Supratek or Rogue?

I own a Chenin (Chardonnay plus phono) which I have extensively modded. These preamps are easy to mod due to their point to point wiring. I converted to single 2C22 tubes to replace the series 6SN7s, changed the anode load from resistor to cascoded CCS, changed the cathode bias from bypassed resistor to Schottky diodes, swapped the output caps to 1uF Duelund Cast, swapped the output transformers to Lundahl LL1674, changed the electrolytics in the power supply to Solen PP caps, and bypassed the mute and transformer loading switches. I use a Mullard GZ33 rectifier and Sovtek KT66 regulators.

The preamp sounds awesome now - fast, clear, dynamic, and very musical. I wouldn't swap it for any other preamp I have ever heard.

My point is that as good as it sounded stock, you can take it to a much higher level with some mods. So I was able to start off at a relatively low entry price and progressively move it up the preamp food chain with just some parts and a soldering iron. If you are in the NJ area, PM me and you can stop by for a listen.

The Supratek is a classic.There are a couple of talented individuals in the US who can diagnose and repair if the need arises,so I wouldn't let service concerns impact your decision.

You are asking a question that may be answered in a way not serving your best interest.
There are many pre amps out there.
Mark at rogue engineered the M180s to work well with the Rogue 99 pre amp.
You may find many good looking pre amps winning over the harts of the well intended some making the choice on looks first.
Most are eager to recommend their favorite pre amp in their system to you.
But I would ask how many have actully heard the Rogue 180s and Abed a Rogue 99 up against pre amp b in that system?
and then what happened.

Perhaps Audioconnection should disclose that they are a Rogue dealer when answering posts?

Audioconnection makes a good point about in house synergy between preamps and power amplifiers. However, I've used a Supratek preamp with Supratek mono blocks and while the sound was good, it wasn't anywhere near the level I've achieved with my current Supratek/Yamamoto combination. Just food for thought.
