I'm told that piano music is the ultimate test for digital HiFi. Is this so, and if so why? My brother in law has been auditioning fairly hi end (to my wallet at least) CD players and always listens to piano music when auditioning. It seems he may plump for the AMR 777 CD. I'd not heard of AMR until yesterday.

I used both piano music and classical-based video game scores for my primary headphone comparisons when I was testing the Sennheiser HD600, the Sennheiser HD250II and the AKG K550 against one another. There are many nuances and microdetails with both piano and other orchestral instruments making it perfect material for revealing how close the transducer can get to reproducing real sound. After they had all had some use, the differences between the headphones was very apparent with the music that I listen to. The K550 was neutral but flat and uninvolving. The HD600 was involving but slowed, glossed over, had upper bass protrusion and a lack of frequency extension, although the midrange was really beautiful. The HD250II was both neutral and involving. Because the piano has the largest frequency range of all acoustic instruments (I think??) with REAL tonality, it will test all attributes of a transducer, not just a few properties. Combined with all the low level detail in the tracks, only sensitive balanced transducers will be able to convey it all.

Yes, I think it is so. But the recording has to be well done also. Piano music is a good test because the sound of a piano is made up of fast transients. Getting transients right is critical when reproducing sound. Classical acoustic guitar is also a good test.

I tend to use orchestral music in general as a system tester whether piano, string, etc as I find it easier to follow the start/stop/decay of notes. I smile when I can 'see' the musician playing the notes rather than just hearing the notes being played (if that makes sense)

I tend to use any good recording of real instruments in a believable acoustic in the first instance. But piano is especially good - particularly with turntables as sustained notes show up speed problems.

BTW I see that AMR CD player uses valves, for that "vinyl quality".

To be honest, I don't even understand why anybody uses CD players anymore... What a waste of money... Confused I keep all my CDs immaculate in their cases as a back-up and only ever put them in a disc drive to rip them. WAV or FLAC file retrieval from a HDD or flash device should be equivalent to the CD reproduction, perhaps better with flash memory as you likely eliminate some electronics from the signal chain input, which can only be a good thing. Sometimes less is more.
 
If he wants "vinyl quality" then he should buy a vinyl turntable instead. Wink
 
P.S and I'm inclined to believe that he should probably buy a Reflex M along with it as well... Wink

Ash, youngsters like you and I can take CD ripping and FLAC/ALAC computer based music in our stride, but it's not for everyone especially when the spouse needs to be comfortable with it. Having said that he's not closing the door on computer based music; one of his selection criteria for a new CD player is that it has digital inputs. As for your comment that "he should buy a vinyl turntable", there's no need, he already has one that I could only dream of owning, but there is probably room for a phono stage upgrade.
