Dennis Had Inspire PSE 300B WOW!!!

Hi All... Yesterday I received my Dennis Had Inspire PSE 300B. My wife and I spent the evening last night listening and "we" really like it which surprised me since over the years I have compared numerous amps to my trusty Coincident 300B monoblocks and all have... until now... come up substantially short of the Coincidents. Now this puts me in a difficult position as my wife has had quite a lot of medical testing lately and with the associated financial pressures, I had intended to take a quick listen to the PSE 300B to satisfy mu curiosity then pass along and recover the costs to address the medical bills. Now, clearly that is not going to happen and the Coincidents will be listed for sale over the weekend.

By the way thanks Dennis, You Da Man!

My system (photos attached) is as follows:
Power - Shunyata Denali
Streamer - Innuos Mini Mk3 w/ PSU
Dac - Holo May-KTE
Pre - Sachs Custom Line
Amp1 - *** Dennis Had Inspire PSE 300B *** (horns)
Amp2 - Crown XLS 1500 (base drivers)
Horns - BD-Design Orphean w/ Celestion Axi-2050 drivers 220Hz-20KHz
Base - BD-Design Compact Reference
Sub - SVS 16-Ultra

Hi John... The Coincidents are the MK-II version upgraded with Jupiter Premium Copper Foil caps.  I did an A/B with the Mk-III version a year ago and frankly liked the MK-II w/ Jupiters better.  As for 300B tubes I have Western Electric, PSvane, etc. but the WEs are easily the best.  As for the other tubes I have a bunch of NOS 5U4 ect.  I'm actually on vacation this week and next but if you have interest in the amps let me know as I'm going to list as soon as I get back.

Som for Dennis's PSE 300B it does run hot.  Personally I think the chassis could be made a bit larger to enable better cooling.  But with four 300Bs and a number of large resisters needed for tube not transformer coupling I guess hot is the logical outcome.

Best regards,

Mark

Hi @tinear123 ,

What is an input and driver tubes in Dennis's PSE 300B?

Which rectifier and voltage stabilizers does it use? Is voltage stabilizers used for driver or input tube?

@jonnycopy

i can check in a couple weeks when I return from the Caribbean.  What I can tell you is no matter the heat the PSE 300B is staying in the system.  It’s that good.

Hi @tinear123,

I am a DIY person. So for me is very interesting to know how this great amplifier is built.

Can you give me some more information? What is the input and the driver tubes are used?

Regards,

Alex
