I am considering purchasing an iTube2 and need advice. I know a dedicated 2 ch preamp is considered better for music than an A/V preamp. I use a Marantz 7702 A/V preamp with Paradigm Active speakers in my HT. I use a Sony UHPH1 bluyray player as a source. The Sony plays/streams every type of file there is and has both HDMI outs and RCA outs.
I can install the iTube between the Sony RCA outs and the Marantz 7702 and use it as a buffer.

I can also use it as a preamp directly between my Sony RCA outs and my Paradigm Active speakers.
You can see the pic below the speaker has both XLR and RCA inputs. My Marantz uses the XLR and I could run the iTube directly to the RCA's and use as a preamp.

Should I use it as a buffer or as a preamp?

Any advice would be appreciated. Thanks

My suggestion, buy one from Music Direct and you have 60 days to evaluate it. The best way is to try it in your system and see. If you do not like it, return.

Thanks. Does anyone have an opinion of how it performs as a pre-amp?

I found the SQ as very good.

Thanks, how did it compare to your current pre? I I like the idea of an audition period.

I have never used mine as a preamp (has I think just 9db of gain).  I initially had it as a buffer on my (main) computer system between the computer and a beefy old Onkyo 1008 receiver (which I bought for a secondary basement system in my old house and then used in my main system and then when I upgraded the main system receiver I moved it to the office and after lightning damage I moved the Onkyo into my master bedroom system and bought a NuPrime IDA-8 for the office system).  I've had it as it is now in a couple of systems between a outboard DAC and a preamp input as a buffer.

I'm not sure I understand the goal. Yes, the itube 2 can be used for either purpose, buffer or preamp. What are you looking to gain by adding the device?

I know the Marantz may not be "audiophile purist approved" in comparison to a dedicated 2 channel preamp, but it's still a very nice unit and I would think that its room correction capability is a boon in HT and 2 channel in your modest setup. If anything, adding the device in the manner you're looking at is just adding another point of unnecessary insertion loss. Nonetheless, it's worth giving a try even if just to satisfy your curiosity. You have nothing to lose and experience to gain. Very nice, modern classic, speakers by the way.

You can read all about it on the iTube2 tour thread.

Reviews start on page 4. (I'm on page 6-8 and talk about all the differing switching possibilities, 3D, as pre-amp/buffer, etc.)

I want to see if an itube used as a pre-amp can "lift any veils". The signal path should be shorter than my marantz for two channel as a pre-amp. Bob Carver is a designer I respect and I listen to his passion about tubes it makes me curious enough to try it. I don't feel I am missing anything BUT you don't know what you don't know.

Nice thread, StevenZ shared good feedback on using as a preamp. Gotta read the other posts, thanks.

Oh, I see. I wasn't clear if you were going to use the iTube in place of the Marantz or still keep it in-line. Either way, give it a try. Typically adding a device(used as a buffer) won't lift veils though. While I once owned the iTube 2 and think it's a great device for the price, it is not the most transparent (veil lifting / revealing) preamp. It could possibly be better than your more complex Marantz though. Give it a shot.

Ok for desktop stuff, did not like it in the big rig. It did not make things transparent.
In fact it added too much. Listen for yourself. I like to keep things simple.
