while I'm not an owner of either but a friend of mine uses a Decca cart with a Croft phonostage to a great result.
I know that Glenn Croft uses Decca as his reference cart. Croft makes MM phono only btw.
What the Decca/London's need is not much gain (40dB is plenty) and lots of headroom. Their 5mV output is way too hot for lots of phono stages.
For solid state, the Liberty B2B-1 has both, John Atkinson finding it's overload margin about as high as he has ever measured. It retails for $1800 I believe.
For tube, the discontinued Herron VTPH-1mm is a great choice, providing 42-44dB gain (depending on tubes used) and pretty good headroom. Give Keith a call, as he sometimes has trade-ins available. You should be able to get one for $1500. The improved VTPH-2 will cost you more.
For the best performance from the Super Gold, you want to load the cartridge at 15k to 22k resistance, and 220pF of capacitance. The RB300 works pretty well with the cartridge, although an arm with a little higher mass and damping is preferable.
UK reviewer Ken Kessler of Hi-Fi News is a longtime Decca devotee, and has praised Glenn Croft many times, including his phono designs for use with Deccas/Londons. And Croft, being intimately familiar with the cartridges, may have his own preferences for loading them with resistance and capacitance.
Hi bdp24 , i was curious regarding the below in your post
For the best performance from the Super Gold, you want to load the cartridge at 15k to 22k resistance, and 220pF of capacitance.How can this be done for MM Phonos which i believe are internally loaded at 47K. does this involve some bit of DIY ?
I have a much older decca hence the interest !
I run a Decca FFSS MkIV C4E (rebuilt by John Wright) and Garrott Brothers Gold (retipped by JW). I have been using Deccas since the late 70s. I now use a TRON Seven Reference phono stage, which was built specially for my Decca. Of course, this is way out of your budget. However, I have also tried the budget TRON Convergence tube phono stage (GBP900 = USD1300) with my Deccas. It gets maybe 90% of the SQ of my Seven Reference for a mere fraction of the cost. Graham Tricker builds his units to order, and so you can specify cartridge loading etc at the time of order.
Over the summer I built a K&K Audio "Trio" for one of Kevin's customers and was very impressed by its performance. It faired very well in comparison to Kevin's all out assault on the SOTA, the Sonus Veritas Venice, a fully balanced differential, transformer coupled unit reviewed here: http://http//www.positive-feedback.com/Issue59/sonus.htm
The Trio's sins were sins of omission, not commission (added colorations). I believe an assembled MM version can be had for ~$1.5K. The circuit board is arranged so different loading resistors can be easily inserted. The input capacitance of the input tube and the capacitance of your tonearm wiring should put you in the 220pF ballpark.
If you can get a Herron VTPH-1 for $1500, nothing new or used in that price range will come anywhere close. If you pick up a MC unit, Keith Herron will probably convert it to the proper gain as well as put in the latest mods. Herron might even have a VTPH-1 taken as a trade that might be available. The only way to be sure is to call. In any case, Keith is always good for helpful conversation.
I got my VTPH-1mm directly from Keith. He had taken in a -1mc in trade on a VTPH-2, and offered to convert it to a -1mm for me. I told Keith I was using it with a London cartridge, and wanted as little gain and as much overhead as the amp was capable of. He put in two 12AX7’s and two 12AT7’s to lower the gain a couple of dB (that also provides a little more headroom in the circuit), and installed 15k resistance and 220pF capacitance at my request. He also sent along another pair of the tubes providing 2dB more gain. Whatta guy!
I got the VTPH-1mm before I heard of the K&K, but checked it out once I had. It looks real good, and if I hadn’t gotten the Herron I would have gone for a K&K. Definitely worth looking into. The TRON Convergence I investigated as well, but couldn’t get as much a "feel" for from the website. The fact that topoxforddoc (see above) has the good taste and refined sensibilities :-) of a long-time Decca devotee, and highly recommends the TRON, makes it a must-check-out imo.
No matter what phono amp you get, with your Super Gold you are getting the most dynamic, immediate, "live" sound from your LP’s as is currently possible! Is your SG mounted on a Deccapod? If not, John Wright will do it to yours if you send it to him. I ordered my London SG with the Pod already installed, and it is a HUGE improvement over the old Decca top plate and mounting system.
