| 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... | |
| Phono Stage upgrade to complement Dohmann Helix One Mk 2 Keep in mind that Raul has a fanatical hatred for any component that uses a vacuum tube. His judgement is not objective. In my opinion, your best course of action is to try to audition as many of these high end phonoline stages as you can, both tu... | |
| EAR 834P MM/MC options help Better in the out position with what cartridge? | |
| Dust cover up or down? That’s what she said. | |
| Turntable Identification This is a classic high end system for the late 50s or early 60s. Marantz 7C and 8B plus TD124. |
