I do not think you need anything in your current configuration.
If you use the only one sources and all the you need is to manage volume then
you can put an attenuator in your phonostage before the output stage, presuming
the phonostage has enough current to drive you 35’ cable. If you are looking to
get rid of the active crossover and go all the way passing, if you do not use
high order filter then you can do it but you would need a strong current source
in your phonostage’s output stage. If you phonostage has 100-200R and you have
the only 3 amps then you can make the amp to have let say >300kR input impedance
and you should be able to live with it. There is no need to create complexity and
to buy boxes if you do not need them. Talk to the guy who build your phonostage.
I do not know what it is. if it is SS then you can run it much harder with high
idle current, perhaps beefing the radiators and you can have much stronger
output. If it tube then you can use other tube in output stage. It is all deepens
what it is and how playable the phonostage topology is.Rerurn to Romy the Cat's Site
