What amp do you use with your passive pre?


I decided to get a LDR Passive Pre. No, not Tortuga. This one is from a super nice guy name Chris in New Zealand. I currently have a Class D amp (one of those better boards). Although I like it, I always miss the Class A/tube sound. So, looking for amp that is minimum 50wpc. I currently have 91db speakers but will change them soon to Harbeth (most likely).

Long story short; what amp are you using with your passive pre?

OK let me try to clarify few things in my mind.
I assume every amplifier manufacturer gives the input sensitivity
I’ve only ever seen the input sensitivity (in volts or millivolts) for amps as stated for the amps full wattage output just before clipping. Unless specifically stated for only 1 watt of output

Speakers sensitivity (where you maybe getting confused) is stated as sensitivity in dB for for 1watt input .

@georgehifi no not confused with dB. 

So, unless stated like First Watt J2, it is always stated at full power?
Yes with poweramps, input sensitivity is usually stated as the maximum voltage input, at which time the amp is just below going into hard clipping usually into an 8ohms load.

Cheers George
The wording is usually something like "at rated full power". You could directly drive most of the amplifiers in the market with a 3 volt output from your DAC.
