| Bandwidth question? Orpheus10, We're all talking harmonics here. I mentioned summing of harmonics twice while Al mentioned it also few times. Highest fundamental is around 8kHz (church organs) but most often it is only up to about 2kHz as it is shown in this interact... | |
| will different lengths affect sound I screw-up numbers in my last post - 54 deg should be 45 deg while phase difference between 10' and 20' cable comes to 12.5 degree (assuming resistive load of 4 ohms).arctan(2/4) - arctan(1/4) = 12.5deg | |
| Bandwidth question? Magfan, my class D Rowland 102 has 5Hz-65kHz -3dB bandwidth but I'm saving my Pesos for Rowland 625 with small possible temporary setbacks in the future like divorce, bankruptcy and foreclosure. | |
| will different lengths affect sound Much simpler explanation than transmission line analysis: Inductance of straight wire runs in order of 400nH/ft. Inductive reactance of 10' of speaker wire (20' counting both ways) at 20kHz is Xl=2*pi*20e3*20*400e-9=1ohm.Difference between 10' and... | |
| Bandwidth question? "Why 10 times the audbile bandwidth is neccessary" - Because of phase shift. Rule of thumb says that phase shift at 1/10 of -3dB cutoff frequency is about 5 deg and that might be significant for proper summing of harmonics. | |
| will different lengths affect sound If you believe that one speaker cable has different sound from another then this sonic signature will be proportional to the length of the cable. Sonic difference will be very small and you can probably convince yourself that there is or isn't any... | |
| It's all local now Rok2id - Yes, it was special. Young daughter of my friend said to me "you guys were lucky to live in times of all these great bands". | |
| Bandwidth question? Magfan,That's true, but sensitivity of the amp does not end at -3dB point. Also antenna reception still exists at 1/10 of the wavelength. If we take, in your example, level drop of 20dB/decade it will be only -43dB at 10x10x150kHz=15MHz. Your full... | |
| Bandwidth question? I agree that most of us can hear only up to perhaps 15kHz but higher system bandwidth guarantees low phase shift. For instance my Rowland 102 amp has -3dB bandwidth of 65kHz but at 15kHz has phase shift of about -20 degree. Even at 10kHz it is sti... | |
| It's all local now "You can't be in it because you really expect fame or fortune"With exceptions: Rolling Stones made $558 million between 2005 and 2007 on "Bigger Bang" tour. Previous "Forty Licks" tour brought them $200 million. They love to play, I'm sure, but $7... | |
| It's all local now If I remember correctly The Beatles started in 1962 but got really popular in 1964. Last concert was two years later and since then the best material was released in the studio only - no chance to listen to most of great records at the concert (st... | |
| WAV vs. FLAC vs. AIFF Steve, I don't understand why SSD could be better. Music data on HD does not contain timing information. As for transfer rate required (1.4Mb/s for 16/44.1) it is a tiny fraction of the slowest HD interface. Also, compressed files would transfer a... | |
| Can the copy sound better than the original? Ths364 - It can be also, that many ripping programs like EAC or MAX go many times over the same sector until they obtain proper checksum. CDP cannot do that, working in real time, (at least most of them) and interpolates missing samples. That way ... | |
| Best product/way to clean CD laser lens? I use ALLSOP ULTRA PROLENS CLEANER (CD with micro brushes) andMAXELL Blu-ray Lens Cleaner (Wind Funnel - touchless)Maxell has hole in CD that creates wind blowing dust off the lens without touching it. When it is not enough I use ALLSOP. | |
| If you could bring back one great artist that has I'd like to make a comment about Jimmy. I do not consider him a best guitarist (many better before and after) but I admire raw power and explosiveness he delivered. I like HIS music, guitar playing, singing - whole package. Please do not classify ... |
