Looking for a true upgrade in sound quality

I added an ANSUZ MAINS 8 with active Tesla Coils that actually change the structure of the current going into all your electronic pieces and it's the single biggest improvement in sound I've ever added. Mike@ Hi- Fi Loft  NYC.

Adding a passive filter right before the Lumin should smooth out / improve the sound. I would do this before you spend money on a DAC.

I don't have enough $ to recommend a nice DAC but I hear lots of talk about Laiv, Holo Audio and others, tubes or no tubes. for example.  Sure, the signal comes from a cheap box somewhere but once you get the sinal in your house you need good solid connections and I use contact enhancer.  Sometimes the connections can oxidized otherwise.  Noise filters and a power conditioner helped as well. I am assuming you have updated power cords.  I also isolated each piece.  You can spend as much as you want on filters, etc.  A separate DAC is not a waste either. 

The rest of my system is pretty decent. It consists of a Modwright KWH 225I integrated, Tyler Acoustic Woodmere II speakers, an OPPO 105 for disks, Panasonic SP 10 TT with Dynavector SUT and Ortofon MC10 cart. All synergistic Reasearch Tessla apex cabling. Stereo Rythmic F12 subs. Room is lightly treated with GIC bass traps in front corners and some homemade absorption at first reflection points. The veiled portion of the sound is in the mid to upper midrange. Thanks, Allen. 

I forgot the Puritan PMS 156. It sits behind my rack, so I sometimes forget it's there.
