Is it me? Will I ever be satisfied?

Ok the Bluesound is a decent digital transport as long as you use an external DAC. I recommend an “analog” sounding Lampizator Baltic 3 for that. You should also look into the Auralic Ares G1 or G2.1 streamer.

Those old transparent cables are sucking the life out of the system a bit. Try Shunyata delta or alpha level power cables (do not get the noise reduction connectors for the tube gear get the XC not NR…NR is for solid state and does weird things with tube gear I tried them with) and then for something accurate for speaker and interconnects an American company called Kubala Sosna you will find has more resolution but won’t emphasize treble or sound weird like other brands and I recommend Temptation level in the middle to start. That’s what I use in my YG Accoustics Carmel 2’s. Your B&W speaker has a more forward sound with the diamond tweeter and you need a cable that is accurate and won’t turn them into double treble murder canons. GTT Audio can help you with the cables and maybe upgrading the streamer to the next level with an Auralic Ares. Fred can help you over at Lampizator North America since they sell direct. Sources are all neglected it’s not just the amps. That old Linn is cool but a better turntable is a Kronos Sparta 1.0 that has a counter rotating plater underneath the main plater to counteract all vibration but turntable last.

Amps to look into are Belles Audio….Think Pass Labs and McIntosh with more resolution but better value. Audio Connection in NJ can help with them and they will  go perfect with your new preamp. You just need a Belles virtuoso stereo amp. 
If you can swing it try Mola Mola Kalugas they are class D and pair great with tubes and the treble is sweet and slightly rolled off to curtail the diamonds. I am 40 so I tried a lot of new tech most people refuse to try. The Mola Mola needs to be plugged in a whole day before they are ready to do critical listening. 

You know what helped me…? Listening to sound systems in my local shops. There are three places not too far from me and they each have a different approach and different gear. I listen to mine, and then I listen to the $280,000 system at the dealer and I don’t feel too bad…! Mine sounds close…but I can hear the room for improvement. Not having an unlimited budget makes each step exciting and semi torturous…

Nothing a few weeks in therapy might Cure. I’m having a blast. Hope you are too.

Fix the room 1st. Treatments? Using the rule of 1/3’s, 1/5 for speaker placement. You don’t need equilateral setup, if you read Jim Smith’s book/video, he uses 85% (?) distance between the speakers to how far you are away from them. Also, you probably don’t want those tweeters beaming straight at you, try forward facing with little toe in, Then get a McIntosh or Classe amp to tone down the sizzling B&W speakers. Every dealer I saw with B&W speakers always used these amps for good reason, remember B&W bought Classe years ago which were warm sounding amps. You have a weak digital setup compared to your other audio components. Get a good external dac with Ethernet and/or i2s, there are many from $5k up, move the bluesound to a bedroom or an area used for background music and use a computer with roon or get an Auralic Aries/gx or nucleus if you don’t want to deal with computers. If you cartridge is old, get a new 1 or get yours rebuilt. 

Quick answer: NO.  You have an addiction , a fever, and you will never be satisfied until and if the fever/addiction tempers and washes through you.  Eventually you'll get over missing the arrival of the new toy and the hearing the new sound, maybe.  If you have the cash now, you may really be in for the long hall though because the temptation spend money is strong.  But just in case you want to drop another $6,000, get a Holo Audio May KTE to feed from your Bluesound Node.  I did that with my C2700, MC611s and Legacy Focus SEs, huge sound improvement.  I feel like my fever is starting to ebb.  Maybe.

@goducks44 , can you ever be satisfied? Yes, absolutely. The problem is that you have to know what you like and how to get there without spinning your wheels.

If you are unhappy with the sound of your system it is far more than likely that you are unhappy with your speakers and room. While electronics particularly amplifiers do make a difference they are at best 10% of the show. 

Before you spend more money you need to find all the dealers near you and listen to as many speakers as you can. Shows will be starting up again. Do your research and take your time. Good speakers will last you a life time. Do not shy away from listening to very expensive systems. You have to have points of reference. Listen to all types of speakers, horns and planars. point source and line source. If you have any small clubs near you go listen to live music, another point of reference. 

Once you have the right speakers you have to deal with the room in the context of those loudspeakers. If you want to be scientific about it get one of these so you can see what you have to do and measure the results.
