Tonearm adjustments on the fly


I've looked in the archives, but as yet I have yet to find a devoted thread on this topic. I was wondering which tonearms allow for easy adjustments of VTA, SRA, azimuth, and such on the fly, i.e. without having to go through a lot of effort to make changes, like unscrewing a tonearm from the mount in order to raise the tonearm, etc. I know that Reed tonearms allow for this, but what other ones do?

Thanks mijostyn.
I quite agree a degree or two of VTA cannot be heard.
I was just trying to be nice and pander to Miller and others who say it can, but not in blind tests.
Fremer measures his with a microscope although his ears are aging now.
Ho hum.
I use a USB microscope also clearthinker but mostly to make sure the stylus is not way out of spec. The worse I've seen since I started using the microscope, which is a PITA by the way, was an AT cartridge. It was at 3 degrees in the wrong direction or 87 degrees. That is tracking the record.  I sent it back. The Soundsmith and Clearaudio cartridges have been very accurate and just setting the arm parallel to the record would be fine.

I have Pure Vinyl which is a Program I use to record records to the computer. It has digital RIAA correction which I have not had a chance to try because you need a phono stage that can bypass it's correction circuit. Anyway, I have recorded samples of the same record at various angles + - 2 degrees and you can AB them. I can not hear a difference on electrostatic speakers. Now we will hear that "digitizing the record changes it so you can't hear the difference" or "Your hearing probably sucks." I agree. You can't trust anyone's hearing. I do not trust my own which is why I like running these silly experiments. Digitizing the music at 24/192 is invisible. It sounds just like a turntable, warts and all.
In my opinion TriPlanar is ugly industrial design while the Reed 3p is pretty elegant (remind me of DaVinci tonearm a bit).
It is, but also features the hardest metal bearings used in any tonearm made worldwide. This allows the bearings to be adjusted so there is zero play, something you can't do with a jeweled bearing (lest it crack). So it has the least chatter and sticktion (I made that word up but you know what I mean) of any arm made. So while it might not win any beauty contests, it does get the job done. Of any arm I've tried and used it comes the closest to sounding like my master tapes.
Dear Chakster, I would not disagree for a moment that the Reed 3P is more beautiful than the Triplanar.  What's more, you can order one in different wood and metal finishes to suit your taste, like a car.  In my opinion, the Reed toneams are sonically competitive as well.  My only point was to challenge the notion that the Reed 3Ps azimuth adjuster was "the best".  It's very good, I'm sure, and does the job adequately.  Comparing my Reed 2A to my own Triplanar, built by Herb Papier nearly 30 years ago, I would have to say that the quality of the adjuster on the TP, taken as a tool only, is a bit higher than the one on the 2A.  The TP adjuster has a better "feel" and allows for finer movements up and down.  Tri, the current maker of the TP, has improved the adjuster on current manufacture TPs even above mine.  By comparison, the 2A is a bit coarse feeling. The 3P may be a different animal for all I know.
Mike L, Do you know what prompted Durand to switch from wood arm wands, the use of wood for which were at the heart of the company philosophy once upon a time, to other materials?  I have heard the Talea, Talea2, and the Telos on a neighbor's system.  My too brief listening impressions suggested to me that the Telos was not much of a sonic upgrade on the Talea 2.  In fact, I might have preferred the latter.  The Talea 2 with a UNIverse cartridge was memorable.  (Same turntable, phono, amps, and speakers in both cases.)  Of course, the cartridge mating is key.
