| Has anyone upgraded their preamp with V-caps? Sherod, IMO if you are going thru the trouble and expense of replacing the coupling caps, do yourself a favor and put the good stuff in. Its not that much more! | |
| amplifier DB meters Hi Bob, VU meters usually have averaged response and don't show the peaks. LED-style units exist that do show the peaks; having watched a lot of these it appears that your typical peak is 3-6 db above the reading on an averaging meter, IMMV (defin... | |
| Can't find old thread on Balanced XLR phono cords Hi Groovey, seems to me there were several recently, focused more on balanced phono sections and the like.We've used this setup since 1989 and before us no-one was doing it.Any cable manufacturer can make a cable for you. If you have a five-pin pl... | |
| Efficient Dynamic Speaker with low-end punch? Classic Audio Reproductions can suit the bill with either the T-3 or T-1. Both are about 96-97 db with real bandwidth to 20Hz. Also a very revealing speaker and an easy setup in most rooms- I have mine about 6" from the rear wall. Easily driven by... | |
| Has anyone upgraded their preamp with V-caps? Sherod, the output of the MP-1 is direct-coupled; the pair of 0.1uf caps (the unit is also differential) are between the voltage amplifier and the vacuum-tube output buffer. | |
| Has anyone upgraded their preamp with V-caps? Just a note to those thinking of making the change (which we think is very worthwhile)Its a good idea not to change the value. Increasing the value to get more bass may cause the low frequency cutoff to go too low- lower than the power supply low ... | |
| Tube handling/designations Heat is the enemy of tubes- they ought to be kept clean of dust and fingerprints for the longest life. 6DJ8s and 6922s are capable of running a fair amount of current and so can get quite hot. | |
| amplifier DB meters We set the meters on our amps for full power full scale and 1 watt full scale. However they are calibrated for an 8 ohm non-inductive load. Any variance in the load will throw the reading off, sometimes quite a bit. They are handy for relative pow... | |
| Musicality vs Transparency & Detail The way you get 'detail retrieval' is to not create distortion. Distortion obscures detail. The way you keep it musical is by not adding subtle distortions that are sensed by the human ear as loudness cues (odd harmonics). Feedback as a source of ... | |
| Will an RCM make the Rice Krispies go away? FWIW I've found that phono preamps with feedback, particularly transistor units, will often enhance ticks and pops. When I started listening to zero feedback (passive EQ) preamps, I found that my LPs were a lot quieter than I had thought they were. | |
| Trying to match impedance It looks to me as if the Threshold was built to meet the balanced line standard, which is low impedance. The input impedance is set low to reduce ringing in line matching transformers that drive the input.There are not that many preamps that can d... | |
| Turntable Pre-Echo Sound....? I agree with UC -mostly- on this one, although working with mastering LPs, I find that pre-echo is actually a tape phenomena rather than LP. It indicates that the tape was stored before the LP was mastered- not a good idea as the energy of the tap... | |
| Zero feedback and class A,which is better? T_bone, you got it exactly right. Most SS amps make constant voltage with respect to load; on ESLs that is not the right response.With respect to the ZERO/OTL thing, we made a device similar to the ZERO about 10-15 years ago. It got to be a bit of... | |
| amps for Merlin VSM-MXE {quote]Can they be switched to 230v?[/quote] --Yes, they can. | |
| Zero feedback and class A,which is better? 'Lurk' is hardly the term!For a speaker like this, a zero-feedback amplifier will need a little help. Fortunately there are two things going for you- the first is that the speaker is an ESL and the second is that there is a way to deal with the im... |
