Nice turntables. Attached picture is an absolute requirement.

I thought I gave up on vinyl years ago but then I inherited several hundred records in pristine condition. I could not resist finding out how much I could get out of the groves so got a little carried away. VPI Classic Signature with four wands. Each wand has a MC cart mounted and balanced so its very easy to change when desired. The Classic has "on the fly" height adjustment which also makes it easy and quick to adapt to different carts. Of equal importance to discover the potential of the format is the phono stage. In my case I use the Modwright PH-150 phono stage which also has "on the fly" adjustments for gain, loading and capacitance. Not sure the cost/performance ratio is justified but records do sound very good on my system. View attachment 370138View attachment 370139View attachment 370140View attachment 370141
The Classic series is a beautiful line of turntables. I can’t say how they measure, but they are well regarded sonically and wonderful to look at!

I looked at many options before I picked up the Classic Signature. There may be a few TTs out there with slightly better specifications at this price point, but I like the Classic because of its solid build, the ease of changing carts/wands with the uni-pivot and the fact it looks like the TTs I’m familiar with.

Solid build and looks are the reason I went with a Classic 1 a few years ago. Plus, ease of upgrade (I've added the HW40 feet, vta on-the-fly adjusment, Fatboy Gimbal, Phoenix Engineering RoadRunner/Eagle package).
 
Phoenix Engineering RoadRunner/Eagle package....
would be interesting to actually observe the impact of the eagle...
even, taking the usual precautions, with a classic app like turntable speed, particularly in w&f...

Unfortunately, I didn't save wow and flutter data from Dr. Feickert Adjust+ when I swapped cartridges a few months ago.
That said, speed (both 33.33 and 45) are rock solid using the Eagle/RR. I'd say +/- 0.005 to 0.006 rpm, which is within spec for the RR.

That’s how I got back into vinyl, too. Three turntable upgrades and three phono swaps later, I think I’m at the end of my upgrade path.

what is interesting is really the calculations of w&f....
(I imagine that will be good because i can obtaining without frequency regulation, a big weakness, a very correct 0.05% sigma2-0.03% rms on an old 19mk4 vpi, "the ancestor" , 30 years, belt, semi-suspended..)
the feickert had its limits because it depends on the test disks used..
certains free apps like what I pointed out offer a rather relevant w&f observation, in my case even at avg speed but without the test disk constraint
(but care was taken in its positioning of the phone, see on some decks is awkward, but this will not be the case with yours)
;-)
(observing the speed with only one point at each turn of the roadrunner is objectively a little clumsy... but the efforts in the eagle, small ""inverter- frequency converter hq "" , is interresting...failing to be in "dc" motor mode, this is what the old vpi lacks so that the speed does not accompany the shifts in the frequency of the mains current like all turnables using this ultra classic approach...)

Well, curiosity got the best of me and I tried the app you had mentioned above.
Not sure how accurate it is but I would say the measurements with the RR (tach, which provides the feedback) and w/o are essentially the same.

With Tach: speed +/- 0.80%, WOW (2 sigma) +/-0.12%, Wow (RMS) +/- 0.07%
W/o Tach: spped +/- 0.86%, WOW (2 sigma) +/-0.10%, Wow (RMS) +/- 0.06%

Single measurements only.

(leveling the plate and) precise centering of the phone on a flat pressure puck is essential ;-)

and to check with strobo etc and these figures are hardly acceptable...
in your case it may not work well...but in principle if the speed difference was not so huge, the values of w&f are normally rather correct by the principle of the calculations...... :confused:

(but I had come across scoutmasters2 etc at 0.09% sigma...probably lubrification story)
 
"attached picture is a an absolute requirement."

Denon DP-47F

You may not like it, but it's peak performance.
 
It's beautiful and fully auto too. Everything to like with this model.
Are these adjustments or there to make people ask questions?

balancing elements probably or more simply the bearings...(?) because it is not made for adjustment...

They are just to get weight or purely for show, i suspect. One of them fell off once, it's a small aluminum cylinder glued to the AT-AT looking plastic enclosure.

yes..or for aspect...:p

Nice thread, and interesting. @JP - your collection is amazing, you found so many of the top classics, wonderful to see :). I'd visit the museum :D!

Interesting to see so many Denons still in operation around the world too, they really made some excellent tables back in the days. My daily driver is a DP-57L (same as DP-62L) , shown a few times already in this thread. It has an excessively powerful motor, it will maintain "Lock" while carbon fibre brushing! Magnetic break, stops instantly. Dynamic Servo Tracer actually works, it reduces LF resonances as promised. Stability is excellent, in part, perhaps, due to the most impressive bearing. Doing the spin-down test, the DP-57L record is from 33 to full stop: 4 min. 31. sek. From 45 to full stop: 5 min. 45 sek. Great bearing ;)! Here's mine with original DL-301. Not ideal armwand for this cart, perhaps, but no problem. Sweet cartridge, like so many Denons from the golden days...

Here's my Thorens TD160 BC(ustom) MkII in DIY 30mm solid oak plinth with AT1100 tonearm & AT24 MM cart, a pair from the high compliance times, when beryllium still was in use. The AT1100 has since moved to a different platform, a Kenwood KD-550 where it currently sits, and fits better. As you can see, it's on the edge of the tonearm board. The AT24 has hand-wound coils, btw ;). AT24 was top MM performer from AudioTechnica, 1979. The AT1100 was actually made for this cart, so "perfect match", 10Hz res. f., according to the promo. The AT24 generator was later used in AT22 & 23, but was first used in AT 25, 1978, with integrated headshell. (In addition they used it in their later US "luxury" subsidiary Signet TK9, TK10 & TK100 carts.)

A classic combo, SME 3009 S2I and Technics SL-150, 1976. Here with above mentioned Signet TK-9. Love the platter dots! Simple and functional, still in daily use at a friends house now. Would have kept it if it wasn't for the Denon... (and lack of space).
