My next project was in building an over the top (bordering silly) big P/S to run a Hafler 500/600 modeled amp and eventually use the Exicon T0-264 dual die MOSFETS or possibly 2 pairs per chassis, of Hypex UCD 400/700 or ICE500/1000a power modules to build mono blocks for bi-amping my Maggies. A whole other post and topic [later this year]
I chose this layout the amps differently due to using a larger 1000va toroid and the huge United Chemi Con electrolytics. This supply will drive the "Hafler 500 or 600" with great reserve and will easily have dual amplifier modules per chassis. At this point I still consider these proof of concept builds... as I am experimenting with parts and wiring layout. I have listened to the 500 heatsink with Musical Concepts PA7 driver boards for about 3 weeks and am very happy with results, it is amazing. *I chose these large 39,000 mfd caps, in that *IF* I did not like the result, I could repurpose them in a "stock chassis" of a 500 or 600 amp...
In the meantime, while I re-built the chassis pan of my XL600, using Cardas RCAs and 5 way binding posts, along with heavier gauge wiring, cleaned up the AC wiring layout and installed an IEC jack. I stripped the amp down exactly like the 500 to keep everything the same... for easy comparison. Right now the XL600 is powered by the Franken'Amp CLC supplies... I have only taken a few pictures... too busy listening. This 3 piece Franken' amp is a monster, frankly I am nearly surprised I have not popped fuses in the Maggies, not by abuse or clipping... simply putting humongous amounts of power into them. I never heard any Maggies or my Maggies play like this... I doubt the I would ever need a subwoofer... they do ~ big ~ tight ~ bass. This amp configuration exerts incredible bass control over the panels...
I needed to create room for the audio circuit (in the back 1/3 of the amps) and will admit to feeling driven to isolate the magnetics of the toroid and inductors from the audio circuitry... I pondered the parts in various layouts for over a month and finally resolved all of my goals with this layout. I wanted to keep the wiring paths short, symmetrical and tidy [rats nests make me crazy] not judging anyone else's work, I am my own worst critic.
This power supply driving "Hafler 500 and 600" has ridiculous clarity, sense of finesse and effortless ease. The Macro and micro dynamics are unparalleled, compared to any amp that I have built in 40 years...
My reference for sound has been the Futterman OTL4 sitting in the middle of the frame... I have only powered it up ~once~ the past 2 months of being blown away by the CLC designs.
