Add Mahler's 8 too, if you don't possess .... thats monstrous!
I'll add that to my list of future purchases !
Hope you have Number 2, which is the other
huge-scale symphony. No 1 was my Mahler introduction and still a firm favourite. Better go for a complete set! On the other hand, and I'm not a big,
serious listener, I can really see why the big, serious listeners collect multiple versions, They are amazingly different. I go Bruno Walter for No. 1: the almost
sinister sound of the string background at the start is quite something. Great audition piece: if it doesn't make your skin tingle, don't buy the speakers! Also, the power of huge choir singing softly, when they enter in No 2, and then the almost-cinema-music bone-shaking bass of the organ in the finale.
You probably know these pieces already, and I'm sure you've auditioned/heard/owned many more speakers/systems than I have. But I thought I'd mention them anyway
Good luck with your sale and subsequent purchase.
