| First impression: Herron VTPH-2A phono preamp For normal listening levels in your setup where is your vc positioned on your active pre and do you know it’s gain? Does it have a log pot? And what is the gain of your amp and efficiency of your speakers? Hi George,My speakers are Daedalus Ulysse... | |
| First impression: Herron VTPH-2A phono preamp He’s given you massive 64db or 69db of gain, use it, some poor saps only get 35db of gain with their phono stages and they have to listen to the preamps output gain stage’s noise. Hi George,I’m not sure you’re realizing that the 64 or 69 db of gai... | |
| First impression: Herron VTPH-2A phono preamp As for the 2.5v output figure into 20kohm at 0.03% distortion this is far less than what a cartridge has as a distortion, they are closer to 1% so to me that doesn’t mean much. Hi George,To be sure it’s clear, the point I was making had absolutely... | |
| First impression: Herron VTPH-2A phono preamp Wow! So bass rolloff would not be an issue that would result from driving low impedances such as 10K, with Keith’s design. But I would still take to heart his comments recommending against anything less than 20K. And his suggestions that for other... | |
| First impression: Herron VTPH-2A phono preamp Hi George,No, I don't know what the value of the coupling cap is, as I've never had occasion to open my unit. One reason being that I've never felt tempted to do any tube-rolling with it, and in the process perhaps messing up the voicing Keith ha... | |
| First impression: Herron VTPH-2A phono preamp Professorsvsu, congratulations and continue to enjoy! I know you will, being one of several other members here using the VTPH2 or 2A/ART-9 combo.Regarding passive preamps, the Herron phono stage is not suitable for driving a low impedance passive ... | |
| Help me pick a phono, pre and cart Sounds good! The version he recommended, which provides the lower of the two gain alternatives that are offered, is by far the version that is purchased most often. It should be suitable for all but the lowest output cartridges, certainly for th... | |
| Bryston preamps The very low input impedance of the 14B3 (7.5K unbalanced, 5K balanced) makes it unsuitable for use with the majority of tube preamps, as well as with passive preamps such as the Lightspeed. A tube preamp that comes to mind that would have no pr... | |
| Help me pick a phono, pre and cart @jetson The most significant adverse consequence of running the Herron or the ARC phono stages that were mentioned into your Ayre amp is, IMO, likely to be weakness in the deep bass region. That is because the output impedance of those phono stage... | |
| Help me pick a phono, pre and cart From the specs provided at arcdb.ws for both the PH-6 and the PH-8:Output impedance: 200 ohms Unbalanced. Recommended load 50K-100K ohms and 100pF. (10K ohms minimum and 2000pF maximum.) From the manual for the Herron VTPH-2A:We recommend ... | |
| Help me pick a phono, pre and cart I'd be careful about impedance compatibility between the phono stage that you choose and your Ayre integrated amp. The Ax-7e's input impedance of 20K unbalanced and 40K (20K per phase) balanced is too low to be optimal with either the Herron or A... | |
| Primaluna separates or Integrated? @ezstreams,Thank you for the nice words :-)I have no way of knowing if a similar problem would arise if a different PrimaLuna model than the OP was using in the thread I linked to were to be used with your Tritons. But it wouldn't surprise me if... | |
| Only One XLR (Balanced) Input - Cable w/ Two Sets of Output? XLR y-cables are readily available, but they absolutely should not be used for what you are proposing. They are used to route an XLR output to the XLR inputs of two components. Using them to connect two outputs to one input would amount to connect... | |
| Tekton Double Impacts Detroit is known for chili dogs🙂 Coney Island style! As someone who grew up in Coney Island I’d expect that to be quite a treat! Although my own preference in those days was for unadorned Nathan’s Famous hot dogs, at the original Nathan's restaura... | |
