I'm so not judging.  I purchased a $2300 ADC just to digitize LPs. 🙂

I'm using a KORG, thinking of upgrading. What'd you get?

Put them on top of your source/amp components - an easy way to get rid of undesired vibrations!

Now I'm imagining working out the locations they can safely sit without putting too much load on the floor and underlying structures. Getting them into position one will of course have to follow carefully planned paths, possibly coordinating their movements to avoid temporarily exceeding any limits. Kind of like those old Sokoban games.

@mitchco will have to redo the DSP algorithm to account for all the gravity wells.

Is it that cold in Minn-e-sota that you have to resort to such inefficient heaters?  Or did you bury 6 gauge cable under you sidewalk and will hook these up to melt the snow and ice?

I'm more concerned the smaller one is going to be end up being dedicated to A/C starting the end of next month based off the +40 F too warm Winter.

Sorry to go off topic here, but you've made a dangerous mistake. Let's assume the average January temperature in Minnesota is 24 degrees F, but this year it was 32 degrees F. Someone has taken the values, converted them to centigrade, and reported the difference in centigrade. 24F = -4.4 C and 32F = 0C. The difference is 4.4 degrees C, which you've now converted to 40 degrees F. But the temperature wasn't 40 degrees F warmer than normal, because your average temperature in January wasn't 64F. Time to abandon that Fahrenheit stuff.

Fahrenheit was the scientist. The temperature scale is Fahrenheit's monster.

A dangerous mistake, eh?  Allow me to explain what a dangerous mistake in MN during Winter is.

 

a)  Pulling out the tropical board shorts and flip flops to go shopping in before the first week of below zero Fahrenheit temps have set in.

 

b)  Opening your mouth to make a prescient point about anything in -50F - -80F windchill on any number of days a slight grey cast barely rises to signal daylight.

 

 

I'm not even close to joking about using his A/C by the end of next month.

Now that is thinking like a true Minnestoa'ian! Yaaaa

Look forward to hearing how these transformers affect your SQ, as most Audiophiles know, power supply, especially to digital sources, is key! 

I wouldn't necessarily agree with that, but we can agree to disagree. 

 

I think any well engineered product should have proper isolation, grounding and voltage regulation.  These are all known things, particularly with the filter designs once you get past a stepdown and rectifier stage.  I've always been intrigued with the lengths that people will go to for "pure power".  Living in the forest with power supplies that aren't so reliable I placed more value on power protection than anything else.

 

I look forward to a review from Chris on his latest change.

Nice! A heavy transformer is often a great transformer. I eagerly await what the "100% proprietary design" is  

[Ralf11]

the special twist in the power cord?

[plissken]

Yay balanced power.

[Crom]

ooh, exciting. I bought a second hand one of these last year - soundstange, bass, cohesion...all improved. A great upgrade in my book!

[Ralf11]

bass cohesion or bass and cohesion - if the latter, what is cohesion?

[Crom]

The immediate thing I noticed once I'd plugged it in (very heavy lifting alone!!!!) was that the bass improved. Fuller...there was just more of it but not in a bloated way. It was punchier too. Better bass transients in a system that I already rated as pretty responsive. Then there was better texture across the board. acoustic instruments just sounded more...acoustic. The cohesion comment came from how the instruments hung in space better. I place great importance in the soundstage on my system and this definitely improved it. Not really the scale of it, but the fact that it was all a little more differentiated. I can quite honestly say that this was my favourite upgrade of last year (etherregen comes second).

[The Computer Audiophile]

Oh wow, I like these balanced power units. Got them connected this afternoon. Fantastic.

Quite typical of the sort of gains when the delivery of mains power to components is improved - most gear has power supply sections which are not engineered well enough, and everything you do to give this area a helping hand will benefit the subjective SQ. Impact of the bass line is often an obvious gain ... it just has more "guts" to it, 😉.

they (usually) center tap the 120-Volt output  

 

 

Is that what you mean?
