??? Which Would You Buy ???

Not an easy question to answer in a vacuum, but the premise of your question seems to be that you have heard these hypothetical components and to your ears you have the budget to buy one that sounds better and is built better than the cheaper one. Since you have the budget, I'd go for the better built, better sounding gear. You are going to be better satisfied and more likely to keep it in your system. 

For me, this would be particularly true if you're talking about speakers. I think speakers make the most difference and the range of performance across speakers is greater than than with electronics, to my ears. So, I'd  get the speakers that most suit you for the money you have to spend.  

 I’m not very prone to accept compromise in sound quality. I would look for other options at the lower price with 100% of the desired performance.  

Go listen to the components. Most often, with questions like these, the OP has made up their mind which option they want to go with and are posting the question to get confirmation. To be honest, I don’t spend $7500 on any component that others picked out for me. It’s completely my decision and I will be listening to the components not Audiogon members. Only I know how important budget will be, only I know how important sound quality will be, only I will know how important build quality and customer service will be, only I know how much time and effort I should give to evaluate a component before I buy it. 

I’m the last guy who should be commenting, but at 62, after a divorce, for the first time in my life, I put together a half-decent stereo system, that is decidedly mid-level. I did a lot of research and had a friend whose preamp or turntable probably cost twice what I have in my entire system. Do your research, listen to different things and decide if you’re going to be happy at 85% for a third of the cost. And by the way, I found lurking in and reading in the forum was extraordinarily helpful. I found my turntable and speakers in the Audiogon marketplace and the transactions were seamless. My integrated amp was found on eBay, open box, shipped from Germany at 2/3s of new. Also found the CD player I wanted on eBay, but hunted down the retailers and purchased directly. Spent 50% more than first anticipated (not including cables, but that’s for another day) and could not be happier. If you like the less expensive option, you’ll probably be fine. 

The question I would ask myself is spending 3 times as much worth a 15% improvement in sound quality?  
For me I have never been satisfied with the cheap route.  Being an audiophile is all about chasing that 15%, which is significant.  I always go all in.
