Mark, I guess the "little guy" isn't so little at this point anymore, then. I'm sure he's getting a great home, though, either way. I hope he's settled in fairly well by now - it always takes a few days.
Guys, just a bit of an update. I've now modded my VIM to some extent. I added 1 47uf oscon, 1 0.01uf polyester and 1 150pf mica cap (in addition to the original 0.1s) to each voltage rail of the first 3 amps and the multipliers on my 03 board (removed the stock 1ufs here), and added 1 22uf tant as well as the smaller caps on the second set of amps due to space contraints. I have also subbed in 0.47uf stacked film caps like the type Bill is using for the input caps.
Since my projector still isn't really set up well, I gave this modded VIM and my set of neck boards (G2 resistors swapped for metal oxide, coupling resistors for signal path swapped out for metal film, 2x 1uf Z5Us swapped for X7R, blue 22uf caps subbed for 100uf caps, some additional capacitance added to the +-5volt rails near the amp, although not as much right now as on the VIM) to Paul Bellemare (GN2) for testing on his 8000.
Although it was somewhat of a quick test, Paul watched a bit of HD, and also used his computer (9700, not MPd) for a bit of veiwing.
He was not too inpressed with the changes so far, although he noted that the scanlines were maybe a bit more distinct, and there was a small bit of added detail to the background in some of the HD he viewed.
Therefore, as it stands, the changes are reportedly somewhat negligible, and probably orginate primarily from the input cap changes, and the resistor changes. The extra decoupling on the VIM does not appear to significantly help out the image when using the stock clc449s, as Mike and Bill both alluded to earlier.
My plan is to swap out the clc449s for the EL5166s that we talked about earlier. These are specced at roughly the same values for feedback as the clc449s are using on the board, and have a MUCH higher slew rate, and (maybe) has a higher bandwidth. I say maybe because the specced gain of 2 bandwidth on these ( http://www.intersil.com/data/fn/fn7365.pdf
) is not clarified for what output voltage value is being output. The clc449s have a typical value of 500Mhz bandwidth at gain of 2, large signal output. The 5166s give only that they have an 800mhz bandwidth at gain of 2. As stated, they still have a VERY high slew rate, so maybe the difference between large and small signal is much smaller due to the possibility of a much steeper slope for the edge of a square wave. I don't know, but I will see if they make a reasonable direct substitute in the next few days.
EDIT: I just took another look at the datasheet, and found a graph on page 6 of the 5166 datasheet regarding large signal, gain of 2 bandwidth. At gain of 2, 3v p-p input (therefore 6 volt p-p output), the amp has a very respectable 350mhz -3db bandwidth. Therefore, at a full 6 volt output, the bandwidth is a little under 50% of the smaller signal bandwidth. This is pretty good, as the CLC449s have a typical 500Mhz at less than 2 volt output (maybe input, but this would still only give a 4volt output). Note that the min according to the clc449 datasheet at 25 celcius is at 380mhz for this statistic.
