| First impression: Herron VTPH-2A phono preamp that the manual recommends 50K or more as being optimal Yes as I said before that could very well be because of the output cap size, as you know 400ohm is fine to drive a 10kohm load. 1:20 ratio is no problem even 1:10 alsoWe’ll find out that cap... | |
| Have Passive Preamps Finally Come of Age? Fortunately, the combination sounds damned good Later then you could if you want, try from the reports a very good external tube buffer that has a low 150ohm output impedance, that is the new iFi Micro iTube2 tube buffer. I look at at this and se... | |
| First impression: Herron VTPH-2A phono preamp almarg I can see where your coming from Al, the 400ohm is fine, as you say if the output coupling cap is too small there would be some rolling off the bass too early with a 10kohm passive. I just did some calculations and if that coupling cap i... | |
| First impression: Herron VTPH-2A phono preamp Yeah I saw that with the 4B cube it has two switchable gain settings. Here’s something you may like to know, "if" this gain changing is done where most are done, the same way I used to do my tube or solid state amps I built, via changing the nfb (... | |
| First impression: Herron VTPH-2A phono preamp Yes do try it, because with all that gain the Herron has, you may as well use it all and not have more noise from active pre’s that you’d have to turn right down to throw away the gain of the Herron. Do you know what the impedance of your Goldpoin... | |
| First impression: Herron VTPH-2A phono preamp professorsvsu First impression: Herron VTPH-2A phono preamp rob67 has one of these Herron’s phono stages, and because it has nice low 400ohm output impedance for a tube and high (69db) of gain, he probably doesn’t need any more gain from an acti... | |
| Have Passive Preamps Finally Come of Age? tweak1 OP well this could b a case of the specs don't tell the whole story, because it's probably the most authentic sound I've ever experienced in my home I believe you, as I said to you two posts back, " Tweak1 It may sound good". But you... | |
| Have Passive Preamps Finally Come of Age? George, your info would be spot on IF the AA did not have 2 gain options Yeah I saw the 2 x gain options specs, neither will give an input impedance to let your Hattor be good match with it, it just changes the gain.Cheers George | |
| How much do I need to spend to get a preamp that sounds better than no preamp? bache129 posts07-16-2018 6:51am@honashagen you ask question , the answer is very simple Absolutely no difference how much money you can spend , the pre amplifier -is device can change the sound in only one side- make sound worse. The ideal preamp... | |
| Have Passive Preamps Finally Come of Age? tweak1 OP Tweak1 It may sound good, but I don’t want to burst your bubble, you should have asked, if your still using your Hattor passive, you didn’t heed what I said about your EP 100.2 amp being only 19kohm input impedance, and not the best mat... | |
| Absolute top tier DAC for standard res Redbook CD SimAudio was still making high end CDPs that could cull every detail out of a paltry 16/44 CD. This was an extremely good sounding SimAudio cdp, that used R2R ladder dacs and had a separate power supply, hard to get anything today that can do Red... | |
| How much do I need to spend to get a preamp that sounds better than no preamp? I don’t understand why you keep posting that. Because it was the original balanced power supply direct coupled (matched) complimentry jfet buffer that Nelson designed for the Lightspeed.Afterwards it became (I believe the cruder) unbalanced supp... | |
| How much do I need to spend to get a preamp that sounds better than no preamp? Too bad your thing isn’t balanced. It really limits it’s usefulness with a Pass amp Not really as "my thing" as you so quaintly put it, is used with many Pass amps they have rca as well, and those that don’t my customers use these http://www.card... | |
| What is an acceptable level of transformer hum on a Krell S300i? What is an acceptable level of transformer hum on a Krell S300i? It could be that the bias is too high taxing the transformer more, so it will hum louder.From memory the 300i I had for repair ran just warm after an hour of being on with no musi... | |
| How much do I need to spend to get a preamp that sounds better than no preamp? Looks like someone didn't like what I posted and got it removed, it will come back once looked at by admin, with if any modifications done to it so it's not so insensitive to their feelings.Cheers George |
