC power, which usually requires an inspection. If you do not mind using an AC power cord then the self-bias approach would be of no value.
          Other than the self bias development we have not made any changes since you purchased your speakers 4 years ago.

          I think the operative words are “miniscule amount” of power required.

            @ Bigtwin:

            Right!
            Here’s the thing: if you say that power cords or spikes or any one of a thousand useless accessories makes no difference, they will continue to ask the forum until they find one person who confirms their assumption and gives them an excuse to buy that useless cable or spike. The opinion of design engineers and professional musicians is of no interest to them. They care about being able to do something with their system, for listening is not enough fun.

              Roger West told me “the SoundLab speakers don’t require a look of power. No special power cord is required” That’s good enough for me.

                For those interested in a more robust power cord that is custom configurable, I have worked with a reputable high end cable manufacturer to develop a replacement cable that truly looks and feels the part to power your SL panels. The five foot set pictured utilize high quality right angled connectors so that the cord lays flat coming out of the IEC and is directed downward from the wall outlet. However, other lengths and connector options are available. Here are the specs:

                12 AWG 3 conductor twisted design
                High purity stranded copper for maximum conductivity
                Premium UL 62 grade jacket provides excellent resistance to abrasion, water, oil
                UL listed and CSA certified
                Temperature range: -40 degree C to +90 degree C
                Voltage rating: 300 Volts
                Amp rating: 25A

                Connectors:
                Male – Marinco 8215 NEMA Hospital-Grade Power Plug 15A 125V
                Female – Marinco 320IEC15 IEC Power Connector 15A 120V
                Wattgate 15RA Right Angle Adapter

                  Hi Dizzie,
                  Yes, I tested three power cords differing in geometry, construction and price (double-blind test).
                  No audible difference here.
                  Regards
                  Massimo

                      Massimo,

                      Thank you. You saved me a lot of money and gave me one less thing to worry about.

                      Has anyone experimented with power cords on Sound Labs? I am interested in your results.
