Tube Research Labs Solid State Designs


Has anybody heard Paul Weitzel's designs that would expand on the signature sound of his amplifiers

I'm very much interested in buying one of his amps but I have not heard it and going solely on what I hear

I can't seem to find any pictures anywhere
The TRL websight has not been updated in a while
Paul must be busy working on Medical breakthroughs

I also have a small listening room, smaller than yours in fact. One thing the TRL will afford you is the opportunity to listen at low volume while retaining excellent detail and musicality.
I have the Transistor Research Labs (TRL) D-225 solid state amp. I bought the first model and have not looked back. Extremely quiet and drives my Spendor 1/2e speakers effortlessly.

If you live in SoCal you're welcome to come by for a listen.

Also, just call Paul and talk to him about it, yes they are busy, but I always seem to get through and he is always very helpful, whether over the phone or email.
I am playing around with room treatment as well right now. I am also adjusting toe-in on my speakers and finding that makes a big difference in the soundstage and imaging. I do have a nasty bass reflection though that tends to throw the bass on the towards the other side of the soundstage. I guess a bass trap or plant behind the speakers might help this.

If you prefer natural sound and accurate reproduction you just nailed the D-225. I know we have spoken about this a lot recently but that sums it up right there. As Kurt said the value factor is very high and you would have to spend significantly more to achieve the same results with other equipment.
The D-225 is strictly class A and while it is rated at 225 watts it is closer to 300 watts. The D-225 sucks up about 600 watts for power consumption. I have mine plugged into a Running Springs Audio Haley which handles 1800 watts (15amp). I have other components plugged into it as well. No problems so far.
