| Subwoofer Wolf_garcia, I agree, there is not much activity at 30Hz. Another story is frequency response in the room. My room amplifies about 30-35Hz extending response a bit, but extension is less important to me, than quality of the bass. My speakers... | |
| More resistance is less load?? With common 60V transistors (like 2N3055) highest supply would be +/-30V making maximum RMS power with 16ohm speaker only 28W. | |
| More resistance is less load?? A long time ago amplifiers had a great deal of trouble dealing with low impedances and high power. I’m not sure why. Output transformer can be designed for any load. Perhaps higher impedance speakers had less distortion? Perhaps it was difficult ... | |
| More resistance is less load?? AFAIK long time ago all speakers had higher impedance, mostly 16 ohm but some even 32 ohm. Linearity would be much better with underhung motors (coil within a gap) instead of commonly used overhang motor design (gap within a coil). Only few manuf... | |
| Fiio x3ii or Fiio x5ii I use it as stationary asynchronous USB DAC/Headphone amp. | |
| Fiio x3ii or Fiio x5ii Perhaps Oppo HA-2 for about the same money might be to your liking? I have it and the sound is outstanding.https://www.oppodigital.com/headphone-amplifier-ha-2/ | |
| "High End" Bluetooth Receivers - Snake Oil? I'm don't know what is available, but I cannot see reason why not. CD quality requires bit rate only of 1.4Mb/s while Bluetooth can go as high as 25Mb/s. Transfer itself doesn't matter since timing is attached later (data transfer in packets). ... | |
| Long XLR Interconnect Cables I had substantial improvement replacing short 0.5m XLR AQ King Cobra with AZ Absolute (silver). I suspect, that improvement would be greater for longer cables. Both cables were natural sounding, but Absolute was cleaner (more refined) and faster. | |
| ... how important is Damping factor in determining what amp to buy Al, I agree, but when people refer to DF (including this discussion), they mention control of the woofer. The effects of complex load should diminish when source impedance is 10 times smaller than the load. DF=20 should be a good choice. At th... | |
| ... how important is Damping factor in determining what amp to buy Vibration of the speaker membrane, without signal, causes back EMF producing current that flows in opposite direction working against membrane motion, hence damping vibration. This current (damping effect) depends on the total resistance in the ci... | |
| Who tried Class D only to return to S/S or Tube There is only about 1% of 500kHz switching noise on the speaker cable, and that is absolutely irrelevant. Placing an ear next to tweeter proves only that people cannot hear 500kHz (almost complete silence). Modulating 500kHz by the tweeter would r... | |

| Dual Differential / Balanced? Thank you Ralph, I will keep reading more. I use fully balanced stages in low level amps without any ground reference. It has bandwidth of few kHz only, but full scale of the signal is in single millivolts. At the end A/D converter with differe... | |
| DAC or CD Player. Help! jamcl63, Welcome. I'm in this rabbit hole since 2005 for the same reason - to learn. You pretty much answered your own questions. Yes CDP has its own D/A converter and analog electronics but it also has digital output providing serial stream of... | |
| Dual Differential / Balanced? Charles1dad, Thank you. I often engage in discussion with Al or Ralph to learn more. It is difficult to understand why particular architectures are being implemented since it is often fueled by demand. I like to understand technical merits of d... |
