There is no reason to put the extra choke on there. Chokes are supposed to be designed specifically for devices they are used on. The inductance of that extra choke could affect the freq response. I'd remove it. Not that it will necessarily help, but the original chokes are still stuck...

That's not them. They are ~1/4 thick doughnut shaped ceramic magnets. The wires are wrapped around each one several times. Maybe just separate them as I said, but it might not make any difference. They may just be there to pass a computing device inspection. My PC noise overpowers the...

I hear you on that Tim. Not sure it's worth the fuss, but you might try moving over one of the speaker wire chokes just in case it has an affect. It may even reduce the hiss. I don't know. Just need a way to tie it to the ground wire. I had some extra wire ties. I keep the volume at 7 anyway...

Thanks for doing that Tim. Aiken Amplification recommends polypropylene film caps for best temp stability and clarity, so I might use those if I can find the right values. If I knew which were the input coupling caps, I might just change them. The 100uF caps I can find of these types are very...

Hi all, and thanks to Germanium for posting all this useful info. I just got a pair of LSR305 myself, and I find the caps mod intriguing. I am also considering filling the baffle and possibly coating the rear plate and port with something like Titebond 'Fast Set Polyurethane Construction...
