If the tube amp is happy with the load, IME you won't find a transistor amp with more slam. You don't need a super low output impedance to control 15" woofers either! Its all about how the amp interfaces with the load. more:http://www.atma-sphere.com/Resources/Paradigms_in_Amplifier_Design.php |
I listen mostly to rock, and haven't found any solid state amp that makes me as happy as a good tube amp. Bass isn't all there is to rock - rock benefits just plenty from tonal accuracy, and to my ears a good tube amp excels at accurate tonality. On a good tube amp, guitars it can sound like there are guitar amps in my room - I love that! |
Mapman, I don't know how many times I have dropped this link but here it is: http://www.atma-sphere.com/Resources/Paradigms_in_Amplifier_Design.php In short, damping factor has little to do with getting bass, in fact if you have too much that is worse than having too little. And by too much: let's put it this way: There are no speakers made that need an amplifier with a damping factor of over 40. Its that simple- all speakers made are overdamped (not enough impact in the bass) if the amplifier has a damping factor of over 40! If there were no 4-ohm speakers, then there would be no speakers that needed over 20, the 40 figure only applies to 4-ohm speakers (because 'damping factor' is measured relative to 8 ohms). I know this is hard to digest and believe for some who have become enamoured of the numbers on a page, but that will not change the reality. You don't need an amplifier with a high damping factor to play really good bass. Let me give you an example. Sometimes I don't have an amplifier at home, because quite often I am playing a demo amplifier anyway. If that is the case, I have a set of adaptors that plug into my interconnect cables so I can use my preamp to play the speakers. You read that right: my **preamp**. Yes, its pretty gutsy, and can actually play a 16 ohm load which is what my speakers are. Yes, it is limited in volume but it sounds fine- no lack of bass at all. My speakers have dual 15" woofers. Point made?? |
"There are no speakers made that need an amplifier with a damping factor of over 40." Maybe. 40-50 was the minimum I was shooting for for my OHM 5 series 3 speakers that seem to benefit from higher damping. THe BC ref100m amps I went with and use have 1000 damping factor. WHen I first fired them up I thought to myself "what happened to the bass"? WHat happened was it was there as much or more than ever but also more tight, controlled, and articulate than ever as well. Definitely different than most bass I have heard elsewhere, either tube or SS. I've been running these for coming up for 2 years or so now and feel more than ever that I would not want to give up the bass I am getting now which is some the best I have heard anywhere in a home system to date. Atmasphere, of course my system no way shape or form resembles the type of system I know you advocate in line with your products. I have heard your amps as well and they were very good all around including bass. WHich is better? I don't know. In lieu of an a/b test having heard both at different times, I can say that they are much different and both good in different ways. |
