Review: Tube Research Labs M-225 mono blocks Amplifier
I am glad that you have also enjoyed the TRL M225 immensely. I have been a proud owner myself also for 3+ years. I have also owned a few top brands before, and heard DartZeel, Boulder, Goldmund, ASR battery, Gryphon to name a few at friend's whose... 
TRL ST225 - Goodness anyone else own this amp
Terryn: I think the battery PS takes it up to a different league. I won't hesitate if I could do it over again. The batteries used are the seal, deep-cycled ones. Since my mono's are customized units, they come in as a 4-piece configuration. Howev...

FYI, for KAS, the manufacture recommendation is 30A per mono. 
krell audio standard
Both KAS and KAS2 abilities to drive 1ohm or perhaps lower are still matched only by very few amps. They are pure class A hence runs very warm as space heaters, yet have that musical hearty class A sound. Being a KAS2 owner, I would STRONGLY recom... 
TRL ST225 - Goodness anyone else own this amp

TRL ST225 - Goodness anyone else own this amp
Just pulled a past email from Paul about never using fuses in his own designs, but circuit-breaker switches for the reason yielding much better sound. FYI, here is the spec I have collected about the amp:Input Impedance: 68kohms Input Sensitivity:... 
TRL ST225 - Goodness anyone else own this amp
Based upon my recollection of conversations with Paul, I don't think the amps have fuses in them, but circuit breaker switch only. Besides the full spectrum tonal balance Bill experienced, one among other things that impressed me is the "density" ...

TRL ST225 - Goodness anyone else own this amp
I am glad to hear that you discover this special gem. I have an opportunity to hear ST225 at a friend's in Philly driving a 3-way with a pair of 15" woofer. With Paul's expertise in design and manufacturing top tier tube gears, I think he manages ...

Battery powered amps
I have been the owner of TRL SS mono amps with battery power, M250 (250W) and M500(500W) for over a year. The huge ~200 lb battery chassis ensures the instant, ample, and sufficient current can be supplied on demand, especially while playing back ...

Esotar T-330D Tweeter
About two or three years ago, I called Dynaudio to get a quote on a pair for replacement, they quoted me $1200 a pair. I think $850 a pair is good in comparison. 
Review: Cullin Circuits mods to PS Audio P1000 Power Plant Tweak
