| Voltage mode vs current mode phono stages Not too sure how LOMI cartridges would work into a current driven phono, because of their high-ish inductance. Have you tried it? Or has anyone? | |
| Phono Stage upgrade to complement Dohmann Helix One Mk 2 Since you are the sole repository of "common sense", in your opinion, and since your opinions are all over this thread, why would you say there is no common sense here? I shouldn't bother to respond, but I cannot resist pointing out that I said n... | |
| Phono Stage upgrade to complement Dohmann Helix One Mk 2 Fremer is listening without measuring. Atkinson is measuring without critical listening. Thus they offer two entirely different perspectives. The reader needs to make up his own mind based on the total information. This sidebar has nothing to do ... | |
| Phono Stage upgrade to complement Dohmann Helix One Mk 2 Specifically, I have found that I favor OTL tube amplifiers to drive full-range ESL speakers. This category does not include conventional transformer coupled tube amplifiers. Why add another coupling transformer where it is not needed? A further... | |
| Phono Stage upgrade to complement Dohmann Helix One Mk 2 I, for one, would welcome the opportunity to audition a top quality phono stage that does RIAA in the digital domain. There's nothing inviolate about the precision capacitors, resistors, and/or inductors that are necessary for accurate RIAA in th... | |
| Phono Stage upgrade to complement Dohmann Helix One Mk 2 You have heard the JC1 and the Hyperion driving the same pair of Sound Lab speakers in the same room with the same upstream gear? | |
| Voltage mode vs current mode phono stages See above. For current drive the phono stage input impedance needs to be as near zero as possible so as to “see” the cartridge as a current source. It also has be amplified by current and to put out amplified voltage in response to current. That’s... | |
| Voltage mode vs current mode phono stages Just to embellish what Dover wrote, the upshot of his analysis is that for LOMC cartridges with very low internal resistance (10 ohms or less?), all other things being equal, a current drive phono stage makes a lot of sense (because the capacity t... | |
| Phono Stage upgrade to complement Dohmann Helix One Mk 2 What strikes me about "Channel D" and their many products is that they need a PR guy. First, the name of the product line (Channel D) is non-descript if not misleading (because it makes one think of Class D amplifiers, which are not exactly a la ... | |
| How does the VPI Aries II stand up to current mid priced tables? I know you addressed the question to tablejockey, but the answer is emphatically "yes". Phoenix Engineering over VPI ADS. Tablej will likely agree. | |
| Phono Stage upgrade to complement Dohmann Helix One Mk 2 Pani, if you mate the FM122 with a linestage having 12-18db of gain, you’d be in a good place to drive most amplifiers with most LOMC cartridges. (At the far end of that range, you’re adding 18db of gain which would be very capable.) Or did you me... | |
| Inexpensive Good Vintage Turntables? Clearthinker, You wrote, "You must be a scientist as, like most of the others, you have not evaluated the causes of environmental damage correctly. By far the most costly elements of product production and use are the creation and disposal of the... | |
| The past meets the future Sliced bread has its place, if you're making sandwiches for a bunch of kids, but not if you want really good bread. | |
| Does Having the Turntable Grounded Through the Right RCA Effect Sound Quality? One difference from one installation to another is whether the audio ground is identical to chassis or AC ground. Some designers like to place a small value resistance between audio and chassis ground, for noise abatement. Some use an arrangemen... | |
| Phono Stage upgrade to complement Dohmann Helix One Mk 2 I am not quite sure why you are so provoked by some of my opinions, but this line of argument is too silly to continue. I’d be interested to see a list of tube phono stages that you currently would endorse as competitive with whatever are the best... |
