Help in putting together my system with used equipment on Audiogon and eBay.

5+++++ for millercarbn first advice, go for good integrated. Accuphase is in my mind it is warm easy to use very good build, you can upgrade to good sounding phono stage and good quality dac . You saving money on cables which is tricky part too . And if you like B&W don’t go cheap the cheap sound cheap....... good luck!!!!!!

I believe that a given system has a voice, tone, and emotion. 

For me, I love the sound of a cello, piano accents, a guitars.  For the music flows over me is the big win. Its my personal pleasure.

After you figure out the size and presence speakers and your system can have in your room. Listen to whatever systems you can and find the sound that speaks to you. My opinion is the speakers have the most to do with that voice. Then find the top level of that brand speaker that fits you and start there.

The speakers needs will drive what amp you should have. 

Vinyl is an expensive and if don't have a passion for it, put it on hold and go CD or stream.

Focus on Dac next. Go for a new or newish dac, preferably that can be take software updates. A basic blue ray player used as a transport will save you money. Just use it as a transport . Or stream directly to the dac

Start with the factory power cords, and most basic interconnects. Tweeks are fine turning and will not know where you want to stear your system till you live with it awhile.

Yes great gear, monoblocks, etc are awesome.  But even used to get full value of amps like Pass labs, T+A, BHK, etc. Your budget isn't gonna get you there.

But you can build to it if that what you want.

B+W, not my favorites. I find then fatiguing and too technical. That sound is theirs across the line. I bought a pair new, and wanted to like them, just never got there. Haven't even hooked them up after moving 4 years ok

Here’s a YouTube review of the Klipsch Cornwall IV if you haven’t seen it.

 Steve G. also reviews a few other speakers you might be interested in his other reviews.

I haven’t heard your specific equipment but many of the other components described in a “Audio Show” environment. So much depends on system synergy too, so it would be hard for me to comment on the sound using your components. 
I would also recommend the Florida show to help you get some bearing on the type of speaker sound you like. Always let your ears, not specs or opinions be the judge (if at all possible).

Good luck in your journey.

I've had a LOT of recommendations on tubes. I don't even know there was a tube PRE amp. How does a preamp make a difference in the sound? I thought it was just a unit to plug all the sources into. Man do I have a lot to learn. I want to than you all for the posts, I have learned a LOT from you all. I know it will be my personal taste in the synergy of the system I put together, that tubes, if I decide to implement them, will add to the synergy. A few have said the Class A/AB Pass XA30.5 amp would go well with my system. If I decide to hang on to my Klipsch Heresy III's, I will have to give them a listen or hopefully hear the difference from an audio store. I really need to figure out the digital side of my system, I am totally confused on that. I don't need a unit that streams wireless or an amp, but they all seem to do that. So a good DAC and cd ripper is what I'm after. I appreciate your posts! Please keep them coming, I learn a little from them all, and I still have a lot to lean. Thanks everyone. Especially Mrdecibel who recommended I take it slow and just buy a cd player for now. I had been listening to the tuner on my Yamaha 5250 for so long I thought that was as good as my system got, and then a clean signal from a cd went through them and DAMN! A newfound respect! If it gets a lot better from here, I am hooked!

Skip the phono.  It costs too much for the rewards.  Don't buy a crappy system and waste your money tweaking the hell out of it.  For your budget, it would be hard to beat old B&W 802's, either Series II or III, preferably the latter.  The Bryston amp is wonderful.  I slightly prefer my Audire over my Bryston, but Audire is extrinct, and you are looking at an ST version, redesigned by Stuart Taylor.  He did a lot for several companies, including the Adcom 555, which if put to the specs he actually designed, before the accountants neutered it, was great.
Get a good preamp.  I would recommend an Audire, but not anything you will ever see, because the much praised Legato is a bit weak in the power supply, and does not have the impact of the Diffet 3 or 5 or the Andante. The two is pretty good, but also rare.  I have had most of these and settled on two 3's, after I missed an Andante.  Try to find a really good CD player and tuner.  Go to fmtunerinfo.com to learn about these.  I tried many over the years, and their listening tests are spot on.  I would suggest that a Sansui TU707/717 as a minimum for both listening and playing with.  If you want to just set some stations and listen, the B&K  TS107.  It sounds so good that I have to use my Audire Diffet 3 to tell that it sounds different from my Monster Kenwood KT-917 I bought in 1979.   My Diffet 2 does not bring out the difference.  Sadly, the B&K is better than the 17 in the lower bass, but only on a really good recording.  If you decide to go for a TT, I do have one to sell, as well as a couple of extra arms, but I recommend you save your money for the rest of the system. Unfortunately,  i am a bit ignorant on current pre-amps that are within you budget, But I would get a Bryston to match your amp. $1700 amp;  $800 preamp;  $400 tuner;  $!500 B&W's;  and you have money for a good CD player and, if you wish, a streamer.
