To preamp or not to preamp. That is the question.


I have recently set up a second system from some previously owned components which I though I would use for occasional listening as I have a better rig in a dedicated music room. Yet I find I'm listening to it more than expected and want to optimize it.

I use only a single source, a Bluesound Node 2i, feeding directly into a Forte 4a Class A power amp and some Totem Model one signatures speakers. No preamp! Controlling the volume with the BlueOS app, the system plays loud enough for my listening needs but I know the output of the Node is on the low side for the power amp. I'm not looking to upgrade the current speakers, amp or streamer. Other than having more gain, would adding an active preamp bring anything to the table other than more expense and additional "stuff" in the audio chain. What has been the experience of other members been who have gone this route?

I’d be hard pressed to think a good preamp wouldn’t make a major improvement over using the Node as a pre. If you were using a Bricasti and its volume control I might have a different opinion, but using the Node as a pre? No, just no. The Node 2i is a streamer, DAC, and preamp for $600 — using common sense, how much do you think they spent on the preamp components?  The preamp is too important to the overall sound quality of a system. FWIW, and best of luck.

Any time a component can be eliminated from the chain the result is better sound!

Not if the output of the device is a mismatch. Bluesound Node 2i is designed to plug into a preamp, a preamp is designed to plug into an amplifier. The signals a preamp is looking for is different than what an amp is looking for. Can it work without a preamp? Often it can, but in most cases it is a better signal match if plugged into a preamp/processor. 

Not heard a Node 2i but own a Vault 2 which probably sounds close enough. The Bluesound is a fine device for the money but the DAC is the weak link. On its own I would not recommend bypassing a really good preamp. If you’re considering a preamp I would recommend looking for a standalone DAC with preamp and use your Node just as a streamer which it’s very good at. I use a RME ADI 2fs and go direct to my amp which sounds great. Unless I’m spinning vinyl my preamp stays out of the chain. 
 

If you’re using the stock power cord on your Node look for an aftermarket as for little money it will improve things. I built my own purchasing parts from VH Audio but many on here recommend the Cullen C7.

An intelligent and rational observation. Yet don’t you realize a preamplifier no matter how accomplished is merely adding “noise and distortion”? 😊

I’ve tried it both ways, two different times, and each time I decided to keep the preamp. I use a Cambridge 851N streamer/DAC feeding a Bel Canto PRE5 to Bel Canto ref500 monoblocks, driving Dali Mentor 6 floorstanders. With the preamp in the system, I believe I heard more of a difference when switching from Morrow MA5s to Kimber KS1116s, both XLR. Both sound excellent but I felt more of a difference between them with the preamp in the chain. What I am sure of is that the sound is better with the preamp in. specifically the opening notes of A Chloris: A Chloris, track one on A Concert at the Time of Proust. The period instruments (piano and violin) are just more real with the preamp in the chain. No contest.
