VPI Scout/Scoutmaster cartridge recommendations
When I had my Scoutmaster, I was using the Dynavector DV 20X2 Low MC cart with great results.I'm now using that same cartridge on my Rega RP6.It's an amazing cart for its price! For both turntables, I was using the Linn Uphorik external phono stage.

If you don't want to deal with network issues, have a look at the new Bryston BDP-2 digital player. Not only will it stream from a server over the network but it also supports USB devices and the new BDP-2 also supports an internal 2.5-inch hard d... 
Meridian Sooloos or Qsonix? which is better?
No comaprison, the Meridian Sooloos system is much better than the Qsonix system.You should also have a look at the Bryston BDP-1 digital player or even their newer model, the Bryston BDP-2.

Dynavector 10x5 what is next?
If you like the Dynavector sound, then have a serious look (listen) to the Dynavector DV-20X2 MC cart. I'm using it on my new Rega RP6 and it sounds amazing!

Bryston BCD-1 CD player, if you're lucky enough to find one. 
Upgrades to Analog System

Have a look at the Ray Samuels Audio F-117 Nighthawk MC/MM phono stage.It's an amazing sounding battery-operated phono stage that provides the ability to change settings on-the-fly, via front mounted knobs (no need to open up the unit). 
Rega P6 anyone?
Let us know how it turns out!
