High current amp search

Dear @soix  : I know Steve from the earlier 90's when I bougth the tip toes and through the years I listen his electronics.

The Steve electronics today not yet has the Boulder or Dartzeel status. However the Levinson 20's has it after the change of those electrolitic caps in the power supply that any one of us can change with out solder/unsolder any thing due that those caps are screwed and only need to take out the topand bottom plates to do it and the Vishay caps we can get from MOUSER Electronics for around 400.00 the 4 caps.

The 20'sare the State of the Art design coming from the legendary John Curl designer.Is a100 w.of pure class A at 8 ohms and puts 800 watts at 1 ohm and can goes even to 0.5 ohm.and in that link you can pay lower than 5K for the pair monoblocks.

It has severaladvantages a one way important for the OP because using the 20's he does not needs an external HP crossover and additional cables or the sub's HP electronics due that the amps are coupled by a cap. So we only have to change at the input circuit board the Wima 2.2uf input cap for another Wima with way lower value to have that 80hz HP filter.

@rauliruegas do you not prefer the character of your main speakers (in the upper sub bass region) to the character of your subs?

I find that if my subs roll in any higher than 40hz for general listening, 44hz for 90's electronica or a maximum of 54hz for some dub reggae, there is a sense that the subs are treading on my Focal's toes in a way that thickens the bass and is less articulate, and generates less slam.

The alternative for me would be to swap out my Velodynes for Focal sub Utopias, but two things prevent this. One is the cost, since the sub utopias are passive id have to invest in some serious amplification, especially as I'm about to add a third pair of dd18+, and the other is the disappointing on paper frequency response of the focal subs, they arent really rated much lower than the same field coil bass drivers in the Stellas. I've got used to a system that is flat to 15hz, and having lived with that i have no desire to go back

Guy asked what time it is and you told him how to build a clock

@gavman ,

Traditional Scottish cottages have 2 feet thick rubber walls??!

Does it really rain that much there? 😃

@thecarpathian oh cr@p is that what i typed?

I meant to say 'two feet thick rubble walls'

Good catch☺
