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?

Check out the Cayin line. Incredible build quality and looks with magical sound to match. It should be a very dramatic improvement over your NAD given you have ample power.
If possible, try to audition one or two tubed units versus a couple of solid state units before you make a final decision. The "tube heads" usually respond strongly to posts like yours, and I have no particular quarrel with them -- our hobby IS about choices and personal sound preferences.

There are strong points that can be argued for both tube and solid state, and the best of each type sound increasingly alike (the better aspects of tube, plus the better aspects of solid state reproduction). To an extent the "best choice" will be dependent on three pertinent factors: the loudspeakers you will be using; the other audio gear in your reproduction chain; and your room acoustics (maybe the MOST significant factor.

In my earlier years as an audiophile, I owned tube gear (Fisher, Marantz, H.H. Scott, etc.), but in the late 1980's I made the switch to solid state. I have not regretted the decision (although, as you will note if you look at the description of my system in the "virtual systems" section, you will see that I do have a pair of Musical Fidelity X-10 tube output buffers).

As a point to consider, you might be interested in a conversation that I had recently with one of the owners of Definitive Audio (the oldest and largest high-end audio dealer in Seattle). He said that Definitive Audio carries very little tube equipment any more, and that he has replaced all of the tube gear in his system with solid state. The specific reason he said he made this decision (for both the business and his own system) is that there are relatively few manufacturers of vacuum tubes, and that quality control varies rather widely (which makes it more expensive to select only the best performing tubes).

I am not trying to "sell" you on tubes or solid state -- simply urging to get more information on the pros and cons of each, and do some extended listening before you make a buying decision (preferably with in-home auditions).
Musicrover, timing is everything. Check the classifieds under tube integrated. I am selling my Audion Sterling. It slays the integrateds you have mentioned, plus I am including tubes to die for. Check it out. It's a great deal. peace, warren
