| Tube PHONO preamp interference - RFI, EMI, bad grounding? @filipm Although I agree with most of what @theaudioamp has suggested, I'm yet to be convinced this is actually the fault of the phono section, even though the phono section is clearly able to amplify the noise. First off the 12AX7s have nothin... | |
| Added an SUT...not sure I understood this @woofhaven1992 Sounds to me as if the SUT is wired backwards. If it were me to verify this I would grab a few adapters and hook it up 'backwards' and see if the gain increases. If it does, I'd send the unit back for repair and if not in warranty... | |
| MoFi controversy In the other side those woofers goes down to 16hz and common sense ( not with technical foundation. ) tells me that it does not play way higher than its crossover design at 450 and as a fact still have a first order filter through the in series i... | |
| MoFi controversy @rauliruegas After what I posted here : do you still think that I must return the caps to the woofers crossover? As @theaudioamp pointed out, some music may sound alright but other music may not; its likely the speakers will be less neutral d... | |
| MoFi controversy Which kind of problems could be to appear in the woofer or amps @rauliruegas Many woofers break up at higher frequencies. The breakups are great in a blues guitar amps but they really aren’t good for hifi. Breakups are portions of the cone th... | |
| MoFi controversy My last move was to take out the caps in the speaker woofers crossover and left only the pure silver ribbon inductor and I will try to do the same with the speaker tweeter silk dome. At the end the best cap is no cap at all. @rauliruegas One im... | |
| Looking for a preamp with XLR connections While balanced and differential circuits are usually superior, it is not universally so. I’ve seen measurements of at least half a dozen products for which the single-ended connections resulted in the same or better performance than the balanced ... | |
| MoFi controversy After Ampex/Quantegy went out of business, I had questions whether I could tolerate the sound of new tape... some of it sounds worse than PCM recording - just my opinion. @moonwatcher Tape does not have much of a 'sound'. Tape technology does. ... | |
| Solid state or Tubes preamp phono stage. @bigmac1963 Here's something to try: Put both preamps side by side. Do not use any loading on the cartridge other than the stock 47KOhms. Use the same LP and listen to both. Does one of them seem to play more surface noise than the other or soun... | |
| Lowering Tube power amp output @tubelvr1 The more powerful you make a tube amp (unless its an OTL) the more limited its bandwidth becomes, due to the output transformer. What this means is that for the most part smaller tube amps sound better (except for OTLs where bigger ones... | |
| Looking for a preamp with XLR connections We've been doing balanced line preamps for home audio longer than anyone else. We did it because if you support the balanced line standard, you can get off of the interconnect cable game and not have to worry about their 'sound'. It didn't occur ... | |

| Class D amplifier with TPA 3250 board As long as you don't push them too hard, it can be a bit surprising how good many of these little amps can actually sound. Of course then you start to wonder how good it can get... In our own work on class D amps (we have a design entirely our own... | |
| MoFi controversy @blisshifi I'm sure they work fine! As with all things, so much in digital depends on execution. I would not expect any greater dynamic range if you are dealing with sources that use compression to begin with. But you might have greater resolution. | |
| MoFi controversy Anyway, it seems like one of their advantages is process, apart from custom made Tim de Paravicini analog paths (probably preamps, amps and modifications to the lathe?). They are able to cut an acetate, have it plated and pressed and listen to it... |
