| Phono Stage upgrade to complement Dohmann Helix One Mk 2 Hmmm. . .I’m back to the consideration stage: apparently, the most neutral approach to add a HPF in my current system is via a high-grade capacitor. However, these capacitors only give a 6 db / octave adjustment, which means starting at 80 Hz (so ... | |
| Phono Stage upgrade to complement Dohmann Helix One Mk 2 @holmz My pre-amplifier has two outputs: RCA and XLR, so I can run the RCA to the amplifier and the XLR to the subwoofer, or vice-versa, as the amplifier has both RCA and XLR inputs. I was leaning towards a lower crossover for the HPF, somthing ... | |
| isonic CS6.1-PRO ultrasonic record cleaner Not to dissuade anyone, but the where are the transducers, and how many are there? It looks like it’s only got 80 W power to a 48 kHz transducer(s). The cheap VEVOR has 3 x 40 kHz transducers at 180 W (3 x 60W) at the base. The Degritter has 2 x 1... | |
| Phono Stage upgrade to complement Dohmann Helix One Mk 2 @mijostyn Understanding that digital LPF is better for sub woofers, can a high grade analog capacitor (e.g. silver Duelund CAST) be used for the HPF to the ESL with good results? What’s the main disadvantage to using an analog HPF via an in lin... | |
| Phono Stage upgrade to complement Dohmann Helix One Mk 2 @lewm because of the quality components of the pre- and amp, I am leaning towards an capacitor HPF, as opposed to running it through the sub, which just has a standard 6db per octave HPF, which would just be a standard, probably low-grade capaci... | |
| Phono Stage upgrade to complement Dohmann Helix One Mk 2 Correction: I finally found a diagram of the back of the Velodyne subwoofers under quick start guide on their website. . But it’s a very poor diagram, and doesn’t explain anything about the HPF, LPF, etc. It looks like their target is the home the... | |
| Phono Stage upgrade to complement Dohmann Helix One Mk 2 @holmz I was just reading multiple reviews about various HPF and they all say that there is a noticeable affect on SQ. But I suppose it's worth a trial. The current problem is finding the best ones to initiate this trial with:. Vandersteen, Ma... | |
| Phono Stage upgrade to complement Dohmann Helix One Mk 2 @rauliruegas @lewm Which Velodyne subwoofers would you recommend for best match and highest quality? What about Martin Logan subwoofers, or other brands? (Velodyne has no photos of the back of their subwoofers and no diagram of connections on t... | |
| Phono Stage upgrade to complement Dohmann Helix One Mk 2 @rauliruegas Yes, you would be correct that I have no experience with subwoofers. Does the Velodyne insert into the system between the pre amplifier and amplifier, with both a LPF for it's own amplifier and an internal HPF that then is sent to ... | |
| Phono Stage upgrade to complement Dohmann Helix One Mk 2 @rsf507 Yes, to a casual observer, you may wonder why we are talking about subwoofers on a thread that started with phono stages. Well, the phono stage question was resolved rather quickly and emphatically in the first few pages of the thread, w... | |
| Phono Stage upgrade to complement Dohmann Helix One Mk 2 Unfortunately, the more I read about HPF, the less inclined I am to use them: everything that I’ve read so far indicates that their use does impact SQ. Additionally, here’s a paragraph about higher order HPF influencing signal moreso than lower o... | |
| Phono Stage upgrade to complement Dohmann Helix One Mk 2 @lewm Thanks for the clarification. My favorite pieces involve the cello or cello and piano. (Yes, Bach, but also Beethoven and Brahms.) Consequently, I was thinking that the crossover should be below the lowest cello note, which is 44 Hz, as... | |
| Phono Stage upgrade to complement Dohmann Helix One Mk 2 @lewm Is there such a thing as an active analog high pass filter, or are all analog high pass filters passive? Thanks. | |
| Phono Stage upgrade to complement Dohmann Helix One Mk 2 @lewm So, with the Velodyne Digital Drive subwoofer, the entire line goes through the subwoofer from the pre-amplifier? And the Velodyne has both a high pass and low pass filter, which the high pass filter line then goes to an output line into t... | |
| Phono Stage upgrade to complement Dohmann Helix One Mk 2 @rauliruegas By complicated, I was referring to the act of installing an in-line digital high pass filter after the pre-amplifier, which would require an ADC and then a DAC before the amplfiier. . . and not sure how it would then affect the SQ, ... |
