Anybody tried Furutech GTO-D2 NCF or e-tp609 NCF?
Power Conditioners
I have about $5,000 invested in a 2 channel stereo setup. Marantz PM7000N integrated receiver, Canton Chrono SL596 speakers, Rega P6 table, blue jeans Canare 4S11 cables. Is it worth it to buy a cheap power conditioner/protector like this
https://www.musicdirect.com/power/furman-pst-8-d-digital-power-station or this
https://upscaleaudio.com/collections/power-conditioners/products/pangea-quattro-power-center
Will I be able to hear a difference/is my equipment sensitive enough to notice a difference; or will a typical surge protector suffice? Otherwise, will it be a waste of money to spend money on a low priced conditioner?
Thanks!

I’m surprised in this thread and some others no mention is made of Sola ferroresonant transformers.I don't see why- ferroresonant transformers make a fair bit of noise in their output, which should be a sine wave for best results. They are good at line voltage regulation, but otherwise make for a lot more noise on the line than the line would usually otherwise have. |
Yes, because the waveform is not sinusoidal. So a lot of higher harmonics will be present that are rarely on the AC line. Electronics tend to be fairly sensitive to the 5th harmonic (300Hz in the US) which is much greater when a ferro-resonant device is used, unless there is a filter to remove the harmonics and thus restore the output to a sine wave. |
atmasphere- Your point about non-sinusoid output waveform and generated secondary harmonics are well taken. However, Sola mitigated this by adding an additional “neutralizer” winding in the secondary. The following document contains a description of how it works. Refer to the PDF page 4 under the heading “Ferroresonant power conditioners and harmonics”. https://www.emerson.com/documents/automation/product-guide-solahd-power-conditioners-en-us-99748.pdf |
