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.

I’ve enjoyed using an older Inspire with 6550’s driving my Audio Note E/Spe HE speakers.  Very impressed with dynamic range and decay at low volume.  Gets a bit shouty if volume goes too high.  I’d like to try it with some cheap horns, maybe the Klipsch RP-600M’s.
