Cary Audio SLP-05 or Conrad Johnson ET7 S2


I’m not in a hurry to add a preamplifier to my existing system which consist of a Brinkmann Nyquist DAC and a Decware 341.5 tube amp.  But…I do have the itch.  I’ve searched all over the net for reviews and comparisons but did not find anything persuasive.  I will purchase used and on Audiogon, each is available at around $6500.  Any guidance would be appreciated.

@avanti1960,
I was not aware the Cary SLP-05  has that degree of gain range flexibility.  This allows it to be compatible with practically any power amplifier. I wonder why this feature is not available with more preamplifiers. Total audio system gain is an issue that has to be accounted for.

i would suspect the answer would be cost, complexity, and potentially, slight sacrifice in sonic purity as a result... but i totally agree that gain and impedance matching is critical in a system of disparate components, so the flexibility afforded by the cary design is a definite plus
I had a Rogue Audio preamp with 3 levels of switchable gain 3, 12 and 16db.  
this proved to be very useful too.  
Taking the gain out of the equation led to a better sound to me, max it out.  Then play with the control got volume.
