The Evolution series amps put out gobs of current compared to the newer amps.
Nevertheless, I am very eager to hear one of the new amps in my system with the Foundation. And, I assume Stereophile will review one of the power amps relatively soon and JA will publish measurements, which will be interesting to see.

"If you are the owner of a new stereophonic system, this record will play with even more brilliant true-to-life fidelity. In short, you can purchase this record with no fear of its becoming obsolete in the future."

Taken from the Krell site ...
" The Vanguard’s amplifier incorporates a massive power supply with a 750 VA toroidal transformer and 80,000 microfarads of storage capacitance "
the s-550i " a massive 1,750 watt transformer and 68,000μF of capacitance "
the s-300i instead " Employing a massive 750 VA toroidal transformer and 38,000 microfarads of capacitance "
It seems that the Vanguard has a power supply similar to the s-300i
For what counts of course.
The s-550i is more than double the VA but also much more expensive i suppose.
Kind regards,

...again my old McCormack had some 130,000 microfarads of capacitance. Oh well, it's always the sound that counts!
Hi i do not want to deviate from the topic
Only to say that before i was obsessed with uFs in the power supply
Now instead i am obsessed with the transformers VA rating
And Krell is a champion on this
They have unbelievable quality transformers and i think it is one of their strong points
I love Krell amps in general
I think that the mains transformer is the first and most important bottleneck for power
For this i always look at the power consumption on the back
To stay in topic i am afraid that the toughest competitors for this new Krell are older Krell integrateds that can be found around at very interesting prices.
Kind regards,
bg
