VAC 30/70...pick your pre?

Walter, 
Excellent logic in deciding to get the speaker upgrade package.  There's no doubt in my mind that better quality wire, inductors  and capacitors can make a very noticeable improvement in the sound.  You might as well get it right initially is my perspective.  The up charge is quite reasonable for the higher quality parts.

Totally agree Walter about Line Magnetic, I have the 518IA as part of my main system, wonderfull sounding especially with insertion of NOS 6l6GCs, 5AR4 , anmd 5751s.

Previous owner of a Vac 160i as well which I really liked and have not heard any SQ deficiencies with my LM 508 IA. Those of you with the 508, have you tried any other 805 Tubes? I tried the Psvane which were better in every area but they only lasted about 3 mos; one tube failed to bias correctly...

Wig, nice to hear as the 160 was on the list. Helping solidify the decision and now Im torn between the 508 and 219 at this point.  

Phaun16,
Is there a reasonable way for you to find a Line Magnetic dealer who has both amplifiers and plan a trip specifically to hear them? I feel it'd be well worth the effort.  I believe that you'll be very happy with with either amplifier.
