Help looking for dynamic warm romantic sound with detail

First of all, I do not think you need tubes to get what you are looking for. I agree with some of the other comments... B&W CM10 probably won't fit the bill for what you are looking at. Throw as much of your money as you can at your speakers and upgrade the amp section later if need be. The warmest speaker I can think of would be anything by Harbeth (SHL5+ for dynamics amongst the Harbeth line up). They will have some detail as well but not insane amounts. I find the new Kef R series and the Kef reference (at the upper end of the budget) to have good detail but are not bright. They also put out a crazy soundstage. Maybe check them out if you get a chance. As well, have a look at your source (PC). Laptops, PC's, Mac's, etc are some of the worst possible sources for digital. Even a cheap dedicated streamer like a Bluesound Node 2i should provide much better performance than a noisy PC. If you intend to stick with a PC for your entire journey have a look at some products like the audioquest jitterbug or the ifi isilencer products. These things will help reduce some of the noise over your USB. 

Everything in your system will play a part in achieving your goal of a dynamic warm romantic sound with detail that you seek.  
Do you have any local , or not so local audio dealers you can visit to listen to speakers and associated gear?

You could start off by researching speakers and amps that have the characteristics you seek and make a list. Go out and visit audio dealers that have these speakers and amps to listen for yourself. 

Do you have any friends that are into audio where you could go and listen to what they have? You could also check for local audio clubs/groups for learning and listening to other people's set up.

I would take your time and measure as many times as you need before you cut.

It sounds as though OP really wants vinyl going thru tubes. That's the sound I'm hearing him describe. Can't see how digital will get there. 

It’s without question,  we all have our own perspectives towards gear and will engage in technical banter, data points and all things from here to the moon.  But one thing I’m almost certain all will agree upon, room treatment and how it impacts sound.  A little will go a long, long way.  Some of what you’re hearing would be cleaned up with room treatment.  It could be the detail you’re seeking is being obscured by your room dimensions, or the positioning of your speakers, or a number of unrelated equipment items.  Either way, with a budget like that, you’d be doing a disservice to the gear by not optimizing their environment.  

Agree, look at your room first. Your budget is ample. I used to think B&W were the gold standard but there is so much out there. Can you attend any of the big shows?. This will allow you to listen to so many different setups in a short amount of time.  I also suggest bringing cash and buying the best system you can afford. The dealers are usually open to selling so they don't have to ship back home. That's what I did down to the cables. Very happy.
