Anyone using the Transistor Research LabsM 225's

In the photo of the Samson amps (should we assume these are the same as
M225?), I don't see any heat vents. Is this correct?

Do the amps run cool, warm or hot?

Bill,

Great looking system & room.

Tvad - the Samson is the same as the M225 and they run cool.

Tvad,

They are cool at all times. I keep them on 24/7 and even when run hard they stay cool to the touch.

They are now named Samson amps as Bob mentioned above.

I just finished a full review that should post soon.

Tvad,

They are cool at all times. I keep them on 24/7 and even when run hard they
stay cool to the touch.

Can anyone confirm the operation class of these amps (Class A, Class A/B or
Class D)?

The Samson (M225), and the D225 appear to have the earmarks of Class D
amps in that they run cool and have reasonably small unventilated
enclosures.

Ecruz mentions in his listing for a TRL D225: “...absolutely dead quiet, the
sound is effortless, neither warm nor cold, neither like tubes nor solid state,
just music".

This describes what I have heard in one or two Class D amps (particularly the
NuForce Ref9SE V2), and especially the description of lack of coloration
(neither warm nor cold) and sounding neither like tubes nor solid state.

I owned the Nuforce Ref 9 (not SE) amps and they were cold sounding. Forgot to mention those in my listing of other amps. Had them for a month, but I needed more body and texture then these were capable of. The Samson amps are not Class D, but A/B amps.

Also, a friend of mine owns the D225 amp and it is also wonderful, but the new Samson mono's are certainly better.
Paul and Brian have new learnings and thus the birth of Samson.

I can see why you would think Digital or Class D Grant.

They have far more scale, body, texture and dimension to them as compared to my past Nuforce experience.
