| A New Ground -- Benefits of introducing the Synergistic Research Active Ground Block SE @whart If you have a DVM there is a simple measurement that will tell you if the amp/preamp/whatever is properly grounded.With the unit unplugged and out of the system, the DVM set to the Ohms scale:The center pin of the IEC connection (or ground ... | |
| New Technics SL 1200 GAE Hello Norb, the nice thing about the Technics is its reliable and is not likely to need any service likely for decades if its not abused.Its a bit of a statement that no turntable has been more speed stable than the SP10 MkIII in the succeeding d... | |
| RMS Power? @almarg Widespread usage of incorrect terminology doesn’t make it correct. Just as widespread misuse of the English language doesn’t make it correct. For example, many people would say that they could care less about this topic, even though tha... | |
| Bass in Phono Stages I avoid SUTs on account of they rob the phono of detail and often bass impact too. The Jensens are some of the best out there FWIW. | |
| RMS Power? The term refers to the fact that if you are to calculate the output power, then the AC voltage used in the calculation must be RMS volts.To do this, first find the peak to peak AC voltage that is the output of the amplifier into a known load such ... | |
| A New Ground -- Benefits of introducing the Synergistic Research Active Ground Block SE @folkfreak No. The ground of the arm is independent of the audio signal. In fact what is happening is that the tone arm is a balanced source which in most cases is being operated single-ended. That's why you wind up with that grounding wire which ... | |
| A New Ground -- Benefits of introducing the Synergistic Research Active Ground Block SE @folkfreak Sorry Ralph -- you're dodging my question. If I accept your argument then installing the grounding box fixes all of the issues that the designers of the original equipment caused by (as you hypothesize) grounding the chassis of some ... | |
| Could someone suggest a decent audiophile cartrige for a Technics dj TT? We use a Grado Gold on our older Technics SL1200 which we use in our mastering lab to listen to cuts we've made on the lathe. I've yet to see it mistrack. | |
| A New Ground -- Benefits of introducing the Synergistic Research Active Ground Block SE Hello Al,The resistor is there to prevent ground currents and often 10 ohms is enough to do the job, just as you see in the old Dynaco gear. I like a little more myself, and its not a bad idea to place some high current diodes in opposite directio... | |
| A New Ground -- Benefits of introducing the Synergistic Research Active Ground Block SE @folkfreak if that was the case then why would grounding the stands after everything else had already been grounded to the SR box make an improvement? And why would changing the cables used for the grounds make an improvement? I use equipment ... | |
| A New Ground -- Benefits of introducing the Synergistic Research Active Ground Block SE I did a survey of a number of grounding systems by interviewing the owners and having them do a few tests (as best as I can make out, these were similar to the SR, but none of them were SR units). What I found was that in audio systems where a gro... | |
| Class D is just Dandy! If this "effect" has been remedied, or if I was just imagining it all, maybe a summer amp?Design plays a huge role! Some amps are not very involving and some are.Some class D amps employ Delta-Sigma processing, some are simple Delta, some are sel... | |
| Class D is just Dandy! But any speaker manufacturer worth his salt will tell you that doubling up on low order high power filters at or around the same area has it own set of problems with ringing ect.While this is true, this does not translate to the filters used in ... | |
| Balanced But Not Fully Balanced There is no good way to know without really understanding circuitry when you see it, so usually the best means is to ask pointed questions of the manufacturer. Quite often though the fact that the circuit is 'fully balanced' will be a selling poin... | |
| Can This Amp Power A 50 Foot Speaker Cable Run? @mitch4t you can still run balanced lines if you want. For something like this I’ve run the preamp into a set of line transformers at the preamp end, run the balanced cables can converted back to single ended using line transformers at the other e... |
