VPI HW-19 Jr. Upgrade


I am considering upgrading my VPI 19 Jr. w/AQ PT-6.
I've narrowed it down as the followings.

1. Upgrade my Jr. to the Mk4
2. Put the Scout platter and bearing on my JR
3. Upgrade to the Scout/JMW-9 and sell my JR./PT-6
4. Change JMW 10 Tonearm

What is my best bet in upgrading from my Jr.?
What kind of sonic improvement can I expect?

It would be very appreciate if you give me an advice.
Any other suggestions are welcome too.

You'll hear a notable improvement going from the Jr. to the MkIV. For all the hype over the Scout, I haven't heard one up close, but the Mk IV sounds great, and would be worth putting a very nice arm and cart on.

Bear in mind the Scout is an entirely different design from the MkIV, so if you like the HW sound and want "more of it", so to speak, then that's the way to go...I can't tell you what you want ;)
John Zurket at positive-feedback.com recently reviewed my pandafeet sorbothane footers with his VPI 19 Jr. and raved about the results:

I'm sure plenty of other products would work as well, but it does seem that vibration control helps the performance of these tables.

I started out with an HW-19 plinth and MkIII bearing and platter. Then Aries 2 platter and bearing with more sound improvement. Then I built 2" cocobolo plinth with lead load to replace the HW-19 plinth which move my TT into a whole different level. You can pick your plinth design from Teresaudio.com and use VPI platter and bearing instead of Teres. I used classic tonearms such as SME 3009, SME type III, Black Widow, and various Audio Technica Broadcasting tonearms.
I upgraded my HW19 Jr by adding the MK III platter and spindle and noted improved detail especially in the bass.
I got an email from someone here on Agon several months ago about making a plinth for the Jr from kitchen counter material like Corian(sp?). Haven't tried that yet but he claimed it made a nice improvement.
