| New op amps, good idea? I just converted the output stage on the low frequency EQ unit for my Infinity RSIIb speakers from cap-coupled single-ended mosfet to direct coupled with OPA827 opamps, and the new output stage is much more transparent and clear sounding. The enti... | |
| Is PS Audio powerful enough for my system I run my Zero One Mercury CD/HD player, Supratek tube preamp, and two Gilmore Raptor 500WPC monoblock amps with a PPP with no problem whatsoever. The fan doesn't even come on. I tried the amps directly from the wall and it does not sound as good a... | |
| How do Zu Libtech & Kimber 12TC compare? Have the Zu Ibis, not Libtec, but they are so good I don't even think about changing cables any more. Great bass, mids, treble - everything. Get them used if you can and save a bundle over new. | |
| Will Graphene replace Mylar? Will Graphene replace Mylar?That's the wrong question, I think. Mylar is simply the support for the conductive aluminum layer in a planar driver - since graphene is as conductive as copper and as strong as steel, there will be no need for the supp... | |
| Capacitor log Mundorf Silver in Oil Yes, in most designs the last PS cap is in the signal path, because the signal path is not isolated from the PS current path. The PS caps are still there in a parafeed type design, but they are isolated from the signal path by the circuit design. ... | |
| Capacitor log Mundorf Silver in Oil Of course you can always convert the amp to a parafeed-type configuation with a CCS or choke on the plate instead of a resistor and eliminate the PS caps from the signal path completely. That's what I did with my preamp and the results were astoni... | |
| Tube Preamp for Solid State Monoblocks? My only watchout would be impedance matching. Some of the Class D amps have a low input impedance (8-10K) and there are tube preamps with output impedances in the 1000s - those would not be good matches. Try to keep a minimum ratio of amp input im... | |
| What Speakers to use in a bar/restaurant environment Over the years I've seen a lot of bars with Bose 901s hung from the ceiling. They go loud and are pretty durable, and you can get an older system fairly cheap nowadays. | |
| Supratek Chenin or Cortese My Chenin has been very reliable, even after I have made all the above mods to it. Not one single problem, ever.Some folks get put off by the point-to-point wiring job in the Suprateks; it is a bit of a rat's nest, but that doesn't seem to be a re... | |
| speakers close to the back wall ? Oops, I thought you said around $300. The A400s are WAY below your budget! | |
| speakers close to the back wall ? Boston Acoustics A400s are made to go close to the back wall, and they are in the same ballpark as your budget. Disclaimer: I have a pair of these for sale currently on Audiogon, but this post is for information only, not a sales pitch. | |
| Infinity RS 1b the one with 4 Towers - Recommend? KEEP the RS1b's - you can make them into world-beaters with some modifications, if you are up to it.Here is a thread from AudioKarma where I ("Maxamillion" over there) go step by step through the modifications I did to my RSIIb's which have turned... | |
| How do I improve a room with a low ceiling? Some folks just attach fabric across the ceiling joists to give the appearance of there being a ceiling, but the fabric is acoustically transparent, giving the sound of a higher ceiling. You can then choose to stuff the area between the joists wit... | |
| Supratek Chenin or Cortese I have a Chenin (2006 build) and I must say that it is an excellent platform for modifications. I have done several modifications to the unit and I believe it is now the best sounding preamp I have ever heard. Here is what I did to the linestage (... | |
| Optimizing Magnepan MMGW On Wall Speakers I have the slightly larger MGMC1 speakers in my living room, where they provide party music and background (main system in family room with honking big Infinity speakers!). They sound very, very good for their size and cost. They have the quasi ri... |
