Tubesrule, I sold my Shuggies to a friend (as a backup set) shortly after my last post. They were still performing perfectly, but I was antsy to try the Psvane black-coated tubes which had just come out.
The Psvanes had better quality construction in a number of areas (heavier bottle, ceramic base, etc.) but were essentially the same sonically as the Shuggies. They are still in my amp three years later and sound very nice. And just to make sure, I occasionally A-B them with my 'reference' set of vintage Genelex Gold Lions. So far, no difference ;~)
