I got a little side tracked with this thread, I'm back into the 300b theme .
I did not share, that on Sunday 25-06, I was able to attend a demo' of a 'new to me' system, which has Klipsch Jubilees as the resident speaker.
The resident system in use was quite special.
Following the Lunch recess, a friends P-P 300b Power Amp' was put to use.
The 300b is a late 90's model of which Tim De Paravicini has an input to the design. This Amp is now overhauled and a few circuit tweaks are carried out.
The system owners reaction to this Amp' was immediate, the Cheshire Cat Grin lasted for many tracks.
All attendees were thoroughly impressed by the way this Amp' interfaced in this system and it really shone out for its attractive traits.
That is not the whole story, the systems pre-amp was swapped out for a Bread Board mounted, part completed pre-amp build.
This addition of the New Pre-Amp had a substantial impact in conjunction with the 300b.
My take is that the design of the 300b in this Thread, has another 25ish Years (50 Years Combined) of experiences of Two Amp Designers, put to use, to help create this latest design.
I would get great pleasure from receiving a demo' of these mono's, to see where there are sonic traits that stand out as being more of a attraction and very much wanted to be kept.
