Well, it's hard to say exactly and here's why: I changed cartridges, so it's not like I can truly judge the sound difference to be a result of the tractor setup. Also have to consider that a new cart needs to break in.
Additionally, I ran out of my 'personal time' and am now sort of on 'family time', meaning I can't do any critical listening just yet. But I am playing an LP over and over, running downstairs to re-start it every so often (trying to accelerate break in of the new Dynavector 20XL) and my first impressions are that it sounds *very * good....
