Mark OBrien Interview


Q & A with Mark O’Brien of Rogue Audio:

Q: What first attracted you to tube based designs?

* Audio has always been something of a passion for me and I have been designing audio equipment since I was a teenager. I really wanted a tube preamp because I had heard how much better than solid sate they sounded so I went out and bought a relatively inexpensive one. After trying to convince myself that it sounded great, I realized that it actually sounded pretty bad. That set me going on trying to design one myself and after designing some pretty bad ones I finally hit on some designs that sounded pretty good. Further refinement eventually got me to the prototype for Rogue Audio's first preamp the Sixty-Six.

Q: How have you managed to offer very fairly priced, superbly built products manufactured in the States?

* For the most part we just don't charge as much as our competition. A couple of reasons why we are able to do this is by keeping our overhead and operating costs to a minimum and through careful supply-line management. We have long term volume arrangements with our suppliers to provide us excellent parts at very reasonable prices. Since we have worked with them for years and years they are comfortable with building say, five hundred custom transformers and letting us pull them in as we need them.

Q: Have you ever thought about developing a source component?

*Yes, we have some DAC designs we are working on but we are still in the very preliminary stages.

Q: Lastly, vinyl or digital?

*Until recently I would have said that I had finally succumbed to the convenience of digital - it has really gotten that good. That said, I have spent most of  the last year developing our soon-to-be-released Ares phono section and as a result spent a great deal of time listening to records. After spending that "quality time" with my turntable I have to say that vinyl is still something special and somehow remains a bit more engaging to me than digital.
