I have the  d2000s and have had poor results with two different tube amps: first,  the hifiman you referenced  and now my Schiit  Valhalla. Best example is DSOTM which quickly turns into a major bass fartfest.  My experience is that the 2000s are better un-amped                           

  Paul Burch - Pan-American Flash

The Jayhawks - Hollywood Town Hall (2011 re-issue). Next up The Whitlams - Love this City      

The exhaust fan in a bathroom. The sound drives me batty

I bought a pair of Goldring DR150s based on a 5-minute listening test and universally positive reviews. They are pure crapola. Ear-piercing highs, sibilance, tinny, blah, blah, blah. Break-in matters not. My only true waste of money.

"bring on the Dancing Horses" - Echo & the Bunnymen

"Alright, I'm Wrong" - Dwight Yoakam

118,000 songs, 8,966 albums, 288 days of music.

"Oh Darling" - The Beatles

"Sleeping on a Rollercoaster" - Tommy Keene

"Beyond Safe Ways" - Bawl

Another vote for The Pretenders. Chrissie Hynde is one of the greatest woman rock singers EVER! Her vox are not of the soothing variety though (no hint of twee or sweet). She is a rocker who has perfected the tough/tender thingy. She is also a fiercely independent thinker if that matters at all

The Vouts - Out with a V (Tim- and PTMM-era Replacements-esque)  

"Acid bird" - Robyn Hitchcock

"Egg Shells' - Stratocruiser
