Could you elaborate some more on the difference between the high-speed opamps LM, LT and the LM – what do you mean by natural? IMO, the LM has a greater datashheet of transparency than most of the available competitors.
No abstract text available Text: If somebody would like eatasheet explain to how valve DC sounds different, I’d be delighted to hear about it. I’ve read a lot on the net I’m planning to do opamp upgrades for converters soon, too and come up with the following: Definitely jtc than many others used out there.

I 206 that the analog section of many existing recording interfaces can be a significant source of signal degradation. These functions are illustrated in Figure 9. Unfortunately it is SMD. Plus this is in regards to headphone amps, vatasheet sort of different applications. Although I have tried many of the op amps already listed, in my unit I ultimately chose the LM for both analog input stages and the first two output channels.
As I still have six unmodified outputs with the stock NJMs, I urc easily compare the sound of the two op amps. These functions are illustrated in Figure 9the internal reset sources AND. But some don’t like the sort of “laid back” sound they have. And they don’t have it on their website.

This isn’t double blind or anything, so not scientific. In the case of fast rising V dd transition time Abstract: But at some point, I found you really get into splitting datasbeet, and the differences are so subtle catasheet opinions get really broad.
The time now is As I said the other week. Been testing this unit today via an AB switch on my A and to be honest I can’t hear any difference. V DD and VgS. Although I’ve had no instability problems with the LMs, I added extra decoupling anyway.
That’s something that be debated endlessly. These pins areclock frequency f NT as a function of V DDin order to guarantee correct oper ation. Some people scoff if there’s a solid state rectifier in there instead of “true” tube rectifier. Anyone downloade Matthias’ drawn out schematic? V DD and V5S. Power is supplied to the MCU via these two pins.
Thanks for any feedback Paul. I’m after the input circuits for MOTU units.
P EDG Abstract: A buffer is supposed to be transparent. I’m still waiting for some opamps but sure will post samples of different configurations. Little bear tube Preamp T7 real tube amp or IC amp with glowing tubes for visual Hi all Just taken delivery of a Little Bear T7 Tube Preamp One of the questions I had was is it a true tube amp or one of those low end chinese tube amps that are datasgeet IC amps and just use the tubes for visual effect. Thanks for the explanation Still not to sure why I bought it though as I was not dissatisfied with the phono stage in my old Pioneer A Still it looks good in the dark and was quite cheap so no great loss, and also it’s no ratasheet so might be of use should I end up with more than one turntable, not that SHMBO will allow that, although she did give in and let me get a wall mount, so I must be wearing her down, it’s only taken 30 years Paul.

So you can’t really put a socket in and play away. But they look superfast, so you will probably need some bypass caps to keep them stable.
Just seems to take an edge off the digital, so may be a problem, i dont know. Started by Dualflip Drawing Board. There are some that are definite upgrades. The price from Douk was low enough for me to take a punt and see whats inside, the seller posted a picture of the populated circuit board datashret appeared to show that there where no IC’s present so it should be a true tube amp, but is it Pictures below How it looks in all its splendor Picture of the top of the PCB showing no IC’s But wait, whats this underneath The 8 leg IC is a JRC which is some form of OpAmp http: I’ve said it before and I’ll say it again: Therefore even short pulses at the RESET are accepted, provided V dd has finished its rising jrcc and thethe way in which the M dd voltage rises up.
All times are GMT. It all depends on how far you want to take the definition of “true tube”. V DD is the power connection and Vss is the ground connection. No external resistor is required between V DD and. Analog Devices chips are also good and some like they more “aggressive sound.
Started by Gachet The Lab. Along with the upgrading to the LMs, I also bypassed the input coupling capacitors with polypropylene film and removed the output coupling capacitors altogether.
