I'm a composer, pianist, and audiophile, and if you would like to seek great quality with great value, I recommend the following professional near field monitoring systems:
1. More expensive, but great relative value for what you get (my current audio recording editing monitor system): Genelec 8341A monitors (larger models are 8351 and 8361); these can be -- but don't have to be -- combined with one or two related subwoofers (model 7350A or there are larger model options) -- I have two of these subwoofers that I purchased used. I output my piano recordings from my MacBook Pro via USB through a MUTEC MC-3+ USB master clock/reclocker; I've also purchased a new USB connection controller by Genelec for this system (model 9320A), but haven't received it yet. All of the cabling is by DH Labs (silversonic.com), which was very reasonable. What prompted me to investigate this system (including the MUTEC unit) were (a) Audio Science Review's Master Audio Review Index (these Genelec monitors were at the top of the rankings), and (b) a review on Sweetwater.com of the Genelec 8341A monitors, by an audiophile and pianist -- his comments were not only correct, but I went further and added the subwoofers, which substantially improved the system: "Not a pro, just an audiophile; incredible sound for the price. I'm not a sound engineer, just a software engineer and piano performance major with a long time love of audiophile systems that can reproduce natural, you-are-there sound. I bought these for my office workstation system, to provide "good enough" background playback of hi-rez streams from Qobuz and Tidal. I was flabbergasted to find that the 8341's driven by a bare bones Roon Macbook USB -> Mutec 3 front end could almost match the main listening system I've spent 15 years optimizing component by component at 20X the price point. Not to mention 10X the physical space requirement. FYI, I've tried plenty of 'bargain' hi-fi options as well over the years, from JBL to Paradigm to PSB to Focal and B&W mid level, so this isn't simply a case of a a stupid audiophile being unaware of what less expensive equipment with good base specs can do. There is some material, such as 60's through 80's classic rock that I actually prefer on these over the main system."
2. Much less expensive, but great (my prior audio editing monitors, which I still use for recreational listening): Dynaudio BM6A MKII active monitors (which should be readily available used, or you could get the current model); Dynaudio made (and perhaps continues to make) a subwoofer designed to supplement these.
P.S. I would also add, importantly, that having two source/headphone systems of similar total cost to the Genelec system, and after listening to vastly more expensive large systems, I think the best value audiophile solution -- if you want to optimize sound quality and listening alone -- are near-field monitors -- the audiophile sweet spot in driver size, in my opinion, because: (a) they minimize the room acoustic issues (since you sit close to them -- the drivers on my Genelec system are two feet from my ears) that are often costly major problems for large systems, while (b) providing large enough drivers to provide the physical acoustic bass/low mid-range that headphones can struggle to replicate because their drivers are necessarily small.
