Looking for tonearm inspiration

Denon DA-301 (a better choice for mc cartridges than the DA-401).

DA-301 is easy to find while the DA-401 is very rare.

You’re right, the DA-401 is ideal for mid or high compliance MM/MI, some MC cartridges also can be used as you can see on this Denon flyer. This is the arm with special headshell made by Denon (conventional headshells are not compatible).

I’m currently using my DA-401 with Joseph Grado XTZ (MI) cartridge.

You collect tonearms?  And you swap them out to play?  Just curious.

Not sure if you asked me, but when I bought modern high end tonearm (Reed 3p "12 inch) I start searching for vintage classics (tonearms and cartridges). Since tonearm/cartridge combination is critical I was looking for turntable that can give me the an opportunity to swap tonearms. Ended up with two Luxman PD-444 (4 tonearms in use, very easy to adjust, swap ... whatever... with 3-4 different type of metal arm bases provided by Luxman for this turntable).  

SME V or IV are ''obvious'' partners  for SME 20 TT. The postfix
12 may mean 12'' tonerarm. This would mean that the TT is
designed with those arms in mind. The seller sold them as
separates  to get higher price

Dear @chilli42 : Wit your XV-1s the Kuzma 4-point, Triplanar or the SME V are good match and very good tonearms.

Btw, Sutherland is a really good electronics designer and very good with phono stages.

Regards and enjoy the MUSIC NOT DISTORTIONS,

The Triplanar is one of the most adjustable tonearms made. Its bearings are several grades harder than those used in the SME arms. So it has very low 'sticktion' as well.

I operate a small LP mastering operation; the Triplanar is the only arm I've heard so far that gets everything right. Works fine with the Dynavectors too.

I agree with Raul & Atmosphere above

The Triplanar you will need to check the arm clears the suspension tower right hand back corner.

SME V is a natural partner and is excellent with the Dynavector

I have recently installed a Kuzma 4point and was very impressed with both a VDH Colibri & Kuzma CAR50 - this easily surpassed the same cartridge with Morch DP8 & Helius on the same TT.

I think the new Kuzma 4Point9 would be a perfect match for your TT/Cartridge - the original 4Point wont fit. The 4Point9 is a nine inch arm as is the SME V.

I would not touch a vintage arm, although there are some excellent vintage arms there is always a risk of worn bearings, corroded wiring etc.

The FR64S ( I have a couple ) has robust bearings.
The Technics EPA100 is an excellent arm, but I would not buy one unless I was prepared to upgrade the ruby bearings ( they are brittle and easily damaged ) with either new ones or silicon nitride for better performance.

In a nutshell here is my shortlist for your TT/Cartridge

SME V
Triplanar
Kuzma 4Point9
Graham Phantom

I would personally go with a new Kuzma 4Point9 or Triplanar.
If you go for a second hand Triplanar, get it serviced before you mount it.
Your turntable deserves the best arm you can afford.
