The entire Bruckner repertory at this point in time is such that the choices are too varied and difficult to decide upon. If I were a newbie to Bruckner as chalkpie is, and wondering about whether Bruckner is a good composer overall, I would be cautious about spending an unnecessary amount of money and narrow my choices to buy a set at a bargain price by a conductor who is regarded as doing a good job overall in performing the symphonies better than most everyone else, simply to get a flavor of how Bruckner ought to sound performance-wise, and not necessarily make sound quality a must in my choice, which should help in narrowing the field.
Though Bruckner wrote some powerful orchestral tutti, they do not quite approach the power and do not necessarily need cutting-edge recording technology (such as SACD) that Mahler requires for his works. Years ago, I had only the now-outdated Haitink Philips and Jochum early DG sets as my two choices, but today, I certainly don't envy chalkpie's dilemma about the choice he needs to make as starter Bruckner symphony cycle set.
In making the final decision for a complete Bruckner symphony set, don't forget to consider those sets that include the Symphony No. "0".
Barry, as an orchestral musician, do you have any particular preference for a well-performed Bruckner cycle?
