Best Full-Function Preamplifier
VAC preamps have (optional) onboard phono stages that are fully "separates" quality, plus some. Only caveat is they use Lundahl SUT’s for MC gain, which is not my preference. So I patch in my own external SUT boxes and use VAC’s MM mode (all tube)... 
Let's Say A Guy Wanted To Chose Between A Koetsu Jade and
@rauliruegas Jade and Coralstone are both on the warm side here. I ended up preferring the more dynamic, detailed, "sparkly" Blue Lace. Onyx and RSP are in the middle. I like those too.  Yes, in fact, this year I have been exploring and enjoying ... 
ARC Ref 6 Tube Microphonics
This thread highlights the diversity of sensitivities we have to various noises and operational issues. Some manufacturers really need to add an alternate "high sensitivity speaker" reference rig to expose noise issues. Not ARC though - they’re do...

@lewm Yes - current, amperes! Silly me lol  
MM Phono Stages With Greater Than 40 dB of Gain?
@rauliruegas The Essential 3160 looks lovely! I’ll have to look more into it. I hate that most MM stages don’t offer loading options beyond 47Kohms. Opening this up to 100K, 500K, or 1MEG would afford SO much flexibility.

@no_regrets You’re welcome! I think about this stuff way too much lol. One correction: when I was saying "ohms to output" ratio I really meant the reverse "output to ohms". For an "ideal" transducer (and SUT match) you want as much output voltag...

@no_regrets The ruby plate is non-magnetic so it requires more coil windings / turns to effect the same output voltage. With the iron cross armature, the iron core basically makes coils more efficient at generating AC signal. So for example, let... 
ARC Ref 6 Tube Microphonics
The single ended connection between the Ref6 and H20 appear to be much more cooperative at 300 ohms / 50k ohms.  Wow, that's a world of difference. I believe Ref 6's circuitry is optimized to normally be best from XLR outputs (whether using SE ... 
ARC Ref 6 Tube Microphonics
Interesting, I am using the Ref 6 connected to a Hegel H20 and then to a pair of Harbeth 40.3XD. I believe the H20 has higher than average gain at 32dB. Also the output/input impedance matching of the Ref 6 and H20 appear to be just barely OK wit... 
ARC Ref 6 Tube Microphonics
I have owned a Audio Research Ref 5SE for many years, auditioned a Ref 6, and currently own a REF6SE for several years. Dead silent. Call Audio Research. I am sure they will guide you. Probably a repair. I would strongly argue against this acti... 
ARC Ref 6 Tube Microphonics
That "chime" (ting-pshhhhh) is extremely typical of 6H30, and is quite distinct to that tube type. If it makes you feel better, other brands of 6H30 preamps have the exact same deal - any type of click relay inside such a unit will set it off. The... 
MM Phono Stages With Greater Than 40 dB of Gain?
Folks are now recommending general-purpose MM/MC phono stages. OP’s specific cartridge is NOT a normal MC. It’s a 0.05mV mega-ultra-extreme LOW output and needs something more specific. He already has a matching 50x SUT (35dB gain), which ideally ...

@normb omg, the Glider SL is so damn good for the money, isn’t it? Makes you wonder how you get all that for under $1K. And yes, it absolutely clobbers the 2M Black. @wrm57 the Ebony TR is such an interesting model, and I’m sorry I never tried i... 
Hissing at idle through one amp but not another
System gain structure. This happens when you have high gain preamp, high gain amp, and sensitive speakers in various combinations (usually 2 or 3). The signal-to-noise ratio of the preamp really matters here. Tube preamps and tube amps tend to hav... 
Looking for a Warmer Sounding Phono Cartridge
I’m surprised the Shelter 901 Mk III didn’t do what you want. Though I haven’t heard the 901 yet it looks like a Harmony motor in an aluminum body, and that same motor in the Accord (titanium shell) is truly wonderful IMO, and not too far off from...
