How would you prioirtize?


I have been following this forum for about a year now and it has definitely helped me improve the sound of my system without much expense.  I now find myself ready to step up and spend some money for the next few steps in my adventure.  I have come up with 4 areas that could help me rise to the next level.  I would like advice on which order you would take these steps.  I have ability to spend $2-$4k every 6-8 months.  
I currently love my system, but I can hear room for improvement.  With the right record, I can turn it up to around 100db and it blows me way.  Other records don't sound so great even at lower volumes.  I know that recordings differ, but the bass gets boomy and the details are lost far too often.  I can't help but feel that with improvements in my system all records would sound much better.  I want to widen that sweet-spot.  BTW I do clean my records, it's not pops, it's the richness, details and bass definition that is off on some recordings over others.

My system so far:
  • Turntable: Thorens TD:150 / original Kugel arm / DL 160 re-tipped by Sound Smith / on springs-maple board-springs.
  • Power: McIntosh MA 8900 / original power cable / orange fuse (it does make a difference)
  • Cable: Blue Jean 12
  • Speakers: Belle Klipsch / ALK Extreme Slope crossovers / Dynamat dampened / on Hardwood sprung floors away from side and back walls / toed-in.  My system has been build around these 70's era speakers.  I am emotionally attached to them, they have a great story.
  • Room:  25' x17' open space and lively / slanted ceilings / 3 windows on one long side / carpets and curtains.  Listening couch is 9' way from speakers, somewhat mid-room.
Below are the items on my list of improvements in no particular order:

  1. Source: a. Replace the arm on the current TT (AMG 9W2 is an easy swap I am told).  b. Replace the whole rig.  I have always wanted to have a Thorens TD-125 and I am in contact with Dave from Vinyl Nirvana.  Besides being the same vintage to my speakers it has a more easily swappable arm-board.  Arms on my list include Audiomod, Origin Live, Groovemaster, SME, Thomas Schick and a few others.  IMPORTANT:  I got ahead of myself and purchased a Sound Smith Zephyr MMIC that I would like to use on the next arm.  It was too good to pass up...
  2. Phono Pre:  I am most interested in Decware and Herron.  Decware would need a Step-up transformer for the Zephyr MMIC
  3. Isolation:  Solidsteel wall shelf for the TT.  Townsend speaker bars for the 18" x 29" base (I don't think they make podiums that big).  I was originally going to put them on Pavers, but I feel that I should go big after hearing reviews on the Townsend ability to isolate. (buy once buy well)
  4. Cables and other items:  Power cords, better speaker cable, other isolation, room treatment.
Thank you for your time and helping me wade through his information.

@edgyhassle for improving the bass, I'd recommend thick corner/bass traps. The brand doesn't really matter, as long as it is thick and actual absorption (with data to back it up, like GIK ). There are a lot of products out there that are advertised as acoustic treatment or acoustic panels that won't really do anything for bass.

It's also very possible your room is hurting the clarity and detail that your setup could produce. Echoey rooms are notorious for making it harder to understand voices, and of course that applies to other sounds as well. In addition to acoustic treatments, just regular furniture and filling the room with stuff can really help with that. Adding heavy drapes over the windows is better than nothing.
@mapman Yes sprung floor, plywood hardwood planks between suspended beams.  Prior to adding the springs you needed to be careful on how you approached the TT for it not to bounce. I would tiptoe.  Now it is good unless I jump.  No echo clap, learned this one from my friends at Meyer Sound in Berkeley.  Furnishings, carpet , curtains and shelves of records seem to help control the sound.  The walls do need help.  I definitely need to isolate the speakers, thanks.
@erik_squires  Thanks Erik, thankfully I can adjust attenuation for tweeter and squawker with the ALK crossover, makes it easy for any room treatment changes and absorption.  I have played around and gotten creative with treatment using cloth screens to see if it makes a difference...it does.  More fun ahead.
My bad- too late to edit, don't want to remove a whole post, but I screwed up, the Herron does NOT use an op-amp! The MC stage uses FETs that are arranged in a unique triode mode.
that didn’t take long.....

have you figured out what the NAND gates do ?????


You got a lot of good suggestions. A quick and easy and inexpensive thing that will help improve sound quality is to get rid of those blue jeans speaker cables.  I am not a proponent of expensive cables, and BJC makes some decent cables, but when I tried their speaker cables they seemed to suck some of the life from the music.
