So my:Freq. Range -6dB at 52Hz and 30kHz Sensitivity 88dB spl (2.83V 1m) Normal Impedance 8 ohms (minimum 4.3 ohms) Power Handling 25W - 100W into 8 ohms on unclipped programme B&W DM303 aren't ideel :/
Even when the stock volume is at its max, the signal still passes through it (degradation), and it is adding 50k of load to the source,
Hi Vinnie, I feel that your statement needs a bit clarification. Even though the signal does pass through the stock volume control even when it is at its max, that 50K resistance is in parallel with the signal input of the Tripath chip. In other words, the volume pot in the maximum position does not impose a seriesl resistance before the chip input. You get the 50K of the volume pot in series with the chip input only when the volume setting is at 0.
Coulnd't you just put a better pot in there??
If I use a 14V battery, could that help?
Chair Guy: Great! I gave the SLA battery a full charge overnight (it was originally 12.1 v.) and notice even more of what I heard yesterday: better bass and dynamics. What prompted me to try a lower setting on the SI's volume control was the THD plot I saw somewhere, with very bad things happening above ~5 watts. Seems to work.Regards,Larry Welsh
Have fun! Vinnie

Quote from: Vinnie R....I am actually staying away from a preamp, as I find that this modded little beast sounds the best without it. ..Vinnie,What mods have you done on the SI? I reread the thread and only found the SLA battery mod and metal chassis mod. Have you changed out any components on the board itself?Thanks.Todd
