I must hear some of his gear sometime. I know some if it runs red hot which I am not a fan at all with tubes (fine with red hot class a solid state) but must admit to reading more than a few times that he is one of most inventive, creative and brilliant designers of all time. A true savant.
I think if I ever do try a tube preamp again it will be tranny coupled design or with some JFets in there.
People speak of the modern sound of tube preamps in some cases in a negative way. I use to always be a fan of the classic CJ sound myself for years but even they have moved much more to the middle.
After my last experience with a tube preamp with my current system it is easy to why ARC and now CJ and most others have gone the way they have hence the modern tube sound. At the same time the solid state sound is much more like tubes which is fantastic. There are some things tubes do that solid state can probably never do and probably not vise versa.The problem here being to better excellent solid state sound via tubes cost much more money. I think SS can get you 90% there / maybe a bit higher and to top that with tubes to get that last 7% - 10% puts you in the $20k to $30k preamps where SS can get you 90% for around $10k and used $5kish. The best bang for buck premium sound IMO is the SS pre but of course that is just IMO.
The more transparent and neutral our systems become the closer we get. The closer we get the more transparent and neutral every addition must be. The leeway or wiggle room window either way is so much smaller.
Any deviation from transparency and neutrality as you get closer seems to push you further away so transparency and neutrality that were once more preference are now mandatory and no longer optional.
It is no longer about voicing or preference anymore. It is now purely about simple second grade mathematics. It is either addition or subtracting. I don't mean this in the most strictest sense but you get where I am going. This makes it both easier and harder. Easier because it is simple from the standpoint it either sounds better or worst. Harder because you must find the square peg for the square whole and I looked and don't list that on the package. We must purchase try and either keep or flip. Now thankfully there is a place such as this with like minded, intelligent people that understand clearly these things where ideas can be shared , debated and pushed forward. For that I am grateful.
With tubes once you get in deep the Pay to play goes up a whole bunch :)
