| Which SUT? .... for .3mv/10 ohms MC cartridge into 3mv MM input sensitivity impedance is what effects the soundtoo low = dull. too high = too bright As a general rule of thumb that is often true in the case of low output moving coil cartridges. But the effect is also dependent on the phono stage, and for that matter on t... | |
| Which SUT? .... for .3mv/10 ohms MC cartridge into 3mv MM input sensitivity As far as I can recall my Lionel transformer didn’t hum :-)Also, while I’m not certain I believe that in at least most of the models made in the 1950s or thereabouts those "transformers" were actually autoformers. Meaning that they just had one wi... | |
| can i mate my receiver mac 1700 as a pre amp to my mc 275 amp? It appears that the 1700 does not provide output jacks for its preamp section. Therefore I believe the only way you can use it as a preamp would be to connect a speaker-level to line-level converter between the 1700's speaker outputs and the 275'... | |
| Which SUT? .... for .3mv/10 ohms MC cartridge into 3mv MM input sensitivity Again, keep in mind that the higher the boost provided by a SUT the lower the number of ohms that will load the cartridge.I don't know of any SUTs which provide a bypass function, although perhaps there are some.Regards,-- Al | |
| Rel T7i matching up with Monoblocks The issue is not so much that the amps are monoblocks, but rather that they have balanced outputs. Therefore their negative as well as positive output terminals have full amplitude signals on them, and as noted on the rear panel of the amps their ... | |
| Who Here is Vertical Bi-Amping? Oldhvymec: When you can match a 200 watt amp for the bass, and a 50 watt (of higher quality) for the mids and highs. A point to keep in mind when horizontally biamping using two amps having much different maximum power capabilities, without using... | |
| Which SUT? .... for .3mv/10 ohms MC cartridge into 3mv MM input sensitivity That’s hard to say, Elliott (see the last paragraph on the first page of the writeup I linked to), but I wouldn’t suggest going much higher than 20x, if at all. For example, if you went to 30x (which is about 29.5 db, just 3.5 db more than 20x) yo... | |
| Which SUT? .... for .3mv/10 ohms MC cartridge into 3mv MM input sensitivity Q1) No, 3 mv is the input voltage for the phono inputs which will result in the main output of the preamp providing its rated output (3 volts, assuming that spec is the same for the MX110Z as for the MX110), when the volume control is at max.3 vol... | |
| Amps XLR vs RCA input impedance difference. Balanced input impedances are usually (although not always) defined based on the sum of the impedances of the two signal "legs," while of course unbalanced inputs have only one signal leg (per channel). In many and probably most power amp designs ... | |
| Why do most phono preamps lack XLR input even thought cartridges are naturally balanced? Thanks for the mention, Kijanki. To add further technical elaboration to this erudite discussion of esoteric matters, IMO the main reason "most phono preamps lack XLR input even though cartridges are naturally balanced" (quoting from the subject l... | |
| What do you sit on? I listen from Wassily Chairs. In addition to being a beautiful and classic design (see this Wikipedia writeup), their relatively low seating position results in my ears being at an optimal height for my particular speakers (Daedalus Ulysses), an... | |
| Bryston 9B SST2----Stupid Question The RCA output connector on the preamp for the left channel would be connected to the RCA input of the amp channel that is connected to the left speaker. The RCA output connector on the preamp for the right channel would be connected to the RCA in... | |
| Bryston 9B SST2----Stupid Question You would have to use two of the five amplifier channels, one for the right speaker and one for the left. The two speaker-level output terminals on each channel are + and - for a single speaker, rather than left & right.Regards,-- Al | |
| Classe Phono Stage An internal circuit board providing phono capability was optional with the CP-45. Without that board the phono/aux input functions as a line-level input, similarly to the other inputs. Since you have a streamer/DAC plugged into the phono/aux inp... | |
| Too good a post to waste Thanks, Grant ( @tvad ). You are correct on all counts. And yes, I am delinquent in updating my system description thread. There have also been a few relatively minor changes in the past year or so (mainly due to problems which have arisen wi... |
