I am wondering just how careful you have to be in this. For a good many years I have been used to either the smoothness of the Pioneer PD-S703 with the Kenwood 3020SE coupled with Mission 760 speakers listened to at 'sensible volumes' in our living room or...the Marantz CD63 KI Sig with Audiolab 8000S coupled with TDL RTL2 speakers played at a greater volume in the front room. Seemingly, both combinations had their merits, the latter having the benefit, I believe, of better acoustics as well as being roughly twice the price. I was comfortable with both.
But within the last 12 months I have had my horizons broadened and my listening tastes have come under scrutiny. Not only have I begun to listen to music I would never have considered previously, but I have heard completely different presentations according to the kit and its connections. I am still not sure where my preferences actually lie. I think I prefer a well-rounded mid-range with some warmth, but with a clear and precise top-end. I like to hear depth and breadth. I like a solid bass but don't require it to be powerful (not least because we have neighbours!)
The bi-amped Audiolabs are doing a solid job of controlling my current system, seeming to balance things out nicely. Despite recommendations, I was disappointed to find that I wasn't bowled over by the Pioneer A400 even though it gave the Audiolabs a run for their money. Now, at last, the Marantz PM66SE KI Sig puts in an appearance on the stage. From the brief sound check I have had time for, it is well-suited to my taste. From this Sunday I will have opportunity to do an in-depth try-out.
Initial impressions of a comparison between Pioneer and Marantz (temporarily linked up to a CD63 KI Sig and TDLs in the front room) were that the Pioneer gets loud very fast (before 9 o'clock on the dial) and has a forward, brash and lively sound. The Marantz only begins to deliver beyond 11 o'clock and shows much more restraint and refinement. The Pioneer has the character and charm of an exciteable puppy, whereas the Marantz, on first listen, has a more feline sophistication. I can understand how the Pioneer can be ideal for dynamic rock and pop-orientated music, whereas the Marantz has strengths when listening to classical, vocals and the like. OK, it's early yet in my experience. But given my fairly wide taste, maybe the Pioneer will remain that bit too lively and exciteable and the Marantz will directly challenge the Audiolab throne.
