Can I ask what is meant by "the GAT is still relatively new "? How many hours has the GAT2 been playing until now? Sorry if you already told, but what was the phono stage when using the GAT2?

It probably has about 500 hours on it, but it's still 'new' to me in the sense that I haven't fully explored it.

My phono stage is a CH P1.

Dimming the lights often adds noise to the power line. I never dim the lights. I turn them off or use low wattage bulbs. I do not think Ian uses his dimmer either, though I am not certain. The photos were taken during the daytime and the lights added a weird yellow tint to the photos, so I think Ron turned the lights off for the photos. Dimmed lights are not good, IMO.

Yep, can confirm dimmers suck.

Sorry, but I think this is exhibit z of audiophile nerviosa

Keith, I suggest you take it up with Brad. You are both more technology oriented than I am. I hear more noise with certain dimmers. That's all. Should I have written YMMV?

 

[bazelio]

Not an audiophile product in the video. I believe most dimmers are just high frequency switchers. So it's not really a surprise to see high frequency noise injected into the line...

 

[microstrip]

Yep, can confirm dimmers suck.

Unfortunately you can say the same about many modern high efficiency lamps. The now almost banned filament lamps were noiseless ...

 

[morricab]

Which is why I shut off my dimmered overhead light and turn on a filament reading lamp when I listen at night.


I found that the light on the dimmer damages soundstage depth in particular and I am not the only one to hear it at my place.

This is a whole new category of problem, requiring comprehensive EMI testing and evaluation of a wide variety of dimmer topologies to determine which produces the least noise. We also need to map the frequency range of the offending dimmers. There could be intermodulation distortion as well, when the dimmer noise mixes with our audio signals, visiting upon our systems yet more sonic havoc.

Clearly this is a serious problem in need of a serious and comprehensive solution.

I recommend that all non-filament illumination devices be replaced with candles. And not just any candles: candles made with the proprietary and patent-pending TrickyWick which absorbs and removes from our listening rooms not only dimmer-generated EMI but distortion-producing fractal energy as well.

Just buy the filter and you're saved!

Lighting on the same circuit as audio gear?

Great idea Ron! I nominate you as the Grand Poobah of dimmer investigations and retro lighting technologies! .

You will have full inquisition powers as you visit audiophiles and probe this vexing problem!

Mine is not but it impacts all the same.

Brad, probing audiophiles is pretty dangerous territory... I’m sure Ron might not see this as advisable nor even a very sanitary thing to be tasked with... let alone being appointed and anointed an exalted poobah of dimming.

I only nominated...perhaps you want to second it?

Lights are only for SS users.
Tube guys use candles.
SET guys dont need an artificial light soure. Their tubes are bright enough

Lol.

And SETs guys think that SS guys are dim bulbs

I think the TrickyWick needs a TAS review

It is funny that we have had this problem for decades - anyone has many of switch supplies around his system - but as no one has seriously studied the effects of mains noise in high-end equipment (this means qualify and quantify the effect) - probably your wicks will be a success. Remember you should have different types for tube, solid state and hybrid electronics.

Lol.

Ked what are you doing here now ? Should you not be out investigating all that Bangkok has to offer ?
Alternative use of candles and all !
