Re: my comment about the pot mod on the miniwatt, I have just seen a comment by someone that carried out this mod and they said that it further improved the sound quite a lot. Of course anyone who has a preamp could hook it up and use the volume control of the pre to bypass their APPJ's volume pot to see what effect this has. I haven't got a preamp but if anyone has it would be interesting to see what happens to the already fantastic sound! The only drawback would be that you are adding in another stage to the system which might adversely affect it soundwise. A review on tnt-audio said about using a pre on the main system...."there is a slight trade-off inserting another stage but I would say that it is worth a very slight loss of transparency for the extra 'weight' and scale that is gained." On the second smaller system they said..... "Now things were getting really serious. There was a real kick to the bass and it sounded deep too (deeper than the claimed response of 30Hz to 20kHz within 1 db). The sound was ' fuller' and that lean sound on some tracks was gone too. The speed which was already good got even better...." I've already said that I don't need a pre on the modded amp as the mods have increased the weight of the sound output anyway. BTW does anyone know if the APPJ uses negative feedback, because if it doesn't that could explain the clarity of this amp. Edit: Re: my suggestion to try using an active volume controller, ie a preamp to see what the effects on sound are by bypassing the pot on the APPJ, the other way might be to try a passive volume controller which would not introduce any further gain stage and so should be sonically purer. However I don't think I will explore this any further because although it would bypass the APPJ's pot, it could just as easily degrade SQ as improve it because of all the additional factors that need to be taken into consideration. As usual nothing is easy!
