Dual mono passive Pre amp, single ended (advice)

I'm not sure if that means you're baffled or annoyed or something else. Care to clarify?
BTW, what were the pre-amps you compared when you chose the LDR?

It
Doesn't mean much mate, I was just imagining my Hifi sounding like a 197"'s tv. I know that wasn't implied, but I found it quite funny.
I compared the LDR with a Croft Epoch, Expo, Naim and DIY class A Pre amp.

Perhaps I should mention that I'm actually a big fan of passive pre-amps. Some people say they lack dynamics but I have never found that to be true.
Anyway, it's interesting that you chose a passive pre-amp in preference to four other pre-amps, all of which were active. I probably would have done the same.

Quite a few years ago I let go of an Expo II/IX, back then it was by far the best pre amp I had heard. Maybe I look back fondly with rose tinted glasses but I would love to hear that combination again in the system I have now.

Hehe i love this forum, i suppose we should add it to the list of great british debates

Rolls or Bentley
Rich tea or Digestives
Cola cubes or pinapple chunks
Roast lamb or Beef

Everyone has there own tastes and wont be swayed, thats whats great and frustrating about this hobby,

And the end of the day ya likes what ya likes

I'd be interested in trying the LDR when it makes its rounds. I run either a rotel rc850 or a DACT diy passive so it'll be an interesting comparison.

I have been playing with a few passive preamps recently and getting interesting results. I really like the Khozmo passive preamps. They are very well put together and use high quality resistors. If you are feeling flush then they make an up-market version, the Hattor. It comes in a really natty box, has very high quality resistors, remote control, balanced input/outputs and is remote controlled. It sound is among the best I have ever heard. It has the dynamics and bass that some passives seem to lessen.

I have tried a lot pf TVCs and their quality seemed variable depending on what I used them with. The music First copper did not work so well with the Audio Research Ref 110 so I bought an ARC Ref 3. The Townshend Allegri did not work ideally with a balanced only input Class D but was a real stunner with a Naim. The Townshend was not as good as the Hattor with the Nord Class D.

Never tried LDRs. Do they need to be re-calibrated every so often as the resistance changes with age, for the same amount of light? Could that impact the balance at low volumes??

No if designed properly.

There is misconception I think again here with comment like, "the same amount of light" with the construction of LDR's

The type used to act as sensors for street lamps and ovens and many other purposes, are open face types, are NOT the type used for audio purpose circuits.

An image of each clarifies, they are entirely different devices.

First the open faced type, one would be very silly using these in audio circuits, as they are typically used as a fairly primitive switch.

When the dedicated audio purpose encapsulated type is available
with well published resistance ON and Resistance OFF figures. The NSL32SR3 being one of the best available
capable of varying resistance from 60 ohms to well over 20 mega ohms, IMO

is there a forum where no manufacturers are allowed to discuss with normal people.

i fancy a change
