    Modern, low-power amp

    I'm looking for an exquisite modern 10-25 wpc tube or class A amp that controls for turn-on and turn-off transients, preferably, but not necessarily, with balanced inputs, to use for a tweeter amp. Any ideas or suggestions would be appreciated.

    Edit: This is not specifically an offer to buy, so I did not post in the Marketplace forum. It'd be fine with me if this turned into a discussion of tweeter amps in general.

    I agree with you, low power amps tend to sound sweet in the VHF. Another spec that is important, IMO, is input sensitivity. .75v to1v input sensitivity is the right way to go, if you use an amp with say a 1.5v input sensitivity you will have to push the signal alot harder as as you go up in frequency the signal isnt as strong as the lower frequency signal.

    Ian Mackenzie highly recommended Nelson Pass First Watt to me some time ago. They are Class A Low power, but, expensive.

    Doug/Dave,

    You can enter the realm of hi end audio with only a modest outlay.

    The F4 (power follower) for example has been published as a diy project.........I have not had time to build mine yet.

    There are some interesting class T amps pumping out 15 watts or less that reviewed reasonable well and are quite affordable. Do a google...

    I agree; chip amps have come a long way. I would just caution the noise that most are capable of, and suggest dealing with the RF/EMI the best you can. My class D's were noisy at first.

    Pass used Alephs on his Raven R1's, too, I read somewhere..

    In the world of tube amps, the 2a3 is queen of the HF.
    Relieved of it's midrange and LF duties- it's one amazing tube.
