TRL ST225 - Goodness anyone else own this amp


I will soon be writing a review on this amp and wonder if any fellow Agoners own this gem. If so, please let us hear your comments on it. I am nothing short of amazed by it. I had to "downsize" and sold a tube monobloc amp and tubed preamp combo costing over $15,000 new. Both pieces were fine sounding and well regarded.

I ended up trading a set of speakers for a TRL ST225 integrated amp. I had never heard of this amp before and was not aware of Paul's work.

All I will say for now is this integrated amp bested my previous set-up and is the finest sound my speakers and room have provided.

I am a tube guy folks and this SS amp is still the finest amp I have ever heard. I put $5000 in the bank and have better sounding music. Now that is exciting!!!

They cost some $5500 new and mine was purchased/traded as used. It had just been updated by Paul and came direct to me once the upgrade was finished.

Happy in MN

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" of the sound "images" in the stage that the amp is capable of casting. I am lucky to hear some very good setups of a few top amps (i.e. Gryphon, Jadis, Goldmund, ASR, Halcro, DartZeel, Kondo, etc) at various friends' dwellings. Personally, my TRL amps have never disappointed. For people seeking truthful, distortion-free, grain-free reproduction of music, IMHO TRL amps should definitely be on the short audition list before purchased.
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: 1.1Vrms
THD: < 0.05%
Gain: 30db
Noise Floor: < -100db
Rail Voltage: +/- 76 VDC
Power: 225 watts
Power consumption: 600 watts
Your right Howard, it has been known for years now that fuses are not the way to go . Hopefully, someday the others will catch up.
Paul told me the gain on my amp was about 37db and input sensitivity .8V. I would have to agree with the gain number as most preamps I used with this amp could not get past 10 o'clock on the volume control before reaching my preferred listening level (about 90db or so). Only exceptions were the K&K Audio TVC and the TRL Pre-1.5.

On the power consumption I find the number interesting. I once had an Exact Power EP-15A. With this component as you plug gear into it the display tells you how much power consumption is being utlized. I plugged in my DAC and transport and the display read 30 watts. When I plugged in the amp I expected an increase along the lines of 500 watts or so, but the display increased to 45 watts. On occasion it would rise to 60 or 75 watts when I was playing music. I thought there might be something wrong with the EP-15A so I called tech support at Exact Power. They had me run a simple test. They asked me to get the power consumption rating for my TV and then plug it in to the EP-15A. Sure enough the display jumped up 150 watts, which was the correct power consumption rating.

I'd like to know the slew rate and damping factor of the amp. However, I've learned that Paul eschews specs when designing and relies on his ears much more.
I was listening to great music tonight and am so thankful for this amp. Natural is the word of the night. Music flowed so naturally and easy.

Every CD I play just gets my full attention.

I keep my amp on at all times and have not noticed a larger electricity bill? Can't be pulling that much juice from the wall? The amp is never even warm to the touch.

Paul did confirm the amp uses no fuses as they degrade sound.
