Best Preamp - NO preamp... (?)


A few hours ago I decided to experiment and bypassed my highly regarded, excellent passive preamp and hooked up my PS Audio DSD DAC directly to the power amp.
There is no going back...
Every aspect of the sound has improved so dramatically that I'm simply blown away. I'm a bit shocked, playing CD after CD and I still can't believe it.
My phono stage has gain control as well, so it seems that from now on it will be disconnecting RCAs and plugging each in turn.
Since I usually do vinyl day or cd day (or week) anyway, the trouble seems totally worth it. Letting the cable settle in for a bit is not an issue.
Am I just crazy or are any of you doing the same?
Should I be concerned about damaging  the RCAs over time?
Thanks for your thoughts and experience. :-)

Thank you all for your thoughts.
I totally get it that it's always a personal preference, and depends on component output level, input gain, and impedance matching.
Some DACs don't even offer a variable gain output so for those it's not even an option.
My amp is a very low power Yamamoto A08S so I use the volume between 70-100% anyway, no 'lost' resolution issues.
Other than the need to match gain or impedance, I find it hard to imagine how having the passive preamp in the signal path can make things 'better'.
It makes the signal pass through additional connectors and IC cable, internal wiring, solder points, input selector, and volume control. The passive preamp I have is considered one of the best you can get at any price point, and removing it from the signal path had such a profound positive impact that I still can't believe it's even the same system. Active preamps should be worse in that regard, no matter how good they are, as the signal travels through many more components. 
I had a friend come over last night, who is very familiar with my system, and he too was shocked what a difference it made, He texted me this morning that he couldn't sleep last night after hearing my system, and is now thinking of selling his excellent gear, and getting the exact same setup as mine. I must be very lucky to find such a perfect match :-)
I still need to check how it works with my phono stage, but my TT is going for service this week. I honestly think that even if it doesn't work well, I will be looking for another phono stage that does work well, and will not even consider putting a preamp back in the system.
Highly recommended everybody - Give it a try!

I think my point for discussion is actually better phrased this way:
Instead of looking for a best (objective) match between 3 components, source-preamp-amp, perhaps we should be looking for the best direct source-amp match, eliminating the preamp altogether. Unless you need multiple sources of course.
This should be an overall easier task as way fewer combinations are possible, and the potential benefit is much higher as the signal path is significantly shorter.
For gain / impedance matching, a simple resistor divider network can do the trick instead of a full blown preamp...
I know there are decent RCA and XLR attenuators out there for sale.
If you need the gain boost that an active preamp provides, wouldn't you be better off looking for a source with higher output, or an amp with higher gain?


I know people like to torture themselves.
Diving underneath your rack and taking off one set of plugs, hooking up the other set of plugs to switch components seems insane and unnecessary.
What you're explaining indeed is you simply got rid of passive preamp in order to use active line stage of the DAC or phonostage.  Active drive is almost always better because tonal balance is easier to achieve in almost any volume setting... So my solution would be finding inexpensive active unit such as Cary AES or McCormack RLD would bring you even to higher performance level than you having with your current source units.

Thanks for your input czarivey,
Fortunately, my power amp is so gorgeous looking with it's Japanese cherry wood finish, that I have it on the top shelf of my rack (also for better heat dissipation of course :-). Therefore, changing the IC cables is very easy and convenient. I don't even have to bend.
My DAC has only one output, and all I did is disconnect it from the preamp input, and hook it up directly to the power amp, so I was using the same active line stage in both cases.
I don't understand how adding another active component in the signal path can make things better, but i'm always open to learn and experience.
I tried a few highly regarded preamps before, and my passive outperformed them all.

Ami,

I am also using my PS Direct Stream sort of direct. However, I have my Direct Stream first going to the BSG QOL and then to my Pass Labs Amp.
