Tube versus SS


Since I just installed some rather expensive NOS 6922 Telefunken tubes in my Phono-preamp, that yielded outstanding results, I decided to compare CD to Phono.

From the best of "Jacintha", CD, I selected "Danny Boy". Her voice emerged deep center stage from a jet black noise free back ground. It sounded more like what I expected from the analog.

That was followed by special LP's of Dinah Washington that had recently arrived. Those LP's were everything I expected with the NOS 6922 Telefunken Tubes in the Phono, but the surprise was the fact that I couldn't tell the two apart; both were outstanding.

What may surprise you, is the fact that I attribute these outstanding results from the COVID 19 "lock-down" which has given us the quietest "grid" ever in history. That means those of us with lesser means have the same AC power as the richest who can afford expensive AC power "clean uppers".

BTW, I have made extensive comparisons to recordings made before and after, the lock-down that confirm just how much of a difference it's made. I must admit that I had doubts about expensive power conditioners, but this confirms that fantastic results come from taming the wild AC.

It's my belief that we can not achieve better results than we have from the current "quiet grid", which means power conditioner or no power conditioner, we are all presently getting the same results.

Could it be that the dominant factor when comparing tube and SS when they both are of comparable quality is "The quality of the AC"?

How much is lowering the noise floor worth? That’s a subjective question that only you can answer for yourself.

I’m a big fan of “more info is better” aka “another data point” (echos of MikeL), so I suggest you can try a power conditioner for free from a retailer that allows returns. On Amazon, there are a few power conditioners $100 and less with good ratings - I haven’t checked anywhere else so there’s more out there. If you like what it does in your system, you can also buy used to save some dough or move up to a better model.

@mikelavigne,

If you don't need massive amounts of power to run your system would a  stand-alone box regenerator be enough?

Dear @mijostyn : "  For low level devices like phono amps battery power supplies are king. "

Not really, all depends of the quality of the circuits design and the designer knowledge(skills to design a good power supply for that unit.

Btw, I hope one day could be at your place. Thank's for that.

i think how you do this is to compare your stand alone box to the regular wall outlet A/B for a period of time and with different types of music.

first question; are the dynamics (especially micro dynamics and lively-ness) equal or better? 

second question; lower noise and improved refinement?

third question; harmonics, textures, timbre better or at least not diminished?

bottom line; how do you 'feel' about what you are hearing? has the stress left your neck and shoulders? are you wanting to listen longer than before?

if these answers are 'better' or at least as good then it's working.

Continuing with the 'seismic theme,' and the vibrations/resonances from human activity, here is data from the bands (and more) during the Rose Bowl Parade in Pasadena.
