We have been providing excellent headphone driver circuits in all our preamps for years now. However we never get any feedback about them from our clients.
Any user out there that cares to comment about them herein?
On the few occasions I have used them, they seem to be outstanding - clear, no noise, great definition, and drive any headphones I have with no apparent issues. Just what I have come to expect from any of your products.
Having said that, I am not a big headphone user, and most of my listening with headphones is with portable or away-from-home situations, not using my Insight+ preamp. At home, I generally use my regular system. I would imagine that most users are in the same boat, it's great to have the output when it's needed, but not a primary function and I just haven't used mine that much, essentially only for testing various headphones, and some trivial uses (like driving a short-range FM transmitters so I can listen to TV audio on my kitchen radio).
Also, you set the bar very high - when you get something from one of the flakey "audio salon" manufacturers, you really have no idea what to expect, and if it works well (and works for more than a few weeks...), you are generally a bit surprised. Get something from you, and everybody knows it will work, it will run properly nearly forever, and perform essentially perfectly. It's no surprise, that's why we come to you for it - no screwing around, just get something that works and use it, rather than being "equipment hounds" swapping stuff in and out every week as it blows up or you get tired of the "special voicing" or whatever bullsh*t thing the others do.
In a way, you are victim of your own success - the equipment is nearly perfect and your typical client picks you because they know that. So when it is, it doesn't necessarily draw comment.
