I named her "MAHGER". If anyone knows how to go about getting a metal badge made........?
The down and dirty:
-The amp chassis is made of aromatic cedar.
-4 LM4780 chips each wired in parallel.
-2 Noble (32 step) Pots. One controls the ESL's (highs). One controls the Woofers.
-2 420 VA torroids that are stacked and 1 12V transformer.
-4 Nichicon Super Through caps 10,000uf.
-4 Nichicon Gold Tune caps 4,700uf.
-Audioquest copperhead interconnect wire throughout.
The purpose of this amp is to power my Martin Logan Ascent i speakers in stereo mode. Essentially, this amp was disigned to bi-amp them. The 10,000uf channels push the woofers, while the 4,700uf channels push the electrostatic panels.
I know that I will probably receive some criticism for buying expensive interconnects and then cutting them up, but there really is a difference in sound (I did a side by side comparison). Will I ever do it again? ABSOLUTELY NOT, unless it is to build for someone else. I spent about $400 on just the green wire (audioquest copperhead) you see in the pics, but there really is a difference in sound from my last LM4780 amp. I just think that it is getting into the "law of diminishing returns". None the less, I felt that I would try to run the exact same wire from the signal source to the speaker output. The difference can be described as the amp has taken a deep breath. The amp is more open, although not in an airy sense. Transients are lighter, but clearer.
I am very happy with this amp and it was an "all out" approach that I took in building it. A once in a lifetime thing although I will keep building.
Although this amp was originally designed for the Ascent i's, it is capable of driving much more than that. Each component (ESL/Woofer) in each speaker has 120 watts available to it. Thats 240 watts per speaker in reserve. 480 total watts for the amp. But more important is the 840 VA that the power supply is capable of. Anyway, tell me what you think either way.
