| What does an impedance-matching issue "sound" like? @georgehifi George, I understand what you are saying about the speaker’s impedance being challenging for a tube amp in parts of the bass region. But note that the OP has indicated that the addition of the second amp, with the two channels in each ... | |
| What does an impedance-matching issue "sound" like? @georgehifi As I've indicated multiple times, the amp is not being bridged!Regards,-- Al | |
| What does an impedance-matching issue "sound" like? @jsqtI don’t envision any possibility of damage. But whenever the impedance of a speaker is significantly mismatched to the load impedance a tap is designed for there may be compromises to both maximum power capability and distortion performance.A... | |
| What does an impedance-matching issue "sound" like? More than likely the impedance of the speaker is too low for the amps in this configuration. That would probably be the case if the amp were in fact bridged, as was initially indicated, since as you probably realize bridging causes an amp to "see... | |
| What does an impedance-matching issue "sound" like? Erik, I've seen some cases in which paralleled operation of the two channels of a stereo tube amp has been recommended by the manufacturer. Examples include the McIntosh MC275 and the old Dynaco ST-70, despite the fact that like the OP's amp thos... | |
| Can I use a split? While the DAC has a tube-based output stage and therefore might have a relatively high output impedance and consequently drive capability that is somewhat limited, the 100K input impedances you mentioned for one of the integrated amps and one of t... | |
| What does an impedance-matching issue "sound" like? First, to be precise it sounds like what you are doing is paralleling the two channels of each amp, which is not the same as bridging. (Although the term "bridging" is sometimes misused to refer to "paralleling"). Bridging involves operating the t... | |
| Best Way for my TT to reach my Pre-Amp!? I wish I understood how that all worked. Impede sounds like it’s resisting something. So if the Marantz has low impedance then why would a tube amp have a hard time with it? So would I also want to make sure the operating ohms of a tube amp is on ... | |
| Can I use a split? There is no risk of damage. Whether or not sound quality is compromised depends on the output impedance of the DAC, the input impedances of the headphone amplifier and the power amplifier, and possibly also on the lengths and capacitances per uni... | |
| Best Way for my TT to reach my Pre-Amp!? I found a report that the cartridge capacitance for the MP-110 is either 100 or 300. As I said, "various anecdotal reports I found regarding what capacitance may be optimal for it are inconsistent and inconclusive." Those are very different numbe... | |
| Best Way for my TT to reach my Pre-Amp!? Can somebody teach me how the capacitance works for matching to my Nagaoka MP-110? Unfortunately it appears that the manufacturer does not provide a load capacitance recommendation. And various anecdotal reports I found regarding what capacitance... | |
| Best Way for my TT to reach my Pre-Amp!? How much of a problem the capacitance of an RCA extension would cause, if any, depends on the particular cartridge. Let us know what that is. Hopefully its manufacturer provides a recommended load capacitance range.Also, the input capacitance of t... | |
| Klipsch Headphone Pre-amp Hookup Generally speaking it is preferable to connect a headphone amp to the tape outputs of a preamp, to keep the signal path that is used for headphone listening as simple as possible, **IF** the preamp's tape outputs can provide adequate drive capab... | |
| Congratulations Atmasphere! @timlub Hi Tim,Thanks for the mention, but of course my knowledge of the design is limited to what is said in the patent. And the Abstract at the beginning, supplemented by the figures (especially the first three) seem to me to present a good c... | |
| Is the Preamp section of the DEQX as good as a separate one? FWIW I've been happy using a DEQX HDP-5 as my preamp. It replaced a Classe CP-60.I'm not sure how relevant that is to your question, though, as the PreMate is a somewhat older model than the HDP-5. (The PreMate Plus was introduced around the s... |
