Doug Schroeder Method, Double ic

Even my wife says she doesn’t understand me.......My thinking is that the cable from the turntable being the oldest of the Schroeders has reached a higher level of performance because the new ones (from the CD player) are still opening up. At this time, the CD player is not what I think it can provide in sonics. With my older silver cables, the turntable sound was better in some ways than the CD player, and the CD player was better in other ways....all depending on the recording. Also, all sound is going via the long preamp to amp new cable.  Of coarse, I’m open to any of your suggestions. ...just as an aside, I’ve played the Purist Audio and Ayre break-in discs but without any progress.

Douglas, the speakers I use, Franco Serblin's Lignea  have minimum impedance of 7,9 ohm, so I have them conected on 8 ohm outputs. I do not think (correct me if I am wrong), that conecting it on either 4 or 16 ohm outputs would be helpful. Perhaps it would be interesting to know if all the people who do not hear the positive change have the similar sounding experience and on which kind of gear

alexatpos, unless there is a reason to take caution with operating a particular speaker on the other outputs, I make it a point just to see what the resultant sound is like to try speakers on all amp outputs, i.e. 4,8,16 ohm. The results can be surprising, and often I prefer one setting that is not aligned with the minimum impedance of the speaker. You will definitely have a different result with each of the outputs. One might be superior. In many instances speakers that were rated 8 Ohm sound much better to me as the 4 Ohm outputs are used. One simply has to try in order to determine which is holistically superior. My point was that it may help to isolate an influence why the double IC is not to your liking. 

Stringreen, if both of the Schroeder Method ICs are similar type, ie. XLR, you could swap the short one with the longer to see if there is an immediate degradation due to the length. Set up the rig and get used to the sound again at baseline. Then swap the two double ICs for comparison. Could be interesting. 

Douglas, speaker outpus on tube amps are not exactly correct. It is generally known that factorys declare a ’middle’ impedance. The lower the impedance of the nominal is the bigger problem, so the transformers are counted with that in mind, typically the 4 ohm output is calculated for about 3.2 ohms and 8 ohms for 6-7 ohms. So, one level of flexibility is already included in any construction. 2) The operation of the speaker impedance above the declared on the amplifier increases the damping factor, decreasing the output power and distortion - until the moment of clipping. Working with lower impedance reduces the output power but also increases distortion. Having all that in mind, I prefer to stick to predictable solutions (right output for known impedance)
But, thank you for your advice, I do believe that is important to have an open mind, more so in audio, because there are lots of things that laymans or even experts cant explain and yet they are audible

doug - do you plan on reviewing any of the Exogal Vortex streamers ? Simple yes or no will suffice . Thanks,mike
