The Carver Amp Challenge and the 21st Century and it's Failure
-70 dB puts it in the range of distortion. Agreed. Although in terms of voltage -70 db is only around 0.03%, which may or may not be audible depending in part on the particular distortion components it comprises....have you ever seen a transfer f... 
The Carver Amp Challenge and the 21st Century and it's Failure
Ralph ( @atmasphere ), I believe Erik is correct on this, in the first part of his post just above (but see below re the second part of his post). Note the description of the null test I provided in an earlier post (dated 3-3-2019): The null test,... 
Pop Sound in my speakers when driven loud from studio recorded CD sources.
Glad that the problem is finally solved.It seems that what I had said in a post which I subsequently deleted (because it seemed inconsistent with the sensitivity of the problem to the setting of the volume control), but which I quoted in a subsequ... 
RCA switch / 2 in 1 out or 4 in, 1 out.
Buy a pair of Y cables. If as it appears you mean connecting the outputs of both players to the receiver's tape2 inputs via a y-cable on each channel I would strongly recommend against that, since doing so would short the outputs of the two pla... 
RCA switch / 2 in 1 out or 4 in, 1 out.
I doubt that anyone here has performed a direct comparison between the two kinds of alternatives you cited, and even if someone has the results could very well be different in their system compared to yours. And from a technical standpoint I don’t... 
How to add depth for classical music
Good suggestions by Ralph ( @atmasphere ). Also, some years back Chesky remastered a few of the recordings originally engineered by Kenneth Wilkinson and issued them on CD, with spectacular results. I don’t know if they are available on any of the... 
Your favorite excellent quality/sounding LPs
I have found the following labels to have provided excellent sounding classical recordings on LP with a high degree of consistency, although unfortunately a number of them no longer exist or no longer produce LPs.Accent Astrée AudiofonCheskyDorian...

@mrdecibel Good question, MrD. Over the years it has become clear to me that sensitivity ratings provided by speaker manufacturers are very often and perhaps usually overstated by a few db. In some cases I suspect that the manufacturers are basing... 
Is there an ideal (ish) cartridge output?
Another aspect that also got me thinking about this, is when you crank the volume on an input of a cd player or DAC when nothing is playing you get silence, but when you do that with a phono stage you will quickly get noise when past a certain t... 
Looking for phono preamp suggestions
@three_easy_payments Re the Luxman EQ-500, I note that depending on the selection between the two LOMC gain modes it provides it presents the cartridge with a load impedance of either 40 ohms or 2.5 ohms. While the OP’s 0.3 mv cartridge has a reco... 
Educate me about gain and amp/preamp matching
The overall gain of the amp/preamp combination does in fact correspond to the sum of the gains of the two components (if the gains are expressed in db; if the gains are expressed as a ratio of voltage out vs. voltage in then the two numbers would ... 
Educate me about gain and amp/preamp matching
+1 Cleeds.Also, keep in mind that the difference between 30 watts and 50 watts is only about 2 db, in terms of voltage, power, and (everything else being equal) in terms of the resulting SPL.Differences in preamp gain will just affect the settings...

@speedbump6I’m guessing that it’s not increasing power like an amp does with wattage, but in some way increases the level of the signal going to the amp in a different way. Yes, that’s correct. It simply multiplies voltage, but does not multiply ...

@listener99 Yes, the website doesn’t make clear if the 98 db/2.83 volt/1 meter figure applies to the 4 ohm version or the 8 ohm version or both. But since Eric "suggests 4 Ohm for optimum performance," and the majority of Tekton purchases seem to ...

@listening99 Note that the sensitivity spec of the Moab is based on an input of 2.83 volts, not 1 watt. (These days an input of 2.83 volts is the most common basis upon which speaker sensitivities are specified). If it were an 8 ohm speaker the SP...
