Best Bang for the Buck Upgrade

Room Treatments.

Hello,

Whatever you can get a better deal on used out of a DAC or an integrated. I would replace the DAC first especially since you are using a transport. You have really great speakers. When you replace the DAC with something of that caliber and price you will be amazed. The biggest reason people hear such a big sonic change when they upgrade the integrated is because of the preamp section in the integrated. This is why I prefer separates. You buy an amp that is good enough to push the speakers well. As you upgrade the preamp you get a really jump in sound. Plus, if you are running all digital you can run a killer DAC on a good amp especially because these DAC/streaming companies have figured out to adjust the volume from the chip and get great results. I still prefer a preamp with analog inputs even if I am running all digital setup. I run a nice vinyl system so I need analog system. That’s why I like the Lumin P1. It’s a preamp/ DAC Streamer. I just listened to this awesome piece of gear on a 20 year old amp pushing KEF blades. Pure harmony. 
I also love the sound of the Ayre QX-5 DAC with the Network/ streamer option. 
Another reason I prefer separates is you can upgrade individual pieces of gear and if one thing has become obsolete like a DAC you can replace it. I do know that some companies like MAC and NAD have cards to make them semi future proof. 

Fix your sub and add 1-3 more of the same sub.  Add room treatments.  Get a dedicated power line.  Add a streamer.  Go to dinner and drinks and then to some live music events.  Take dance lessons.  Stay overnight somewhere an hour or two from home.

Yeah would be pretty pricey to add more JL subs! I think they are like 4K a piece for the F113 now. Don’t think I can get away with more subs with the wife. Maybe 1 more. 🤔
 

Thanks guys lots of stuff to consider. 

A user above mentions "silver link RCA for a startling uplift in information transmission. " Can anyone confirm this? Silver RCA plugs and sockets making a big diff??
