Turntables.....A point of diminishing returns?


   This post is sure to elicit many opinions. Everyone knows that a good audio system is a series of building blocks. Amps, speakers, cables, etc. To find the weakest block in any system can be a challenge to make a particular system sound as good as possible given the funds on hand. Almost anything can be improved upon. But, where does it end? There seems to be a point that an audio system, thru improvements, is about as good as it will sound. At least to the owner.
   No end to opinions about analog sound. Tables, carts, cables, amps, setup, and others. With all the renewed interest in vinyl, many are looking to optimize their current setup and others are content with what they have. Congrats to those. Other than looking at this as just a hobby, at what point does one just say...that's all my system is capable?
   I say this because in the audio world there is almost no limit as to how much money can be spent on equipment. If you fit into that category, I am envious. "Oh..Look at what this costs". But, as far as sound goes, is there really any tremendous benefit to spending mega dollars on equipment? I single out turntables because it's one of pieces that can demand those big dollars. One who can afford expensive tables probably has the funds for other expensive components.
   Look at this table. For $650k I wonder if it sounds many times better than the one I have.....

It's a hobby for some
it's a sense of ownership for some 
its a competition or technical improvement as hobby for some.
it's experimental journey for some 

what is the aim for owning and upgrading  the system is quite important. do you have friends and mentors who knows how to play it know hat they doing . or just depend on reviews and suppliers. that will somewhat determine the way your approach the system.

going all out can be very frustration. say Wilson. magico. focal utopia. that's a difficult difficult speaker to match and get it right in a room. do you have a good room? Will you build a good electrical system? do you have good peers that have excellent knowledge to advise on investments.. this 3 speakers for example are natoriously difficult. money room mind and friends have to be ready in order to work. easily in the 500k region. 

But the most value for money for a high end could be kharma s7s with zesto prepower phono or goldmund. relatively very easy and can do all things. less than 100k. very difficult to beat price performance in high end. relatively much much easier to hit peak performance. going higher not necessarily better or easier. to hit the 500k mark performance the model is veyron kharma. I like this system best. can do every thing very well. easy to drive. easy to get the performance. 

at that level room is very important.. first the room. 

or must must know what speakers works with the room. that's the best approach. and mix it well. all system have magic combo.... find that out. eg zesto kharma. Wilson McIntosh. then the front end is whatever.. 

electrical system. room. setup. matching components all must at a adequate level to hit the optimum performance . and 99 percent of people do not know how to setup speakers. go to a show.. I count maybe less than 5 that's good rest is mediocre. that's the one of important skill and you can't learn it alone and Alot of misunderstanding. no system is bad only bad choices 

can always go for cheap combo style.. then it doesn't hurt if it's not that optimal but still satisfying level. many roads leads to rome most important things to me is toe tapping music and happy.
