OK, you got a Lyngdorf processor and PS Audio amps, the toobs are high maintenance and nickel and diming you on replacements.
Lyngdorf amps are of the two channel variety (SDA-2400) and at $2400 that works out to $1200 a channel. Your atmos rig has 11 channels so is it worth $1200 x 11 channels= $13,000+ to add 6 of those amps to your stack and hit the bid on the toobs?
If you miss your toobs get a tube based headphone amp. This one has a preamp out so you could use it as a 2 ch preamp as well.
You could hook the RCA out from the Manley to the RCA in of the SDA 2400 and the XLR out of your processor to the XLR in of the SDA 2400. You can switch between the inputs on the back and that amp would be driving your Paradigm 9H's.
