Re: My 2024 Polk SDA 2b Modification Progress Thread (Drop1)
I suggest replacing the poly with a 0.5 ohm resistor instead of jumping it. That half ohm difference is very audible.

Re: How to connect two power amps to a single pre amp to run the power amps as two mono blocks?
This concept of how to invert the polarity of a single ended signal has been running in the back of my mind and I believe I've come up with a possible solution. One idea would be to use something like this:
Basically it would take a single ended input (in this example it is a 1/4" plug, so you would need an adapter to go from RCA to 1/4" plug. Then into the box and select the "inverse" (found on the other side of the box, trust me) button. Then use an XLR to RCA cable for the rest of the connection.
Whenever the "bridging" feature is part of the amplifier's design this happens in one of the interstage parts of the circuit. Most probably between the driver and output stages. This is more of a thought experiment, rather than something anybody needs to do.

Re: Bi-WIring Polk L800s for SDA
I forgot to address this.
The difference between a damping factor of 50 and 1000 is so tiny that it is laughable. In addition, to obtain a high damping factor generally requires a large amount of negative feedback, which may or may not be a bad thing.
I considered using the A21+ for the woofers because it has a damping factor around 1000, which suggests I could achieve tighter and more controlled bass, even at lower volume levels.

Re: Bi-WIring Polk L800s for SDA
Should I use the Marantz PM-KI Ruby and the A21+ for bi-wiring?
You are asking about bi-amping, not bi-wiring. Regardless, the answer is no.
BTW, the Ruby (excellent) is an integrated amp while the A21+ is a power amp only. Sell the A21+.
