Jeff Rowland 625 amp ... & 725

Inna

5 countries in Europe are still rated triple AAA by S&P
USA has already been downgraded

and look at the devaluation of the $ in foreign currency terms
1970 1$ = 5 SF
1980 1$ = 3,5 SF
1990 1$ = 2,5 SF
2000 1$ = 1,8 SF
2010 1$ = 1,1 SF

today 1$ = 0,95 SF after bouncing at 0,75 SF !!!

it seems to me that the western side of the pond has some problems too

these are facts

Sure, I agree. It's quite a mess here too. Dollar is now a "political currency", its real value is quite low. But euro's value is zero, no value at all. Unlike Swiss Franc.

CES présentation of the 725 ... but also of something new ?

the PSU power storage unit

what is it exactly ?

Clavil,

I still have my Sonus Faber Concerto Domus hooked up.
I need to rearrange my listening room for more space around my Apogee Stages...

Check out this site for the Rowland gear:

Claude, I believe that the new PSU Power Unit may be an external supercapacitor-based power supply that can be applied to deliver DC to Corus, Aeris, and the upcoming Criterion replacement. I do not have any details from JRDG, but knowing a little about supercapacitors, it is likely that PSU may yield a great deal of transient authority to applicable devices.

And just in case you were asking.... No, you can't apply PSU to any power amps.... Just not enough current for that.
