Tube or not to tube?


I am new to the hobby and would like some input. I am seriously considering moving to a tube-integrated amp (new or used)like the PrimaLuna II or the Jolida 502. Currently I have the NAD Combo 162/272. Would I be upgrading my system with either of the tubes? Or am I just moving sideways?

IMO, you should have no problem driving your Emma loudspeakers (86db/1w/1m, 8 ohm minimum) with a Prologue 2 or similar push-pull tube integrated as long as you are listening at moderate volumes not exceeding 95db.
Tube amps don't require herculean efforts nor advanced degrees, but they do require one to use sufficiently appropriate speakers in order to achieve a listening experience that goes far beyond what you've experienced with SS, though many would disagree. It's the best audio move I ever made, and I don't intend to return to SS. Lots of nice amps available, so do some web research, do some Googling, check out some of the Audiogon virtual systems.
if I do try a tube amp like the Primaluna can I use my NAD 162 pre-amp? cd player and turntable connection.

I'm not sure I understand the question about being able to use your CD player and turntable connection.

You can certainly use your CD player with the Prologue 2, and if the Prologue 2 has the phono card, then you can use your turntable.

Since the Prologue 2 is an integrated amp, then you don't need to use your NAD preamp. Whether you can use it if you choose to use it is not a question I can answer. I suggest you look at the info on the Upscale Audio website.
Sorry, I was looking at the prmia and the joida and I did not see either had a phono input. Just a cd,tape, aux. I do have a nice collection of lp's (IMO), In my wed surfing I have come across tube imtergrated amps need a per-amp for phono so, If I come across a unit with just an aux input can I use my current pre-amp?
