Looking for integrated better than my Rogue Sphinx
https://en.wikipedia.org/wiki/International_Audio_Group Melbaguy1. Where did you hear that Luxman was PRC owned and manufactured? Important to me since I am about to buy a Luxman amp! It seemed to me that when I was researching the brand that they were pretty open about what they made in China (L-305, SQ 30) and what was made in Japan. |
To Lowrider, I used to know much more about the advantages of a high current amp and high damping factor. I am NOT sure they are related. My understanding is that high current amps produce a stable output of power that is coherent across the amp's impedance range A good choice for electrostatics, and planars, ribbon and piezo electric tweeters. Whereas, HIGH DAMPING FACTOR offers much greater control over woofer movement allowing for tighter and deeper bass. However, that said and assuming you are right, what high current integrated amps are on the market that also are very good in other areas of performance, e.g. highs, transparency, overall musicality?? If you know of a few, please let me know. In the meantime, I shall stay the course. I am not in a hurry to abandon the Rogue Sphinx, and not entirely sure the amp is clipping at high volume settings. |
As you know, it all has to do with amp/speaker matching and I don't believe the Sphinx can deliver enough current into a low impedance load. My understanding is that high current amps produce a stable output of power that is coherent across the amp's impedance range Yes, that's true, but what if the speaker load is not stable? An amp that delivers high current can drive low impedance spikes in the bass frequencies with authority, and will have plenty of reserve power so that it does not go into clipping. There will be no distortion and the speaker will sound more dynamic. It will handle transients at all frequencies with power to spare. An example of a high current amp is one that can double it's power from an 8 ohm load to a 4 ohm. e.g., 300wpc/8ohms, 600wpc/4ohms. I don't think high current and damping factor are related, any well designed amp can have a high damping factor. A driver with a voice coil is in a magnetic field and for each motion, the coil generates current to the amp. The damping factor is like using the brakes on the voice coil and driver. Jim, you don't need an amp that doubles it's power to drive your new speakers, but you do need a bigger amp, at least 200wpc. I've always owned separates, but maybe look for a used Music Fidelity amp. |
