Newbie Tubie just wants insight and direction....


Hi All and Happy Holidays!
I recently acquired a used Antique Sound Lab 1001dt, it's not the newest version with remote but it does have the built-in bias meter (thank God for this!).

I've recently come over from the SS camp owning a B&K AVR 307. What I'm noticing, and this is only 2 ch vs. 2 ch for the B&K vs. the ASL, is that for HT/movies, I don't get a good center image. I've checked all the settings on the 999es to make sure that it's in downmix 2ch. mode/analog only out so basically I'm only swapping out the amplifiers.

I get a great center image with the B&K but with the ASL the sound seems to be coming from just left and right...not "transparent" if that's the right term. Voices just don't jump out from the middle of the screen as it does with the B&K.

Now, as far as music goes, it's a totally different story, it's HUGE and lucious, velvety and "easy" but there are still some times when I feel that the music doesn't have the proper staging or imaging conjuring up one large ensemble out in front of me or to the center.

Is this just an "experience" of moving from SS to Tube gear or do you think there may be other issues to deal with.

For all purposes I've included all equipment relative to this question below.

Thank you in advance for any insight or advice, tips or tricks...again, Happy Holidays!

Your new tube rig advocate!

Current equipment:
Marantz 63se
Sony 999ES for SACD and HT duties
ASL 1001dt integrated (JJ Tesla kt88's stock 12au7's)
Paradigm Reference Studio 20's V.2's
Silent Audio Apollo C's (the silver ones, can't remember whether these are the C's or the A's)
Signal Cable Bi-wire
Signal Power Cord

I have other equipment but I'll focus on these for now since my question really pertains to 2 channel.

Get a demo and set-up disc and make sure your phasing of the two channels is correct. Either your speakers or (god forbid) your amp outputs are out of phase with one another, buit I 've seen this happen!
the phase on my speaker cables and to see if the image improves?

I guess I can answer that question myself by just trying it.

Where can I find such a disc for set-up? Do any of the Avia or DVE discs have this option? I was thinking of picking one of these up anyway for my rp calibration.

Thanks again for the insight and suggestions!
No disc required. Tube components often do not invert phase. One more unecessary component in teh signal path. Switch polarity at either speaker or amplifier and you should be set.

Your observations prove that you were in deed listening.

Happy holidays!
