| The Arm/Cartridge Matching Myth Halcro, I think I see where you are having difficulty. The FR-66 is not a "very high-mass" tone arm- although its on the high side for sure, but not 'very' high. Additionally, its tracking weight method uses a spring, which can reduce the effectiv... | |
| atmasphere 6as7g output tubes. If you want nice 6SN7s, we have gotten really good feedback on the Psvanes, Sophias and TJ Music tubes. This applies to the amps and the preamps. | |
| The Arm/Cartridge Matching Myth ^^ the above seems to read as if there is confusion between the resonance of the arm tube with the mechanical resonance of the arm mass combined with the cartridge and its compliance. The two are different.The adage that rules are made to be broke... | |
| RMAF 2014 Observations We had 'Into the Labyrinth' in high definition on our server. I did not hear anyone playing Dead Can Dance other than myself in our room. | |
| How does a step up transormer affect sound- George's advice is really sound- if you exceed 50% of the rating of the stepup/isolation transformer, it will degrade the AC power by adding distortion to the AC line. | |
| atmasphere 6as7g output tubes. The American 6AS7Gs can have issues, although we have found that the 6AS7GAs are the ones that are most problematic.Here is what we know about the American tubes so far:1) you get best results if your amplifier is a Mk3 or later.2) If NOS, the tub... | |
| Pre + Amplifier Recommendation Schubert, you might check with the manufacturer to see if removing and installing tubes while the unit is on is a problem. With our preamps, as long as you take certain precautions, its easily done. But I can imagine not all preamps are like that.... | |
| The Arm/Cartridge Matching Myth Many arm manufacturers provide a dubious figure for their arm's Effective Mass whilst a large number provide no figures whatsoever....😷The cartridge manufacturers simply provide a 'design target' for their compliance figures which can vary signifi... | |
| Why blind listening tests are flawed A customer of ours has been using a microphone to measure the results in his system as a result of minor changes he has done. He's on to something- you can clearly see how distortion has changed due to his changes. http://www.audioasylum.com/forum... | |
| Pre + Amplifier Recommendation You can't measure hiss on a tube tester- the best way to test tubes for noise is to listen to them. Or get known quiet tubes from a source (the manufacturer of the unit?) to send you a set. eBay is a good source of tube testers. There are some mod... | |
| The Arm/Cartridge Matching Myth Henry, Its more than being about warped records, if you read inbetween the lines of Kirkus's post above- if the effective mass is incorrect, you can actually have the stylus jump out of the groove of a perfectly flat, concentric LP.An excellent ex... | |
| Distortion with ARC Ref 150 and Maggie 3.7 **Most of the time** you can expect an amplifier with a balanced input to work just fine with a single-ended source.However, balanced line and single-ended operation are not normally considered to be compatible (by the pro audio industry). As a re... | |
| why balanced power last before component? Actually, if a GFCI is installed, it does not need the ground circuit to operate correctly. So what is needed is exactly as the NEC requires: each outlet must be of the GFCI type.If the installation does not have GFCI outlets for every component u... | |
| Distortion with ARC Ref 150 and Maggie 3.7 Agreed! Our amps are also fully balanced and differential; we made sure that it was no worries or loss of performance to use them with a single-ended preamp or source. | |
| why balanced power last before component? ^^ thanks for that, I did not find that in my search. Someone asked about balanced power on the OTL Asylum over on audioasylum.com, to which I responded:One thing about balanced power- equipment is not designed for it. Here is an example:If you ar... |
