Watersalas-
Similar situation. I didn't even hear a 219ia until I plugged my own in. I heard the 216 which was loaded with gold lion kt88's through lascalas, and then heard a 518ia through cornwalls. I decided it would be the 219 or the 508 from there and was pretty sure either would be great and wouldn't really matter, 805's vs 845's both being praised tubes when paired with transformers that drive them properly. I'd love to hear the 508.
