Any thoughts on removing a preamp from your system


Hello guys

This is my first post and I have been on Audiogon for a number of years now.

My question to the group is, have any of you removed your preamp completely from your system? Run your front ends straight to your amp? And, what benefits have you noticed, if any.

And finally, if you have used a passive preamp in your system, what are your thoughts on the setup?

I understand one would need to have some sort of "pot" in the signal path to regulate volume.

Hello Herb, I have tried to remove a preamp from my system several times over the last 20 years or so. Either by going direct from source to amp or using a passive control unit. Basically, all I really learned from my experimentation was just how important a preamplifier can be in the overall sound of a system.

I have found that preamps can be the most difficult part of a system to get right, but when you do, it's stunning, as Alan (Arh) has also noted. At this point, I do not plan any further experiments without preamps, in fact now I believe the preamp to be the heart and soul of the system. As usual, YMMV.

YEs, but the question is, why?

I can see how the proper eletronic mating might be trickier with a passive, but I cant see a disadvantage if done right

I can't see sound waves either, yet they are there. My ears tell me the difference, not my eyes. I can't explain why anymore than I can explain why a power cord can make a difference, or tubes sound better to me than solid state.

I'm sure that someone can probably come up with some techno-marketing buzz words that may help you understand why, but in the end, all the proof you should need is in the listening. Trust your own ears.
Herb, several times during my passive experimentation days, I too heard greater transparency when using a passive unit or going direct to amp. I am familiar with this feeling. The key is will this feeling last? I've found that after a period of time listening to this newly found transparency, when switching back to an active preamp, I rediscover the weight, body and soul of the music which had been lost during the switch, and was not initially realized during my enthusiasm for the gained transparency.

Overall, not just with preamps, I've learned that musicality is more important to me than transparency. If tonal accuracy is not true, I do not care how clean the signal is. This is the same reason I've given up on Nordost cables. Their transparency and revealing qualities can be very enticing in the beginning, but I've found, over time, that they cause me to listen less often and for shorter periods of time as listening fatigue sets in sooner and sooner. I still say that Nordost cables are great for demos, they will impress your friends, but I just don't care to live with them over the long haul.

Obviously, others will have different goals, but my days of chasing after the ultimate in resolution are over. I'm more about listening to what sounds musical or natural to me these days. My system is not as resolving as it was years ago, but it's much more enjoyable to listen to. I wouldn't say that you are imagining the increased transparency, I would just say be cautious, as this new sound may turn on you down the road.

Cheers,
John
