If you were serious about sound you would...

That list that you mentioned is not high on in any category ,andi have owned a audio store went to many audio shows  and built many audio systems. System 

synergies by far the best important , and many pieces of equipment I have seen in mastering studios is just not that good , for example many use Mugabi Audiocables 

or others it’s not that musical. Now Bricasti is a solidAudio brand that started in mastering studios and is well respected . There are many Loudspeakers -Audiophile that use better quality  Loudspeakers for much less monies. 
Musicality is what counts most ,,the mastering is sometimes. The biggest limitation 

who mixes the recordings . Vacuum tube has always given the most natural

presentation, playing guitar pretty much the vast majority of amplifiers are Vacuum tube , even Vacuum tube mikes Many use .  That’s why many older recordings sounded more natural , the majority of Beatles ,masterpiece Pink Floyd Dark side of the moon , solid state can be verygood , look at Manley again Vacuum tube mixing boards,

@roxy54 Not bragging at all nor did I say I knew everything about sound. I'm just saying something that is practically never discussed here and that is the fact that you can't make the signal better (more accurate) than the original so why not use the equipment it was recorded on, in most cases that equipment is not as expensive as hi end audiophile equipment. 

@audioman58 Sorry I'm not getting my point across to you at all. I'm saying that since audio accuracy can't be more accurate than the original recording by definition, even if the recording is done on sub standard studio equipment it is what the musician and producers and mastering studio OKed. So why is it that professional gear is so rarely used in audiophile systems. Simply get the equipment from a top 10 studio in the world (maybe not Abby Road because of all the product placement) but then you have a very solid playback system. Room acoustics, looks and such are not part of the playback system. Why is it never considered? I'm not talking about the most accurate audiophile equipment or a debate between tubes and transistors, tubes are used in microphones in great studios but that is about all. Of course there are exceptions to every idea but hopefully this group is smart enough to understand that the exception is not the rule. 

@bikeboy52 Yes you nailed it I don't think the vast majority is serious about sound they are serious about feeling good about music and enjoying it satisfying their own preferences. You seem very confident in your assertion tell me why I'm wrong. Don't forget I'm talking about having the most accurate playback system.

@p05129 Just go to TAS and see what amps the editor uses in his reference system BHK 600, he could use and have used practically every amp there is but he chose that one, they don't suck. I do have to say the BHK Preamp is noisy I've had 3 of them and I can't get rid of it because it sounds nice (not accurate) but nice and it has 5 XLR input channels. The new DAC is a work in progress but has potential to fight way above its price, the SACD Transport is great. PS Audio is interesting because they are right on the edge of being great with most everything they make.
Thanks
