Pairing older NAD power amp with newer preamp

Great. I'll check it out. Thanks!

Almarg, I checked out the Antique Sound Lab Line Two DT as you suggested and I will give it serious consideration. Another I have been eye-balling for a while is the Vincent SA-31 tube/ss hybrid pre. It made the Absolute Sound's Editor's Choice list. Owner's commenting on the Audio Advisor web site are quite pleased. It's also $300 dollars more than the Line Two DT but includes, good or bad, more circuitry...tone controls, tone deactivation, loudness, led power light. It uses two 6N16B tubes vs a 12AU7 on the Line Two. The input/output capabilities on the Line Two are perfect for my needs. But what about the sound comparison? Am I lucky enough to find someone out there that has experienced both?

A minor point, Sandspur, but the ASL preamp also has a power indicator LED. It is located just above the logo.

Also, something to consider is that I believe 6N16B's have leads which are probably soldered to the circuit board in the SA-31 and other audio components which utilize them, rather than being socketed. Although IIRC that tube is rated for a very long lifespan, so replacement would presumably be required rarely if ever.

Good luck, however you decide to proceed. Regards,

You might also consider selling the 214 and L40 and with the $500 in addition you are looking to spend, find a quite nice integrated...

Almarg, you caught me on the LED :). I started to look it up but decided to go ahead and post. Also, your technical knowledge and advice is much appreciated. I'm not familiar with IIRC but with a few key strokes I can learn a lot. I take it that the 12AU7 is something different?

J135, I have certainly considered what you suggested. The 214 is still a nice little amp. I tried to murder it one night during a partying frenzy. Fortunately, I found a good doctor who brought it back to life. We have had a good relationship since...just can't quite give up on her! As for the L40, it will be a great back-up and good for a bedroom.
