… SET magic...
With what speakers?
Windchaser’s comment is what I’m afraid I’m going to find when trying to settle on a SS amp. I have been seduced by the Single Ended sound! The soundstage and seductive midrange is what I have not been able to get even with much more expensive push pull tube designs. The little Inspire amp is not a SE triode design but a pentode design and it’s seriously been hard for me to replicate the seductive nature of that little amp. The drawback is that I now have a much larger listening room and I find myself pushing the volume to clipping levels on some tracks I like to listen too with higher volume levels. Hell, if I was still had my previous listening room I could easily live with system 1 forever. I guess after all the comments what I am looking for is something with a wide and deep soundstage (similar to my little Inspire SEP) that I can push the volume level up without clipping. Yes, Double Impacts are 4 ohm.Great info here guys. Thanks much!
An issue with First Watt amplifiers is they're intended for audiophiles who know what they want/need already. They all sound different because (mostly) each model has different input and output impedance, and feedback. Several are current source amplifiers, not applicable to your speakers.
I don't really agree with some of the generalizations here, but I understand what you're saying. Each First Watt amp is unique. Some models, particularly the F4, require much more careful system matching electrically. Other models, like the F5 and F7 don't require as much "effort" as long as they have enough power for your speakers / room / output preferences. Nelson will simply suggest you give it a try and see for yourself. I think that's something we can all generally agree on, if one has the means to do so.
a single stereo amp at 24 w/ch which has been quite sufficient with all of my speakers (82 - 88 db efficiency), or as 75 w/ch monoblocks, or vertical biamp at 50 w/ch.
I heard a pair as a single, bridged monobloks, and using one channel of each amp. That last the best (relatively efficient, and easy to drive, speakers).dave
