Review: Tube Research Labs Samson monoblock amps Amplifier


Category: Amplifiers

This is a review of the latest solid state, mono-block amps from Tube Research Labs (TRL). They are named Samson by the builder Mr. Paul Weitzel of TRL.

Please to go my system link below to better understand my room set-up and ancillary equipment. This will help you better understand the full context of my review.

I also encourage you to look at the long list of amplifiers I have owned or listened to extensively in my home system over the last 5 or so years. I have been very active on Audiogon as demonstrated by my feedback and long list of amplifiers. I have been fortunate as I have sold gear for audio friends who had wonderful gear. This has enabled me to play with some fantastic gear over the years.

Finally, I listen to female vocalists, jazz, a little classical, piano and guitar instrumentals, contemporary Christian and alternate adult music. Some of my favorite artists include Van Morrison, Beth Orton, Sarah Groves, Aimee Mann and Rickie Lee Jones. I like to listen with the lights off and often with my eyes closed. Music is the way I relax and get away from all that fills my head in a given day.

I am not a technical person and will do my best to tell you a little about these amps. Please call TRL if you have questions as I can report on my experience with these amps only.

-Paul states they put out close to 300 watts per amp.
-Mine are single ended, but think Paul can build yours as needed.
-No fuses as TRL employees a circuit breaker as the on/off switch.
-They always run cool no matter how long or hard I drive them.
-Very quiet – no real mechanical or chassis noise.
-See my system pictures for cosmetics.
-$5500 for the pair
-Shipped in a custom made wood crate very well padded and secure.

My experience with the twin Samson amps
_______________________________________

Let me say upfront that I do enjoy trying new gear and hearing the differences between components in my system. This was never a hassle to me, but fun. This has now changed as the TRL amps make music in a way that no other component has conveyed. This was true of the TRL S225 integrated amp and now even more so with the new Samson amps.

We all try gear and notice that this one sounds more transparent and that one has more midrange warmth and on and on…….. They do all sound a little different and sometimes greatly different. Some certainly outperformed others. I even recall saying one “killed” another with its overall performance. However, looking back they all had some limitations and in one sense they all sounded alike – like reproduced music. Here is where I begin trying to share my experience with these Samson amps in relation to all others I have enjoyed.

For me the Samson amps paired with the Dude tube preamp (TRL) broke through a sound barrier I truly thought was not even possible. This is why I am no longer compelled to try another amp flavor.

So, in what ways do these amps break new ground? Ok, this is a time where those standard Aphile descriptions just don’t reach far enough. The Samson amps are the standard for neutrality, imaging, bass authority, transparency, tonality, extension at the frequency extremes and so many other attributes based on my experience. Fellow music lovers let’s move beyond the elementary and onto the real deal.

Musical instruments and voices now sound live and not bound by the constraints of hardware. My words will fall short of my experience here as this really must be heard to be fully understood. The piano is now released in my music room. It sounds so live and un-reproduced. It sounds real and so right. The attack of the keys is alive and full of energy. The body of the instrument is palpable. Every key stroke is discernable and presented with utter clarity.

Kick drums come alive with impact, energy and realism I have only heard at the best live concerts. Voices flow with a sense of space and dimension that literally places the artist before you.

Even my most complicated jazz recordings come alive with discernable instrumental lines that were previously completely lost or blurred. Background notes, vocals and phantom sounds now BECOME part of the music. You must hear this first hand!

Does it sound like a tube or SS amp? My answer is very simple. It sounds like live music. I don’t even think about that notion with these amps. It seems so off point now. Please keep in mind I mate these amps with a nice tube preamp (review coming).

Never do these amps even hint of being compressed or strained in my system. My 8 ohm speakers are 90db efficient and I play music as loud as 102 db at rare –very rare times. The music grows in size as the volume is turned up. It never shouts at you screaming “I’m very loud”. Rather, music swells and its impact is awesome to experience. The other powerhouse amps I have owned are boys in this regard. The Samson amps are men. They are always in complete control adding to the live musical experience.

Yes, you will hear music previously lost in your system. Yes, there is air and space around each instrument as music floats from the blackest background imaginable. The Samson amps are state of the art in this area. They are pure magic to experience. I hear a whole new dimension to the music in my room. I can close my eyes and get so lost in the music. I feel and sense the piano behind the sax player over to the left and Van the Man just turned his head in the studio!

I will end by saying the Samson amps delivered music as I have never experienced in my dedicated room. They broke though a performance ceiling I thought all amps had in common.

I’m without a main system for the moment, so no amp/pre to speak of. I’m using the 8001 in a small second rig with a Dussun integrated amp, Jena Labs cabling/conditioning, and Definitive Technology speakers. When I get a main setup going, it’s probably going to be built around a high-quality integrated of some sort, likely solid state.
Hooper - If a solid state integrated amp is what you're after, add the TRL ST-225 integrated to your list.
Hi Bill,

You finally found the end of the road and hopped off the merry-go-round for good ?

Kidding aside, I know how difficult it is to describe an experience that's different from all the rest.

You expressed that difference quite effectively to me on the phone and by your previous posts.

It was not hard for me to understand, because this is what I was looking for all along
(the audible illusion without listening to the equipment) ?

TRL's extensive R&D experience and track record for being nothing less than the best puts me in a no-brainer decision maker, the Samsons will be in my system when things pick up here, that's for sure.

Paul and Brian kick butt, no doubt.

Great review well done, Merry Christmas and Happy Holidays !
In fits and bursts I've been formulating a review for my Samson Pair. I've read your review several times Bill and wonder if I can add anything substantive.

Everything said here is absolutely true. I've had multiple commercial amps and various iterations of Musical Concepts modded Haflers -- the final quite radical and excellent. The Samson is not simply on another level, it is in another existence. This may sound excessively purple, but it is true.

I'm compelled to add something about the First Watt, a zone critical to my listening habits.

I frequently listen at very low late night levels (sleeping wife) and the Samson retains its qualities all the way down to virtual inaudibility. There is no shrinkage of the soundstage or sense that the stage is receding. Even the incredible bass extension and weight are somehow preserved.

All the audiophile requisites are there and become secondary. I am a severe amp cynic and these things are simply unbelievable. My closest contender is a Clayton S-40.
This Clayton is outstanding, one in which I thought could not be bettered. It has been -- quite mercilessly.

Job well done with this review Bill. Every Audiophile owes it to himself to somehow audition this amplifier.

I'm reminded of Peter Moncrief's commentary years ago regarding the magical aynergy of the Futterman OTL-3 and Quad marriage. A rare and singular sound all should experience at least once. And so it is with these monoblocks, my final amplifier purchase.

Congratulations on your purchase Dave. Glad to hear you are happy with the Samson's and TRL sound.

The low level listening aspect of the TRL sound is truly amazing. I found myself in the same situation as you, but instead of a wife it was neighbors who could very easily hear music through the walls of the apartment, even at less than modest volume levels. TRL solved that problem for me.
