I'm using a Trafomatic Aries with my lore's with vintage Mullards and find the combo perfect. I have similar tastes to you and the Aries constantly surprises me with how well it can punch out the rock/pop. On jazz and vocals it's just magic. It took for me to get my head around 6wpc being enough. To the point I purchased a used Cayin A50T to see if some more power would be better. It wasnt long before the Cayin was up for sale again.
