How much gain is needed in a Phono Preamp for a 0.2 to 0.3mv low output moving coil?

I have been out of audio for 25 years and am now getting back into getting a system. I have looked at Manley Chinook, Ear 834p, and Audio research 5, 6, 7 Phono preamps, after reading thru many or post on Audiogon. All have about 57db gain to 60 bd gain. I have been looking at getting either a Dynavector 10x5, Benz micro Silver, Ortofon Quintet Black, or a used Benz Ruby Z (if I can find the money). Is 57db enough gain for the cartridges. I would also welcome feedback on the Phono Preamp. I am leaning toward the ARC PH7 or Manley. Either would be around the same price. I would prefer to stay with tubes. The turntable is a VPI Prime. Any help or opinion would be greatly appreciated.

I have the Chinook and upgraded the tubes to Phillips NOS. Just bought my second Soundsmith Cart -  the original Zephyr is on my VPI Scout 1.1 now (Zephyr is made for unipivot arm) and it sounds great. Have Primaluna pre and Dialogue Premium power amp, Martin Logan ESLs. Got the Zephyr MIMC Star MC at .4 output but have not mounted it yet. Hope it all works out. Not sure what output the PL pre and power amp provide. I did notice a little more gain when I replaced the Chinook stock Electro Harmonix tubes. I may be asking you some questions sbank. Juke4u let us know what you end up doing! Great thread.

I use a Dynavector XX2 MKII (.28 mv) with the ARC PH-7 (57.5 dB). My line pre is the ARC REF 3 (11.6 dB balanced) and the amp is an Ayre V5xe (26 dB). Noise and gain are not an issue. When the volume control gets past 50 (out of 104) my Vandersteen 3A Sigs (87dB) are at party. Normal levels for me are 25 -45. Even though the DV works well, no complaints, I can’t help but wonder if could work better with more gain. I would recommend carts from .4 to .6 mv. There are outstanding carts in that range.

I bid on a Pass XP 15 but did not bid high enough. Is anyone familiar with the Pass Xono?  How would you compare the Xono to the EAR 864P? I have read what I could find. Can the output on the ear be adjusted or is it set?

Juke,

probably least expensive way to find out what correct loading and gainwill mean to you is to buy or borrow an ifi 2 Phono stage. Plenty of load settings and 72db gain not to mention sound that will embarrass many Phono pres in the sub $3k. Don't buy or borrow the original ifi which won't get you the gain you need. In fact, buy one on amoney back deal from Music Direct. I don't think you will send it back. Yes, there is a meaningful interplay between load and gain.

I run my benz ebony lp-s on the graham phantom II and TW acustic raven 1 into the steelhead's mm input, 60db gain setting, joule la 300, music reference rm 10, quintessence stealth, and it provides plenty of gain.  Sounds good too!
