Will this amp trick work for increasing bass performance?

@gdaddy1 Did you say "connect them [subwoofers] directly from the speakers". Can you elaborate on the exact wiring in this scenario?

I play Tidal via Chromecast to my streamer, wirelessly. I also have a AudioQuest Dragon Cobalt that I attach to my iPhone or MacBook, then via a 3.5mm to RCA to the pre-amp.

I got suggested that Roon can play the Tidal library too, which superior results

Robert,

I just positioned Two xa60.8's in my listening room. They are paired with Paradigm Personal 7F's and a Premaluna Preamp (EVO 400), streaming Qobuz on Lumin. I am literally 30 hours into burn in. Our specs are not exact, but similar. You're getting a lot of great advice from some qualified folks. To fill my knowledge  gaps, l called Pass and spoke to Kent ( long term technical support), he was excellent to work with. I was looking at all the same amps and he astutely guided me to the 60's. I purchased the from Reno HiFi. Mark is the owner and excellent to work with. I wont speak for him, or the options he will positioned, but I was very confident he would work with me until I had the amp/s I wanted. The bass generated is significant tight and very detailed. I have two subs from the previous configuration that are unlikely participants in the new line up. This is not an advertisement for either, my first exposure to both, just an excellent experience I want to advocate.

@mkdm11 Thanks for sharing, are you bi-amping the XA60.8? Please elaborate on how/to what you connected each power amp

Yes, provided you have 'high level input' connection on your subs. Most higher quality subs have two ways you can connect. Either 'low level' RCA connection from your pre-amp (passive) OR you can run a short set of wire directly from the back of your speaker connection to the 'high level' input on the sub woofer. 

Super easy to do provided you have 'high level' inputs.

The reason I ask about Tidal is that some people connect from the TV app. This method gives you low resolution and very reduced dynamics.
Your connection seems to be fine.

Don't know the best way to connect an equalizer to the Ayre.  Address the question to the manufacturer.
