I was listening to HDTracks Bill Evans waltz for Debby last night. A great deal of care has been taken making the 24/96 version of this album and it shows. The 05' really makes the bass seem like Scott La Faro is playing right to the left of you. You will love what this amp does with jazz and vocal.
Another love of mine is early choral music. I hope Andy chimes in here as I know he likes this as well but the voices I promise will have the hair on the back of your neck standing on end so palpable are they!
I am really rooting that your amp gets this gold treatment, I just have a feeling it will look stunning and so interesting that he thought about this also!
Oh, for Jazz, one last recommendation.
I purchased today from HDTracks Horace Silver's album Songs for my Father, oh boy, they have done a wonderful job on mastering this for high resolution, it sounds wonderful!
