I took a vinyl copy of the Telarc 1812 when I auditioned the Holbo turntable! Almost all my vinyl pre-dates CDs, and I have a few dbx companded records which I can no longer play because my dbx capable player got stolen, together with everything else just before I did a round-world business trip. I listened to Quad speakers in LA and Salt Lake City, then visited Peter Walker of Quad in the UK who told me he thought classical CDs were brilliant. I bought Quad pre-amp, amp and ESL 63 speakers in the UK and an early Philips CD player in Singapore, plus every CD that I could find. I went through Australian customs with the amp in my suitcase, the pre-amp in my briefcase and declared the CD player. The customs officer invited his mates over, and as they opened the box, about 50 CDs fell out. It was the first CD player they had seen. No worries, mate, enjoy!
I had to ship the speakers, and there was plenty of weight available, so my dad gave me his old Garrard 301 which I have just started to restore, hence I am buying selected vinyl again. (Wollongong City Library had a huge selection of classical records which they lent for free so not much need to buy any in my good old days).
There is one Decca (London?) vinyl recording which I would use for auditioning, if I could get one at a reasonable price. It is Benjamin Britten's recording of his Young Person's Guide to the Orchestra which dates back to Decca's heyday around 1963. It has never been out of the catalog, at least in its digital form. Under 20 minutes long, it covers every instrumental section, until subsiding to almost inaudible triangle tickles then rising to a crescendo of complex cross rhythms. A serious critic has said it is his favourite piece of classical music, to boot! It is the only piece of music I needed to play when considering purchasing my KEF Reference 1 speakers - my dealer had it already queued up on his streamer!
