| Seeking more 3d imaging, deeper/wider soundstage Realremo, now that you have sorted out that phase was a problem, it is worth it to play with the speaker placement again to get better results. If you were doing that with one speaker out of phase, the speakers will not be placed correctly. Have f... | |
| Phono/Preamp Discussion: The Missing Link OK- here is why not an SUT and basic phono section.In a word: transparency.We have auditioned every SUT we could get our hands on and they all have a signature. We also identified several other problems.One of them was the use of feedback to equal... | |
| Help on tube question The 6550 and KT-88 are nearly the same tube. They have similar bias points and the like, the big difference being that KT-88s are supposed to be more linear ('KT' refers to 'kinkless tetrode' IOW there is no kink in the linearity curve like a 6550... | |
| Preamp for Aesthetix / Atma-sphere Yes (we can also use them in our preamps). One of the driver tubes has a little more voltage on it, in your case the one that is at the edge of the chassis facing the power tubes. That one has to have either a -GTA or -GTB suffix if you use NOS; y... | |
| Unbalanced to balanced VPI junction box change? ^^ That is a good question! It has to do with how the source (phono cartridge) is driving the load, which is to say that the source impedance should be lower than the load by about 10:1.In the case of LOMC there does not seem to be a downside. LOM... | |
| Seeking more 3d imaging, deeper/wider soundstage Having one speaker out of phase with the other will result in loss of soundstage, poor center fill, reduced bass and overall lack of dynamic punch as the speakers are literally fighting each other.If you hook one speaker up out of phase, the more ... | |
| Why not magnetic tapes in stead of vinyl records? Kijanki, If your basement is controlled humidity then I would agree with you. Most basements though have much greater humidity (at least in this part of the world they do...) than the attic. So what we are disagreeing about is whether the basement... | |
| Unbalanced to balanced VPI junction box change? That's good! Here is something to consider- if you can hear the effects of cables in your system, I would guess that you installed the cables that sounded better. Now if you have been at this a while, you probably have replaced cables before, thro... | |
| Unbalanced to balanced VPI junction box change? I have a totally balanced system (all Ayre components) and can readily hear the difference in cables....I have a lot of respect for Ayre, but regardless if you can hear differences between the cable, some aspect of the balanced line system is not ... | |
| Preamp for Aesthetix / Atma-sphere ^^ Some of the new 6SN7s go for $200-$300/pair or more, while the garden variety of newly manufactured tubes are $35 apiece or less.Some examples are Sophia, Psvane and TJ Music. All have some form of a 6SN7 or VT-231 available and all have gotten... | |
| Seeking more 3d imaging, deeper/wider soundstage Realremo, to check to see if your speakers are in phase, you simply reverse the connections on the back of **one speaker only** - not both.If this works, you will immediately notice greater center fill and sharp images between the speakers. If it ... | |
| Why not magnetic tapes in stead of vinyl records? Kijanki, my recommendation is to work with tape for a while and then you will see that not only are my observations correct but also those of the NTA. (My statement was that tapes store in an attic much better than a basement, which is different f... | |
| Unbalanced to balanced VPI junction box change? Al has got that right. In addition Jonathan Carr's input mirrors my own experience in the design of phono preamps. **As a general rule of thumb** if you can hear differences between balanced cables it means that some aspect of the balanced standar... | |
| Preamp for Aesthetix / Atma-sphere Yes, but sadly I can't use this any where in my system. 8-(Yes, you would have to use a preamp that uses 6SN7s... FWIW the new boutique 6SN7s that have been showing up have been getting rave reviews by our customers. | |
| Seeking more 3d imaging, deeper/wider soundstage One thing that has been bugging me about this thread seems worth pursuing. Realremo- have you tried revearsing the phase on one of your speakers?If you have the speakers out of phase (which can happen for a variety of reasons) the imaging informat... |
