My main reference record is the Tears for fears "Seeds of love"-album, and especially the tunes "Woman in Chains" and "Sowing the seeds of love" but also the "Year of the knife" track. Simply because it is well recorded, even if it is a full digital recording and not analogue, and a dynamically sounding album. I like it very much and it was this album that I selected my first stereo with in the late 80's, yes I bought my turntable and first speakers to this album.. the shop had it on vinyl, but I had it on CD at that time (I bought the vinyl version later).
I also have some Beautiful South singles, like "You keep it all in" and "I'll sail this ship alone". Good analogue recording with some warmth to it.
And then I have the Amazulu album, with "Montego bay" on 12".
Recently I have added the first LP in the 3-LP box "Pop Art", the singles collection by Pet Shop Boys.
Those together reflects my broad musical style and if the system works with all those in a great way, then I'm hooked.
