| Ocellia speakers and power If you want bass into the 20s or even the 30s, you will need a sub with either one. That 12" is nice, but even in a big cabinet it won't go all that low. It just goes lower that any full range 8" will do, but that means maybe 38-40Hz at best. | |
| difference between an active and a passive preamp? I can't envision a reason why the length of the cable between source and preamp would be any more critical than with an active preamp.With passive controls, the cable length is quite critical as is the construction of the cable. The interaction is... | |
| Setting tube bias I agree with Gmsasso- it *is* strange for all 4 tubes to be too 'hot' all at the same time. Really seems to point to the amp not having enough bias voltage in its bias supply. | |
| What the heck is bias anyway? Hey Stanwal, transistors have to be biased too... and for the same reasons. | |
| shield to pin one of xlr Glai, Usually you will want pin 1 tied to the tone arm ground. This would then also be the ground connection of the phono section. While there may be no difference in noise that you can hear, this will eliminate loud pops that can show up due to s... | |
| Ocellia speakers and power The 8" seems a bit faster, and the 12" has more bass. | |
| Setting tube bias I would get the KT-88s tested. If they are OK, its possible that the bias supply in the amplifier is having problems. | |
| Ocellia speakers and power 25 watts or so is all they are rated for if I recall right. The speaker likes a bit of power so I would put as much as you can on them. We used our S-30 on them to very good effect. Any smaller tube amp should do the job; a lot will depend on your... | |
| Interface: Cartridge-Preamp or Cart-Tonearm? Raul has good advice. If the cartridge does not work with the arm, you can pretty well forget about the preamp somehow fixing things! | |
| Amps for Sasha I see it more in the way that ,if a certain voltage level doesnt drop with a heavier load(lower speaker imp ) than it is automatically shown that that amp is capable of instant greater current delivery meaning better loudspeaker unit control (impo... | |
| Zu Soul Superfly Gopher, you and I are on the same page with the Sovtek 6SN7s. We've not used them in over 12 years. Are they what were in your S-30 when you had it?? | |
| Who is the KING of MONOS? Rockitman, there are more class A amps on the list than Pass Labs. Well, at least *one* more anyway. | |
| Amps for Sasha I would definetively take the stereophile measurements seriously ,i consider it a magazine with a more scientific aproachAndromedaaudio, take a look at this link:http://www.atma-sphere.com/papers/paradigm_paper2.htmlStereophile does not recognize ... | |
| What does one purchase after owning horns? Weseixas, I think T-Bone has a good point- where is the science that says that horns are 'discombobulated'? Do you have a link that is peer-reviewed? | |
| when do you replace capacitors? Smoffatt the thermal grease is not an insulator in case you got that from Minorl's comments. But if it is dried out, heat will not transfer and so the transistor can overheat and possibly short.The best kind of grease is white. There is a clear va... |
