What speakers?They best be Klipsch or an easy load.Look at a Mac perhaps.Do you have a preamp?I bet not,anyway,look for a Mac or Marantz receiver,a good one will run 3-700$ depending.....make sure it has good ventilation.....be prepared to lose 2 of those speakers if whatever you get runs hot......sounds like fun,good luck,Bob
I don't know whether Bryston 4B-ST can be considered as vintage. I remember reading some comments about these amps being used in some night clubs and discos by DJs, and that cigarette butts are discarded on top of them and drinks spilt on them, and after continuous play at near clipping levels the amps never failed.
Also, I read somewhere here about the Krell KAV-400XI being dropped from a waist-level table onto a concrete floor and come out fine, although the concrete floor was chipped. Certainly built like a brick.
I short out the speaker terminals while the preamp volume is up all the way as a demo at shows. In addition, I pull tubes out of the amps **while they are playing** and swap them from one channel to the other, with no ill effect or artifact at all. Is that what is meant by 'bullet proof'? or does that have more to do with what happens when you drop the amp?
Buy a pro audio amp. They're designed to take abuse in commercial sound systems and operate in less than ideal condtions of use.
However, I agree wtih Shadome that damage to the speakers is a bigger condern than what amplifer is used.
If you don't trust the operation of the system, then get a pro audio amp with built in DSP. This would allow you to set the amplifier limiters below the point of clipping or below the point at which the speakers would be damaged, which ever is less.
Something like a Crown XTI-1000 probably would be more than adequate power-wise. It is rated for 8, 4 or 2 ohms operation and has the built-in DSP functions.
Sure, but gone are the days when touring amps weigh >100lbs each for a mere 300 or 600 watts.
Heck, I've got amps that will put out 3,600 watts (if you can supply enough input juice) and weigh only 30lbs, and they're bloated pigs by today's TOTL touring amp standards.
Check out PowerSoft K20 or some of the Lab.gruppen stuff if you want to see real power in a small package.
