ChatGPT Willsenton R800i 805 vs Line Magnetic LM-805ia
I should think Skunkie would be upset to be accused of being male! Also, she has studied and modified the R8 extensively, but has declined to try the R800i as it is too heavy for her to move around.  
Considering a New Tube Pre-amp
I've spent two months now with the Wyetech Ruby STD, and I have no regrets. I can't speak to imaging and soundstage as I have only one functional ear, so I don't hear stereo, but in terms of sound quality it does all I was hoping for. It is much l... 
Tubes to replace stock in Quad II Forty's amps?
Waking up an ancient thread here! I've owned Quad II/Forty amps for nearly 18 years, and have experimented with various tubes. I haven't found a better rectifier than the Svetlana (St Petersberg) 5Ц3C black plate. I have been using Sophia Electric... 
Ortofon Cadenza Bronze, Blue, Black
@abucktwoeighty I've had a Kontrapunkt C (the father of the Bronze), a Cadenza Bronze, and also a BM Ruby 3 and LP-S. I like to listen to the Ortofons now and then, but could listen to the Benz cartridges all day. They are very different: after th... 
Last night the Music took over….
First full day of having my tube amps back in service. It's like sinking into a hot bath after a long day -  so nice! Playlist included: Fleetwood Mac - Chalk Farm Blues Vol.1 Doobie Brothers - Takin' it to the Streets The Who - Who's Next Dic... 
Will a record weight harm the motor in a direct drive turntable?
I just weighed the screw-on clamp from one of the SMEs, 355g (12.5oz). A tiny fraction of the weight of the platter (which I can't weigh: it swamps kitchen scales, bathroom scales are inaccurate and I no longer own a set of baby scales!)  
Impedance Loading for SS Hyperion
Six hours of driving tomorrow, but at the end of it I should have my right channel back. I've ended up preferring listening to one tube amp and one speaker rather than the old YBA-1ɑ. And no hum that I can hear!  
Impedance Loading for SS Hyperion
The manufacturer suggests 470 - 1000 ohms.  
Impedance Loading for SS Hyperion
Not sure, I haven't been able to find a circuit diagram. But I'm using the NuVista Vinyl now, which has solid state amps for MC use.  
Impedance Loading for SS Hyperion
Quad 24p, yes, fixed at 10Ω for MC. See here. As to why, you'd have to ask Tim deParavicini, who designed it, and that will prove difficult now.  
Impedance Loading for SS Hyperion
I checked this morning and all four cartridges are humming, the Hyperion least of all. But I've gone from 40W amps to an 85W amp. Turn the volume down on the pre-amp dummy! Problem solved.  
Impedance Loading for SS Hyperion
I used the Sussurro MkII ES with a VAS transformer (1:10) and enjoyed it greatly, and found no downside when I resurrected the NuVista Vinyl to using it with an input set to MC. So when I got the Hyperion I plugged it straight into the NuVista. P... 
How are you playing your precious MONO Vinyl?
@billstevenson If what Ortofon told you is true, then all of us who can hear a difference between a true mono cartridge and the mono button must be mistaken, which seems unlikely. I spent a long time examining the description they give of the Cad... 
Grade Master3 cartridge--Moving Iron Design
I thought I had heard the term 'variable reluctance' applied to them? Which looks to me as if it a variant on the MI principle—see bottom right of this diagram from Gramophone in 1966:  
Grade Master3 cartridge--Moving Iron Design
@bdp24 Glad to hear of the option for a line contact stylus with the Maroon. I lived happily with my Reference and Jubilee until I had to send my Reference back to John Wright for a rebuild. Learning that he was about to retire I started to explor...
