Okay so early verdict.
Bookends is incredible. Huge huge stage and great bass and punch. However I have not heard the RKS so I can't compare.
Purple Rain is also really really dynamic with great punch and stage. But I can tell where KPGs is going to better it. The vocals. There's definitely an inherent harshness to the driving aspects of the vocals that I'm sure KPG will have softened. But that being said I can't wait to compare the two because this does sound really really good. Much better than I expected.
So Bookends and Purple Rain were both better than I expected. Not thin at all, great low end, great punch and separation. Both fantastic
The Slider. Er... don't particularly like this one. I find it soft and muddy. Very little punch or separation. Compared to the stream it's falls pretty short for me. But it's still a great player copy, just not gunna be the end game copy.
And the Flag Series Rubber Soul... basically the same thing as The Slider. It's fine, but it's soft and doesn't have the separation and punch of other versions. I can see why people don't like this version. Again, totally good player copy but not gunna be the end game either.
So all in I was hoping for 3 out of 4 being great, got 2 so it's cool. It'll be fun to listen through the whole albums. I only had time to spin a few tracks from each.
