What’s the difference regarding high end detail, transient response, perceived proximity, the perceived “immediateness” of bass? Southall, West London Posts: I think they would be an upgrade. datasehet

If somebody would like to explain to how valve DC sounds different, I’d be delighted to hear about it. So the daatsheet for those in the know, is is it a true tube amp or is that OpAmp really doing the amplification.

These functions are illustrated in Figure 9No external resistor is required between V DD and the Reset pin, thanks to the built-in pull-up. BB, are favourite replacements.

Been testing this unit today via an AB switch on my A and to be honest I can’t hear any difference. If you have an impedence mismatch between units then it should sort that.

Datassheet read a lot on the net I’m planning to do opamp upgrades for converters soon, too and come up with the following: So you can’t really put a socket in and play away. No external resistor is required between V DD and. They are pretty stable and are very flat.

Anyway lots of options. With a quick search it looks like the op-amp is the phono amplifier stage and the tubes are the ‘valve buffer’ stage after and for the AUX function. I’ve done more reading and the LM seems to be the way to go.

Some will impart a bit of a signature too. Some people scoff if there’s a solid state rectifier in there instead of “true” tube rectifier. Another chip worth looking into is the AD, which is a dual related to the AD, but doesn’t seem to have the latter’s stability issues.

But some don’t like the sort of “laid back” sound they have.

Analog Devices chips are also good and some like they more “aggressive sound. I haven’t done the changes myself yet, but from audio examples I have heard this is definetly worth it.

Along with the upgrading to the LMs, I also bypassed the input coupling capacitors with ratasheet film and removed the output coupling capacitors altogether. Gachet Member Bordeaux France Posts: V DD and V5S.

They speak of the OpAmps being the biggest weakness. That’s something that be debated endlessly. Not complaining Regards, Grant Anyone downloade Matthias’ drawn out schematic? You may also want to consider bypassing some of those caps with 1uF film caps as well.

Some regard it as a warm valvy feel, but thats just imo smearing due to poor design and parts.
