I own the Triode Pre-amp, their CD player, and the Triode DAC and love them all.
The tube pre-amp TRX-1 is a no-brainer, with my pass aleph 3 its magical. Its got good reviews on Absolute sound too. I think you should definitely get their pre-amp.
I am also trying to decide if I should get their phono pre-amp, but am not sure what the retail price for this product is, since its relatively unknown.
I had done a shootout with Triode DAC vs Benchmark vs NAD M51, and I liked Triode the best.
But of the 3 triode product I own, have to say the pre-amp is the best. It even has graphic equalizers which in the audiophile land a big no-no, but some records or rooms really need help. This graphic equalizer is by-passable too, so if you think it might degrade your sound, you can bypass it.
The multitude of inputs and outputs on this Pre-amp and a great anodized aluminium remote, makes this pre-amp my favorite component.
I only wish this equipment was dual-voltage, since I often travel outside the USA for months at a time.
Hope that helps, feel free to message me , if you need more details.
