Upgrading to an external Phonostages for my system


Here is my system...

Harman Karman HK990
VPI Scout turntable with a JMW-9 memorial arm and an Ortofon 2m bronze cartridge (mm)
Revels F52’s
SVS PB-NSD subwoofer.

Not schooled on these components at all but I’m in the process of researching them. I know it’s important to match the tone arm, and cart to it. What about the connects?

Someone has suggested a used JD9mk11, another suggested a used Ear834P.

Any suggestions?

Thank you for your input.

(I'm posting, therefore, this comment must be about the Herron Audio phono stages.) 

I personally own and have heard NOTHING better at any price than the Herron VTPH-2.  To my ears, it is not bettered by any phono stage, though I admit I have not heard the Allnic.  Nor have I heard the latest ARC reference phono stage.  Previous ARCs I've heard didn't beat the VTPH-2.

As a second choice, the Herron Audio VTPH-1.  They are available on the used market at a steal based on their performance. 

A call to Keith Herron might uncover a bargain.  He sometimes takes VTPH-1s in trade.  Getting a used VTPH-1 that has been refurbed and upgraded by Keith Herron is probably the best deal on the market today. 
I agree with adding an external phono stage to your set-up.  The HK is a good integrated.  However, with rare exception (like the Croft Phono Integrated) the phono stages in 2K integrated amps simply don't compare to a good external phono pre.  I love my Manley Chinook and can also recommend the Croft mentioned in a previous post and the Heed Quasar.  I've heard all three and they will all be a huge step up in sound.  I second the concerns about the Jolida - good sounding unit but way too much gain.  

Good luck, Scott
Much good but conflicting advise above, so I'm not going into a specific recommendation, but want to raise a couple of concerns that you want to address with whichever you choose.

- Low level phono signals are much more susceptible to environment noise from radio frequency interference(RFI), EMI, etc. If you live near radio or cell towers, etc. fighting noise is often a huge battle with phono playback. Solid state phono stages are generally much quieter than tube in such environments. Many tube-aholics have concluded that even with tube amps & preamps, the most practical solution is a solid state phono stage. Tube phono stages require the lowest noise tubes and often carefully matched pairs(i.e. often rare, expensive or both)

- Matching of each of these is important, so read up!:
a) tonearm compliance with cartridge
b) cartridge output with phono stage gain
c) cartridge impedance loading with phono stage options(or lack thereof) 

This stuff doesn't come easily without much study, so take your time or find someone you trust who can guide you through it. Most of all, trust your ears and try to listen to as much gear as you can if opportunity allows. If not, go slow, buy used so depreciation doesn't kill you, and then treat your purchases as long demoes. Cheers,
