Comparing Phono Pre-Amps

Oh Boy, here I go...

Do you all feel there is a easier way to compare Phono Pre-Amps besides connecting/disconnecting each one?

I have thought about if there is a way to take the output from a TT and send it to 2 Phono Pre-Amps and from there, those 2 pre-amps could be connected to an Integrated and from there, you simply switch back and forth?

I have been looking but have not come across such a device.

From what I have researched, most comments have stated to simply have long listening sessions with both back and forth and I get that but wish there was a ability to switch immediately between two.

I know the thought is doing so would introduce all kinds of unnecessary variables that would ultimately degrade the sound and defeat the whole purpose.

But I guess from a technical standpoint, can it be done?

Thnx

This might work — hook the input pair to your turntable and the other two output pairs to your two phono preamps.  Hook each phono pre to a different input on your stereo preamp and just switch inputs to compare the two phono pres.  You obviously need two pairs of stereo interconnects to hook up both phono preamps to your stereo preamp, but you might have those on hand and if not they’re obviously easy to find.  Best of luck.

I wouldn’t recommend splitters. They may introduce more uncertainty into the equation. 

 

I want to reinforce the idea of long comparisons. A few quick swaps will tell you if there are any huge tonal differences or detail differences. But long… I recommend at least a week listening to music (not the system)… two is better auditions… then switch. This will allow you to understand the sound much more deeply and make the comparison. Typically, taking a lessor component out is where the real moment of understanding comes.

Thanks for the suggestions.

I think I might try the cable route.

For the ground, can I simply send the ground to each phono-preamp or just to 1 one of them?

This really is just for comparison reasons not a permanent solution.

Thnx
