| Help connecting headphone amp to Levinson 38S I took a look at the manual for the model 38 preamp (not for the 38S, which I couldn’t find; the manual for the 38 is available at hifiengine.com if one is registered there).I realize that you said the manual was of no help, but assuming the manua... | |
| Would switching amps make a big difference? At 30 watts of output, the amp will put out that same 30 watts into any freq for an even tonal balance. @viber6No, that isn't correct, assuming the amp acts as a voltage source (as almost all solid state amps do, and as some tube amps do to a r... | |
| 4 ohm (or 6) Bookshelf speakers. Pass Labs 30.8 Or at least I am not doubling my volume like I thought I would be. A generally recognized rule of thumb guideline is that achieving a subjective perception of "twice as loud" requires either a 10 db increase in speaker sensitivity or a 10 db in... | |
| 4 ohm (or 6) Bookshelf speakers. Pass Labs 30.8 First, regarding...... is a speaker with sensitivity of 100 at 8 ohms as loud per watt as a speaker of sensitivity 85 at 4 ohms?If the specs are accurate (and speaker sensitivity and efficiency specs are often optimistic by a few db), and if the s... | |
| Would switching amps make a big difference? @cdc2 Excellent suggestion by Ralph (Atmasphere). In the absence of a Zero autoformer, though, I would just say that the amplifier output impedance should be a good deal lower than the numbers I cited for the Prologue Seven, which btw correspond t... | |
| Would switching amps make a big difference? Like a number of other PrimaLuna amps your Prologue Sevens have a particularly high output impedance. Stereophile measured 2.6 ohms for the 2 ohm tap, 4.5 ohms for the 4 ohm tap, and 8.5 ohms for the 8 ohm tap. The impedance of your speakers, whic... | |
| What do you consider "loud" for your system? I agree with everything in Mlsstl’s post just above, except that I would add an important clarification to the following statement:I can tell you that that 90+ dB dynamic range on a CD is largely unused. It’s important to distinguish between the ... | |
| Ceramic insulator cone under phono stage shocker! FWIW, under my phono stage (a Herron VTPH-2) I use and have been pleased with an Adona Multi-Element Platform, with attached cones that point downward. I installed it at the same time as the phono stage, though, so I can't comment on how much of ... | |
| Cassette Decks in 2019 Smkerry, thanks for your response.I should add to my previous comments about the Tascam 202MkVII that they pertain to playing pre-recorded tapes, which is what the OP has said he is interested in. I have not done any recording with this deck.Rega... | |
| Cassette Decks in 2019 Smkerry, can you describe your experience with the specific Tascam model that has been discussed (the 202MkVII), upon which your comments are based? For example, have you listened to it in your own system with tapes you are familiar with?Regards... | |
| Cassette Decks in 2019 ... why would one even consider cassette media would be worth listening too. Mark, to add to Uberwaltz’ comments I would feel safe in saying that if, as I did, during the 1970s and 1980s you had purchased a considerable number of cassettes that w... | |
| Cassette Decks in 2019 Late last year I purchased the Tascam deck you linked to, for $500 at B&H Photo Video. I commented about it as follows on 11-18-2018 in this thread: Given the mention of cassette decks in many of the responses, I’d thought I’d mention a curren... | |
| Can someone figure out the gain of this amp? Yes, that’s correct.I see that the BHK Signature preamp has a specified "sensitivity" of 1.3 volts, and a specified "output level" of 4.0 volts. Presumably that means that an input of 1.3 volts would result in an output of 4 volts, if the volume c... | |
| Can someone figure out the gain of this amp? Check out page 26 of the manual. You’ll see the following stated there: Voltage Gain:High Level to Output 1: 44dB High Level to Output 2: 15dB Phono to Output 1: 84dB Phono to Output 2: 55dB (Output 1 is the speaker output; output 2 is apparently... | |
| Ceramic insulator cone under phono stage shocker! I suspect it's more than coincidental that the PH-10 is solid state while the Chinook uses tubes. Probably having the cones in the new orientation lessens vibrations that previously were affecting some or all of the tubes.It might be a good ide... |
