| Rowland 625 versus Audio Research DS450 Rowland 625 is not a class D amp. It is class AB design with no global feedback and SMPS supply. | |
| At what distance are balanced XLR cables needed? Atmasphere, unfortunately I don't like gain at 60ohm position. Not many solid state amps have 60ohm output impedance while the most of them cannot drive 600ohm. The reason for that are op-amps used. Only few like LM4562 or OPA1611/12 are designed ... | |
| Why the obsession with the lowest octave Mixing two different tones is another story but the lowest frequency is called root and the rest are overtones that are higher. When you play instrument with complex harmonic structure (typical for percussion instruments) like piano - each key pro... | |
| What do they mean for "long throw driver"?? Just one comment about magnetic gap. It is very narrow with typical (overhung) design where coil is much longer sticking outside (overhanging) of magnetic gap. Only part of the coil is at given moment in the main magnetic field. The other design -... | |
| At what distance are balanced XLR cables needed? Output impedance is not that important within certain limits. My Benchmark DAC1 has output impedance values from 60 to 1600ohm dependent on output divider jumper position. Benchmark recommends for 1600ohm output maximum cable length of 26ft - assu... | |
| At what distance are balanced XLR cables needed? "The 99.99999% figure quoted for purity is outright preposterous"Nordost uses 99.999999% pure copper."BTW this is why you don't see copper wire that is Teflon insulated."I just look at my Satori speaker cables that are 6N copper in Teflon. You can... | |
| At what distance are balanced XLR cables needed? Eldartford, 600ohm is output impedance and 600ohm is input impedance of power amp. Because of 2 to 1 division of the voltage output voltage of the driver (driving 1.2k total) has to be 2x higher - being equivalent to nominal signal driving 600ohms... | |
| At what distance are balanced XLR cables needed? I would suspect that bigger current would cause bigger voltage drops on said junctions (or impurities) everything else being equal. 600ohm must be not very common since I've never seen anything that can drive 600ohm without distortion. For now I w... | |
| At what distance are balanced XLR cables needed? "cost of the cable will have no bearing on the sound if"Can you explain why purity of metal becomes unimportant in balanced configuration? | |
| Why the obsession with the lowest octave "Having a tweeter than goes well above the audible frequency range just allows a better reproduction in the range that you can hear"Not necessarily - it might distort more at few kHz range. | |
| At what distance are balanced XLR cables needed? Kal, Absolutely. Why not to use balanced if environment is known to be noisy. My Rowland 102, a class D amp, has only balanced input connector - a mature decision on a side of Jeff Rowland. Balanced has also two practical advantages - it won't dis... | |
| Looking for speakers I bought for $3k 6-month old dealer demo Hyperion HPS-938, amazing speaker. Same room size with tall (cathedral) ceiling. Read reviews at hyperionsound.com | |
| At what distance are balanced XLR cables needed? Al - I'm not sure if metal purity or dielectric absorption or capacitance play role in any particular setup either, but if they do - I can't see any reason why it would be different for balanced vs unbalanced cable. Balanced versions are always sl... | |
| Why the obsession with the lowest octave Mechans - Quality of the bass is more important than extension IMHO. My current speakers have larger drivers and more volume than my old speakers but extension is slightly worse. Dynamics, attack and decay of the bass, on the other hand, are much ... | |
| At what distance are balanced XLR cables needed? Eldartford - you can spend arm and a leg for a balanced IC as well. They're also made of fancy materials - both metals and insulation. There is no reason why it should be different IMHO. Purity of metal still applies since impurity reside between ... |
