Krell Evo vs Evo-enhance

Knghifi,
Game starts with the circuit box of the entire flat or house. IMO, the decisive factor is not the way how inwall lines installed, BUT, how the circuit box SUPPLIED by the MAİN line. If it is weak and designed for a standart citizen, than, problems begin.
In my case, I replaced entire network, all main lines to my flat, all the critical circuit breakers in entire residense, even short circuit breakers in my flat, and commonuse in residence.( neighbours didn't pay me anything)
Afterwards, I have decided not to depend on AC from company but logical way to re-generate for entire flat, re distubute the phase, re-organize the circuit breakers, internal lines.
I ended up with: 2 5kw in line voltage regulater-stabilizer(audiophile grade, custom made) one for setup, one for rest of the flat, Lapp Kabel ollflex cable for setup supply, 32a AHP Klang Modul circuit breaker for setup. (all circuit breakers and cables are Made in Germany)
(I would recommend Oyaide Tunami cable for internal lines but it will be costly and technicians may extra charge due it is very heavy and not easily bendable)
You may ask that does it worth? Yes it does, at least, psychological......

Mert,
We all have our own set of variables and priorities ... I'm SINCERELY impress with your efforts and I bet you are rewarded with great sound. Last year I replaced my outlets with Maestro outlets and could not believe the improvements so only could imagine your improvements.

I built my house ~10 years ago and was the GC (VERY BIG mistake). In hindsight, I should of spend more time designing the electrical for my sound system. Priorities priorities ... probably redo in the near future.

I UPGRADED FROM EVO 600 TO 600E, ALSO HAVE 400E AND 302E FOR HOME THEATER. I HAVE HAD MANY KRELL AMPS/PRODUCTS OVER THE YEARS. THE UPGRADE TO 'E' VERSION IS WORTJWHILE. THERE IS A MAJOR REDUCTION IN ELCTRICITY AND HEAT GENERATION IN STANDBY MODE. SOUND IMPROVEMENT IS SUBTLE. I UPGRADED FROM STEREO KRELL AMPS TO MONOBLOCKS SEVERAL YEARS AGO. I NOTICED AN IMMEDIATE, OBVIOUS, HUGE IMPROVEMENT WITH THE MONOBLOCKS IN EVERY RESPECT. BETTER INSTRUMENT SEPERATION, MUSIC EMERGES FROM BLACK SILENT BACKGROUND, BETTER BASS, FASTER, MORE MUSICAL, BETTER LOW LEVEL DETAIL, BETTER 3D SOUNDSTAGING. A-B COMPARISON WAS NOT NECESSARY, THE IMPROVEMENT WAS OBVIOUS. I WOULD UPGRADE TO THE 'E' VERSION AND WOULD ALSO USE MONOBLOCKS IF THEY ARE IN YOUR PRICE RANGE. BASED ON MY PAST EXPERIENCE WITH KRELL AMPS, I THINK GOING TO THE 'E' VERSION MONOBLOCKS FROM THE STEREO 'E' VERSION WILL PROVIDE A GREATER IMPROVEMENT THAN GOING FROM THE PRIOR GENERATION EVO TO THE EVO 'E' VERSION. ALL OF THESE PRODUCTS ARE ABSOLUTELY SUPERB. YOU REALLY NEED TO LISTEN TO THESE PRODUCTS TO DETERMINE FOR YOURSELF IF YOU CAN DETECT A DIFFERENCE AND THEN YOU CAN DECIDE IF THE IMPROVED PERFORMANCE IS WORTH THE ADDITIONAL MONEY. I LOVE MY KRELL AMPS AND KRELL EVO 707 PROCESSOR. THEY ARE BEAUTIFUL, BUILT LIKE TANKS AND PERFORM BEAUTIFULLY.

I have the 400 s , as far as i read its more about reducing standby power consumption
I would also add levinson amps ,400 serie for example which i had before also good stuff

I must say I am pretty sceptical about the green stand-by, which reportedly "consumes only 2W".

2W per hour is that minor, so only reasonable explanation might be that the green diode itself consumes the whole 2W. That means that during "green stand-by" all major power supply circuits are essentialy fully disconnected yet, out of current, so that a real warming-up of amp actually does not occur. Real warming-up, of course, occurs during so-called "high current stand by" (red diode), which consumes some normal 150-450W per hour, depending on Evo-e model. However, this normal red-diode-indicated stand-by is being already known from the original Evo (not "e") series.

What does it means? Well... Ask Krell's marketing department...

BTW, I am happy Evo-400 (not "e") owner. Would be perhaps a bit more happy if own a pair of new Evo-400e, not because of the green stand-by but because of other improvements (reportedly slightly upgraded power supply, increased filter capacity etc).
