This system has taken years to come to fruition.  I simply love it.  I am a bare bones music listener.  I don't stream or do home theater.  Most of the components are original and have not been modified or upgraded, EXCEPT for the following: KRELL KAV250 AMP.  This is a late 90's model and had a recall in it's first year.  I had that issue resolved and recently had upgrades on all caps and resistors.  The work was done at THE SERVICE DEPT. in Bridgeport Conn.  I highly recommend them. The amp rocks and I'm good for years to come. SONIC FRONTIERS SFP1 SIGNATURE PHONO PREAMP.  I had one of the originators of this product, Glenn, at THE PARTS CONNEXION in Ontario overhaul this unit.  All new caps, resistors, and ceramic tube sockets!  It sounds wonderful, warm, yet crispy.  They also set my load and resistant settings  for my Benz Micro Glider cart, 1.1mv.  Not modified but my most recent upgrade was the AUDIO GD HE1 BALANCED XLR VACUUM TUBE PREAMP, WITH REGENERATIVE POWER SUPPLY.  I bought this from Wally at Underwood Hi Fi.  It being made in China, it was Wally's 2 year warranty that made me pull the trigger on a unit from a country that is hard to communicate with.  I am so glad that I did.  This one upgrade brought the sound of my system up by a great amount.  The amount of presence, clarity, separation, punch and energy that this preamp helped my components reveal was simply astounding.  Wally was great to deal with. Also, the dust cover for the VPI SCOUTMASTER was custom made by an Audiogoner,  whose site name is 1854K.  He did a great job.  One other thing: I use the Ultech UCD 100 as a transport that feeds the Bel Canto Dac.  I just received the SCHIIT BIFROST 2/64 and am currently burning it in.  I'll post an update on that as the Bel Canto Dac I have is 4 generations old.  The OPPO BDP-95 I use for an occasional movie, but is my second playback unit for CD's (SACD,HDCD) that I use via XLR outputs to my preamp.  All interconnects are Audioquest, Transparent Music link and Signal Cable: power cords also Signal Cable and Pangea.  Thanks VERY MUCH for looking!!
