| Phono stage gain setting to match preamp and power amp capabilities Hi Mark,First, kudos for stating your question so thoroughly and well.Clearly the hiss is being caused by something upstream (ahead of) the volume control mechanism in the preamp. Looking at the preamp schematic at arcdb.ws I see that the volume c... | |
| Thought on OTL tube amps Upon re-reading my previous post, to be more precise it occurs to me that I should re-word the second paragraph as follows:The point, though, is that you and Realdeal appear to be envisioning (incorrectly) that autoformers behave as if they are in... | |
| Thought on OTL tube amps Xonex77, as someone with multiple degrees in electrical engineering and multiple decades of experience designing and managing design of analog and digital circuits for advanced defense electronics, I can assure you that I am well aware that pla... | |
| Synergistic Red Fuse ... I’ve never used after-market audiophile fuses before; how do you know if they are made with the same tolerances as a stock or a Buss fuse for a given amp value?The major manufacturers of non-audiophile fuses, such as Littlefuse and Eaton/Cooper Bu... | |
| Phono Stage with Two Line-outs Great! Glad it worked out, and thanks for letting us know.Best regards,-- Al | |
| Would someone explain what "up sampling" means and how it can affect the sound? But what I am saying, and I'm sticking to it, at least for now, is that knowing about the mechanics of upsampling or what DAC chip is not going to matter one iota to whether you will like the player. I know some people believe that each DAC ch... | |
| Thought on OTL tube amps Realdeal, as I indicated in my response to the very similar comment that was made by Xonex77, that is simply not correct. A suitably designed autoformer can transform voltages and impedances no differently than a two-winding transformer can. Altho... | |
| Would someone explain what "up sampling" means and how it can affect the sound? I completely agree with Gdhal that all available information should be considered. For example, as Mapman alluded to and as I have stated in a number of past threads, specifications can often be particularly useful in **ruling out** components fro... | |
| Use 4 or 8 Ohm output tab for norminal 6 Ohm speaker? According to this review your speakers have a nominal impedance of 8 ohms, and a minimum impedance of 6 ohms. Also, the reviewer states that he found them to be easy to drive, and that they provided good results with an amplifier and a receiver t... | |
| Synergistic Red Fuse ... I’ve been thinking, my Hegel H30 uses a 15 amp slo-blo so theoretically if on a 15 amp outlet, the breaker will trip and don’t need a fuse ... just hard wired it. But since it’s on a 20 amp line, MAYBE not a good idea. I’m just speculating and not... | |
| Neutral electronics are a farce... I thought audio waves moved at the speed of sound, and light waves moved at the speed of light? This is the kind of crap I’m talking about. At most frequencies, audio waves that are in the form of electrical signals travelling through cables trave... | |
| Thought on OTL tube amps Ralph (Atmasphere), I think that when Xonex77 refers to "increasing the impedance of a speaker" in the second sentence of his latest post, he is referring to increasing the load impedance seen by the amplifier, for a given speaker. But more signi... | |
| Biwiring an Amp into a Single-wired Speaker? That amounts to putting the two pairs of conductors in the cable in parallel, which could very possibly be sonically beneficial. Although there is also at least a small chance that the results may not be subjectively preferable.Paralleling the two... | |
| One entry-level IC, one really good IC. I agree with the others that the only way to know with any certainty is to try it both ways, as many variables are involved. Including the technical characteristics of the particular components that are being connected, the particular cables, and... | |
| Most unusual/mesmerizing female voice. Back in 2010 I had cited several classical and opera performers in this thread. In the pop, folk, and jazz genres I’ll add the Australian singer Judith Durham, who was (and sporadically still is, ever since the group was formed in the 1960s) a mem... |
