| Do preamps have a material affect on high level sources? Only when going direct isn’t possible without "bit stripping" or if the source has no volume control, are passive pre’s the next best in line for transparency and dynamics, and yes that includes my one sunshine. And not once did I mentioned mine i... | |
| Looking for great tube integrated for Martin Logan Summit X speakers Do I have to have speakers attached if it's on? Solid state amps can be powered without any load on them. But tube amps need to see a load, as there is the possibility without a load they can damage the output transformers if they go into oscil... | |
| Do preamps have a material affect on high level sources? Yes that's fine, good quality ones are lower than 100pF foot. Only if you've crap interconnects with high capacitance and over 4mt, does so called "driving the cable" become an issue As I said it's something manufacturers of active preamps have h... | |
| High resolution digital is dead. The best DAC's killed it. so what’s your point? Take a pill sunshine. I said That the DS PRO PRIME was part of the "DS Pro" series and it was the only one of 9 in that series that was Delta Sigma, the rest all being R2R. I don’t know what gen Cassanova i was holding And t... | |
| Do preamps have a material affect on high level sources? vjpacor Dac’s with passive analog volume controls in their outputs, and interconnect interaction, is a bit of a furphy. Most good quality interconnects are much less than 100pF (picofarad) capacitance per foot.EG: Say you have average quality cabl... | |
| Do preamps have a material affect on high level sources? But why then, isn’t it common to drive a power amp with the variable analog output of a good DAC? There aren’t that many around, most are done in the digital domain.But if you do have one it’s still fine, what you've got is a passive preamp but i... | |
| High resolution digital is dead. The best DAC's killed it. And all the DSPro’s from Gen 1 were R2R Sorry, but the Pro prime was only one of the Pro series to be Delta Sigma it used the DS chip SAA7350GP. The Pro Prime II was not DS it had 2 x PCM67P-K R2R chips In fact, in 1994 i don’t think there were s... | |
| Do preamps have a material affect on high level sources? vjpacor It would seem that a preamp is merely attenuating a DAC output. How can it alter the signal? The fabled perfect "active preamp" sound, has the "the sound of a piece of wire" and it does not exist. Any active amplification circuit, whet... | |
| High resolution digital is dead. The best DAC's killed it. FYI, I had occasion to speak to the guys at Theta about the Casanova recently. According to them the DSPro is significantly better. That's because all the 8 "Pro's" (except for the Pro Prime which was DS ) were all R2R and for PCM Redbook i... | |
| High resolution digital is dead. The best DAC's killed it. The Theta Casanova from memory used the same dac chip/s as the Casablanca which had hybrid PCM-1792A converters in it, few bits of R2R and Delta Sigma mix, it was the time of the transition period from expensive to produce R2R converters such as... | |
| Question About DACs The fact is I don’t belive That is your belief, and your entitled to it. | |
| Looking for great tube integrated for Martin Logan Summit X speakers "George and others, what should I listen for that will show me the limitations of tubes with my speakers? As I said above a tube amp that’s a good design, but doing it hard into this load of the Summits. The hard load is at:At 5khz to 20khz may s... | |
| Looking for great tube integrated for Martin Logan Summit X speakers I have owned a Primaluns Dialouge 1 Intergrated It drove my KingSound King Electrostatic pretty good in a smaller room . My speakers should be harder to drive than your ML . No sorry it’s the other way around.ML’s https://hometheaterhifi.com/w... | |
| Question About DACs The fact that George says R2R Multibit is bit-perfect and D/S DACs aren’t is just nonsense. You need to read an learn a bit more. PCM is converted more "bit perfect" with R2R than with DS | |
| Question About DACs Haven't heard those two, but the Yaggy is very good and they all come from the same stables. Schiit's Mike Moffat the designer is no slouch, he made Theta Digital no. in dacs when he was with them.Cheers George |
