Dennis Had FIRE 300 B tube SET

   FWIT I run a Rogue RP-1 into an older Firebottle SEP feeding Zu Omens. Schiit Yiggy , Thorens TT and MF transport up front. I have about 15 pairs of power tubes and 6-7 rectifier tubes for the Inspire. The Rogue pairs well with the SEP. I have about 10 sets of various NOS 12AU7’s for the Rogue. I prefer Telefunkens as they really help the Rogue open up. I also run an upgraded power cord and isolation footers. The phono section in the Rogue is lacking and the headphone section sucks. I rotate a 50 wpc SS amp when I play vinyl. I have a Grado Prestige cartridge and it’s not a good match with the Rogue. I hope that can lend some insight to your 300b question. I’ve emailed a few times with Dennis and he’s given me solid advice. He’s about musical enjoyment at a modest price. Regards , Mike B.

I have a KT88 Fire Bottle, awesome little amp.  No preamp into Klipsch Forte’s @99 dB sensitive.  Superb soundstage and imagery.  Dead silent when no signal, you’re going to love the 300b with good speaker match. 

I see Quicksilver Audio mentioned here.  I stopped by their Website yesterday and it seems that Mike is now only manufacturing two lower powered pairs of monoblock amplifiers (The KT mono and Mid mono) and an integrated amplifier.  He still has a few different preamplifiers for sale  though and of course, his headphone  amplifier. 

I have Dennis's PSE-300B amp and love it.  I ordered on a whim to compare to my Coincident Frankenstein 300B monoblocks which have handily bested all comers over the last 7 years.  Well, the PSE crushed the Frankies in most areas over the course of a 4 week A/B period.  I ended up selling my long time Frankies and have not regretted for one minute since.

Interestingly, the downsizing of amps came about for multiple reasons as I understand it.  Mike was able to consolidate the former push pull Mono 60, 80, and Mono 120 amps into single amp to run all of the larger KT tubes ranging from KT66 to KT170s for higher power applications, yet with lower power now gives delicacy of lower power amp sound. Not sure how he pulled this off, but it works.

The Mid-Mono ("50% Triode" - Ultralinear) as he calls it, remains, essentially more optimized for EL34, KT77, yet can run up to KT120. Another point of consolidation.

And of course the neat little EL84 integrated and the headphone amp, and one Linestage.

As a former Inspire amp owner myself, I’ve been following along with folks who’ve added the Quicksilver Mid Mono amps into their collection with higher efficiency horns speakers. I’d love to put Dennis’ 2030 or CJ5 preamp in front of the new Quicksilver Mid Mono amps to see how that sounds. Good fun.
