What difference do you hear between Reflektor 75 HGs and 61 Valvo CCa with your LCD-2?
I'm actually pretty terrible at describing sounds I'm hearing. I tried writing my thoughts about 4 times and deleted it because it made no sense.
Here it is in a nutshell...
75 Reflector HG: accurate and resolving, doesn't add a lot of color to the sound, very solid state-like. Extreme detail and speed for a tube.
61 Valvo CCa: very resolving, fuller but less accurate bass, lusher mids, a bit more "crisp" high-end. It's almost like I have a slight U shaped curve set in the EQ when I listen to them with a tiny 1-2db hump in the mids.
I know that's a pitiful description, but there it is. It makes sense in my mind though, because I actually do turn up the volume on the HGs a bit to get the same perceived sound as the Valvo's.
It's like Mounds vs Almond Joy. Sometimes I want the almonds, sometimes I don't, but I love them both. Haha.
(and before someone asks, the Reflektors are the Mounds and the Valvo's are the Almond Joy... think about it)
EDIT: One more thing. What I like the best about these 2 sets of tubes is their amazing sound stage. They just sound so open and natural. A lot of tubes sound kind of hollow or have one thing that's annoying about them... These tubes have nothing that annoys me or I feel they're lacking.
