Favorite Tube Combinations

hi anacrusis:

this hobby is very subjective. therefore, tube a, with tube b and tube c, may be considered synergistic to one audiophile , but not to another.

i don't think there is any synergy between tube manufacturers other than reflect personal taste, which varies among serious listeners.

there is no universal synergy which would be accepted by all, because, practically speaking synergy is a highly ideosyncratic term, aurally speaking.

Agree with Mr Tennis. You are also rolling tubes with different gain factors which at first may give the impression of a dramtic change, but after time passes, that change may not sound as appealing, in fact you may even return to your original configuration because it offered something appealing that's just missing with the new configuration. Tube rolling to different brands is one thing, but to roll out to a differnt type completely is a whole different ballgame. I think that manufacturers do in fact employ complimentary tubes in their individual units. However, your idea begs the question, what do you do when two or three different tubes are excellent compliments with each other, but your piece of equipment can not use them in combination?? Are you suggesting that manufacturers build their equipment with circuitry to accept whichever tube you might have a fancy for trying, which would be very interesting, if it were possible!

This is pretty much exactly what I was responding. It's all rather subjective anyway...one mans ideal combination is another's one-tube-short of a circus. Sure, there's bound to be some general consensus in users, but if you don't fall under that preference it's obviously not a guideline for you to follow. There is no right or wrong.

I use a front end component, the Modwright Transporter, which is VERY versatile to tube choice, and VERY sensitive to tube rolling (changes make a profound difference). Dan (Wright) deliberately designed the analog output circuit to be very versatile in this respect and is a tube-roller's dream in terms of shaping the sound to how you like it. The Audiocircle thread on this subject is currently 53 pages and is a testament to how great an effect tubes can have on a front-end output circuit. The most recent development has been Octal adapters to allow use of other tubes like the 6SN7 in the 8-pin output tube position (the adapters are made available by Wayne at the Boulder Cable Company). I can tell you from my own experience with this impressive front end that just changing the rectifier tube has a profound effect on the sound (5ar4, 5u4g, GZ32, GZ37, etc.). As I indicated in my previous post, I find the closer the tube is to the front end, the more effect it will likely have...changing the rectifier in the MW Transporter has a far more profound effect than changing a rectifier in any tube-rectified amp I've owned.

Regards Mrtennis and all,

Tube rolling is not only about chasing some ideal, it's about discovery. If you accept the idea of there being any value to subject evaluations of individual components then it's only obvious that one component's characteristics can compliment another. Tubes are components with individual characteristics! I can recommend that a Tung Sol 6SL7 compliments a KEN RAD VT-321 and that it sounds good to me and that you should give it a try. I have most of the usual suspect 6SN7s and keep them so that I may change with my mood, with the recording and to achieve a particular spin on the music. Subjective?, yes of course it is.

As I review the previous posts, I would agree that context is essential and that suggestions of tube combinations within a given device would be of most value to the listener.

By the way, the Moscode 401HR and the new 402Au can use quite a variety of driver tubes and will allow as Cyclonicman suggests, to a degree, an opportunity to mix and match not just manufacturers but actual tube types. One of the best pieces of equipment I have ever owned and wish I'd never sold was the 300. Anyone have a second hand 401HR for sale? Only $4 per ad +%.
