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?

While I agree with the previous post about the types of preamps that exist, I don't think the $15K price point for No. 4 is necessary.

I have built tube preamps and bought tube preamps and I have rarely spent more than $6K. Particularly, if you search through the quality Used market. A well-made tube preamp should last for many years. Tubes can be rolled/upgraded at will.

In fact, I currently have a PrimaLuna Dialogue Premium tube preamp that was less than $3K. Tube rolled in some NOS Mullard 12AU7's and pushing an NAD M23 SS amplifier. Truly a wonderful sounding system, with a wide soundstage, a bit of warmth, with the minimal distortion and solid punch of the NAD.

to keep it simple, same number of pieces, perhaps change to an integrated amp (includes preamp) with remote volume and any other desireable features.

you keep the existing amp available for ... or sell it.

Thanks for all the wonderful input. I am fully aware of the limitations of the DAC in the Node 2i as agd 101 pointed out. It's serviceable but not great.

On my main system my upgrade path was Node 2i , then node 2i with a Musician R2R Dac, then Lumin u1 Mini with Musician DAC. The Node was put back into service with this recent second system. 

Lordmelton pointed out several options. Since I do need more gain, option 1 and 2 are out. No doubt a good tube preamp brings much to the table and in my main system I use a Conrad Johnson LS17 line stage into some Quicksilver Monoblock Poweramps.... so I get that. However, with this second system, I want something rather less costly with a smaller form factor due to space/cosmetic considerations. Also I need a remote control. And so I will likely try something solid state, and see if it yields any improvement. There seems to be enough opinion here to support the fact that a preamp will improve things

What is budget for the preamp?

If you think your preamp is adding quality to the presentation, where is it getting it?  I like to look at the signal path as 100% as digitally stored on the medium.  Every time you touch it to DAC it, to preamp it, to amplifty it, you try not to degrade it.  

I'm a minimalist when it comes to signal path.  Great tube amp designers agree.  I use my DAC is my preamp (since I listen only to digital signals).  

Keep it as simple as possible.  

DAC is Chord Dave.
