To Variac or not to Variac? Too late now that you've done it, your were lucky.Good idea to power up slowly (over a few hours) with a variac after long period of non use.But!! being a big tube amps or any tube amps for that mater, one should never power them up without a spea... | |
Anyone have/ordered the Job 225? Yes grannyring your output impedance of your pre at up to 1kohm, (which by the way is not far off a 10kohm passive for drivability) should be fine for any poweramp with say 33kohm or higher input impedance. But you probably have gain in it also, i... | |
Treating Floor in New Construction - Reducing Footfall and Vibration Stickman, re your floors, you have been very spoilt by having concrete floors in your current room.Any suspended floor you have now will need the speaker isolated (de-coupled) from it, not spiked or coupled in any way, otherwise the floor will bec... | |
Anyone have/ordered the Job 225? Lightspeed is around 10kohm Grannyring, it mimics similar parameters as a 10kohm logarithmic potentiometer. So sources feeding it should be less than <1kohm, as I believe in the >10-1 ratio rule.And as for a tube amp and the Job not liking e... | |
Anyone have/ordered the Job 225? I’m sure if you used two of my or any passive pre’s in series the sound would be crap as well without using the Rothwell’s. I'm sure the Rothwell will be fine on the input of a high input impedance (>47kohm?) poweramp, if the pre before it had ... | |
Anyone have/ordered the Job 225? It’s not that the Rothwell’s themselves can "change the sound in not such a great way" But what the Rothwell’s can do is change the perceived impedance as seen by the previous stage, as then not to have a good impedance match. This can mainly happ... | |
Anyone have/ordered the Job 225? 0.75V sensitivity for full output! With all this gain and 94dB speaker why use a active preamp with gain?? Most sources give out more than 2v these days, even phono stages, and the Job I believe is 100kohm input impedance, all this is a perfect ma... | |
Lightspeed Attenuator - Best Preamp Ever? I thank you also miller65 for your glowing response to your purchase of the Lightspeed Attenuator.As for your question: "I have however noticed recently the display is showing what I believe is referred to as ripple and varies from 9.20 to 9.23 of... | |
Lightspeed Attenuator - Best Preamp Ever? Hi hammering, you echo the responses of so many owners when you said. "It simplicity (and price) impressed me so I took a chance and bought one. It has turned out to be one of my better hi fi choices."This "kiss" is the way I like to keep it, to g... | |
Mid-priced solid state options You can read all about the SF3.0's in this PDF download in the Lab Test section.http://www.google.com.au/url?sa=t&rct=j&q=&esrc=s&source=web&cd=2&cad=rja&uact=8&ved=0ahUKEwiSw6vfo8TKAhVn5KYKHRQGDa0QFgghMAE&url=h... | |
Mid-priced solid state options I would go with the Parasound Halo A21. As it’s circuit is designed by John Curl up there with Nelson Pass god status. And will drive just about any speaker load.And these SF Venere 3.0’s while an excellent speaker, have a bit of a nasty load at t... | |
Lightspeed Attenuator - Best Preamp Ever? Hi, this is the one I sometimes use, it's encased in black plastic and is also 6800mAh's which should see around 3 weeks of Lightspeed listening before a recharge is needed, which only takes around an hour.http://www.ebay.com/itm/EU-DC-12V-6800mAh... | |
Parasound Halo JC-1 for Thiel CS 5i Yes I know, that was a tongue in cheek question mark, with eyebrows raised. Let’s just say I like Class D for >4ohm bass/sub duty)Cheers George | |
Parasound Halo JC-1 for Thiel CS 5i No I don’t, wish I could, in Australia they are over $18k. And to buy a s/h pair in the US is cheap enough, but shipping for me is a huge cost, and then I’d need to convert them to 240v, but this could be just a primary transformer tap change if l... | |
Parasound Halo JC-1 for Thiel CS 5i dsper Hi, Well, here is the latest on the great experiment with the Parasound A21.At 11 o’clock on the preamp while playing Fleetwood Mac "Rumors", the A21 one started to clip and went into protection mode. I routinely run the W4S ST1000 at 2 o’cl... |
