Dennis Had Inspire amps and preamps.


Recently acquired a lightly used LP27a and a SEP Firebottle HO amp after a recent dip into SET/SEP-dom.  I liked them enough to order a new LP3a preamp from the "auction site."  Hand-made in USA by an arguable hifi "legend" at, imo, comparably reasonable prices.

These pop up from time to time in various A-gon discussions.  I know there is an unwieldy and lengthy discussion on another site, but thought would try to open up a fresh one, here.

Curious about (good or bad) experiences, listening impressions, tube-rolling, mods/upgrades, speaker/gear pairings/synergies, etc.

Right now, I have the Firebottle with Omega 3 HOs, and am enjoying the result.  One immediate question would be what tubes can be used in the Firebottle and in the output tube in the LP27a.  I bought them used.  I have an inquiry to Mr. Had on that, but maybe others have first hand experience on what works well?  For example, the LP27a came with a 6sn7, but I've read that others have been able to use 6sl7 and even 6bx7 in that spot.

Thank you.

No clue about the preamp except that they’re well regarded, but I’ve been raving about the Fire Bottle HO amp ad nauseum since I bought it a couple of months ago…my fave tubes are the supplied new version Gold Lion KT88s with an Amperex 6SN7GTB (NOS USA version I like enough that I bought another one), with a serious looking Shuguang 274B rectifier (the amp came with a JJ 5Y3S that sounded fine, but the other rectifiers seem more suited to the 88s). I tried KT150s in the thing but the 88s sound better to me, and KT77s are just OK in my rig but others have had good sound from those. The new Gold Lion GZ34/U77 is a great sounding rectifier tube also but the 274B just looks so cool…you can hear the tube differences immediately with this amp, and it seems you can stick nearly anything in it and it handles it fine. I use 91db Silverline Prelude speakers with 2 REL subs….best sounding amp I’ve owned in over 5 decades of this stuff….amazing…and FUN.
I had no success with an Inspire Fire Bottle KT88 amp. I really wanted to love it, I even had Dennis custom make it in blue, to match the color of my Cary SLP-98 F1 preamp. Unfortunately, no matter what tubes I tried, and Dennis did send me many to try, I just couldn't get it to open up.
Always sounded closed in and congested, with rolled off highs and lows.

Speakers were Soliloquy 6.3i, which I thought would be a good match, since Dennis helped to design them. No dice.

It was a joy working with Mr Had though. It was a fun experience, and in the end, he had me send it back to him because he was sure it was damaged.
Upon receipt though he said there was nothing wrong with it, so he refunded my money. No harm, no foul.

If it works for you, enjoy it!!!
Wolf and John have such vastly different results with the same power amplifier. Either the speakers used account for this or Wolf has possibly a "later" or "improved" version of this amplifier.

Wolf is the Silverline Prelude a better match than your Sonist speaker with this Had amplifier? Best sounding amplifier you’ve had in 5 decades is quite a compliment, congratulations on obtaining this level of sonic bliss.
