Well... Not to be a prick, but MY system comprises of a G5000 Sansui receiver, who's price of $470 us was well worth it in 1978 to '80. And this receiver is powering a set of Canadian-made speakers (made for Sansui) from the same year, model S-40C. Now I know the receiver is perhaps not as accurate as my dad's Sansui 7070 and S-55C speakers, but the sound from my smaller speakers in a small room is very "natural" and tight. The speakers are air-suspension and well designed, so despite being 3-ways with 10 inch woofers from 1978, they have very accurate bass and a full, tonally balanced sound.
And then there are my dad's S-55C's, which are just like my speakers, only they're 4-ways with 12 inch woofers. And they too are tonally balanced with tight accurate bass, but they have higher highs and lower lows, and have a lot more detail. They reveal truly bad recordings, and truly good recordings - very little colouring of the sound. They approximate B&W's mid-level sound.
My real point is that it is through these systems that I find even the best compression encoding has flaws. Mp3 was a great theory, and was a good step in the right direction, but it has problems. Mainly that treble sounds warbled, and the overall feel of the sound is changed or lost - perhaps some of the imperceptible things the format removed were important for subliminal sonic imagery?
So far the best highly compressed format I've heard is AAC, which may not be accurate or true to the original sound, but tends to have fewer distracting artifacts in the treble and seems to retain more of the original feel of the sound. Of course the best really is both Apple and Microsoft's "lossless compression". But then we get to my biggest problem with digital sound these days: Most music is inadequately recorded to begin with.
See, I tested the claim that CD audio can handle up to 20,000 Hz sound frequencies.. I used Audacity to generate tones at the sample and bit-rate of CD. Turns out 20KHz actually is just unreadable spikes between the samples, and it isn't until you get down to about 12 or 13KHz that the waveform starts to appear. So that means digital to analogue converters must sort of simulate the high frequencies. I guess that only the fairly high sample rates available in DVD and Audio DVD format are adequate. Pity.
In the mien time, avoid buying amplifiers based on their advertised wattage. My dad's 7070 is rated at 60 watts per channel. That is a very conservative rating, whereas todays crap tends to be rated nearly 4-fold higher than the actual. Remember: If a speaker says it produces 90 db at 1 watt, in a small room you'll normally only need less than a watt per channel! Also go for sound quality. My amp only produces 35 watts a side, but the sound is hard to beat these days.
And another thing... I realize they're the latest thing, Subwoofers. And they are fine if you need to save space, like in an ebike or at a computer desk... But nothing beats all the full range of sound coming from each speaker. We may not perceive where bass comes from, but I'm sure there's a subconscious effect having the bass come from left and right speakers that gives us a sense that the sound is more real. Don't get me wrong - some subwoofer systems sound very good. Just sayin'.
And finally, I know B&W uses them, but even though B&W's speakers are perhaps the best sounding, there is one thing I would say could be improved: The ported speaker cabinet, designed to reduce mid-range and increase bass response of woofers, should be left to small speakers. The simple fact is air-suspension cabinets are the only ones capable of producing a single sound wave (outside the cabinet). Bass reflex cabinets send out the main sound wave, plus a bassy second sound wave at a slightly different time, and this muddies even the tightest bass signal. Air-suspension however can be made to have very accurate sound indeed. I'm only talking about regular linear motor speakers, not fancy ones like electro-static.
Okay, ranting complete. Back to my ebike!
P.S - Class A amps produce a truer signal than all other classes.
