Cable connect to Harbeth 30 2.0

No problem doing that! I have done that on my single post Harbeths with my Bi-Wire cable with no ill effects!

Thanks! Now I have time to decide which way to go.

I use this product to double up my cables. It makes it a lot easier. Good luck with your new Harbeths!

Got my 30.2 XDs today. I was able to get the spades tightened down well, and they sound fantastic.

Ctwith3 --- can you describe the sound of your new 30.2 XDs?  How are they placed in your room?  What stands are you using?  I just order a pair --my first Harbeths.

yes you can

I'm-my using the TonTräger stands. The sound is amazing (especially with my brand new phono stage). They present a very wide sound stage, not the best bass in the world by themselves, but very good, and clear highs that hang in the air perfectly complemented by a full midrange that beautifully fills In the sound field between he tweeter and the bass. I have a REL T/7i subwoofer that provides the low to house-shaking bass perfectly. With any bookshelf speaker system a single subwoofer handles all that real low end. I can tell you that I listen without the subwoofer off half the time. If your system is synergistic you'll have plenty of bass- I gained that Synergism and better bass with my new phono stage- my amp was a little bright before and I had planned on replacing it within the next year, but the phono stage tamed the brightness and made my somewhat sloppy bottom end more punchy, tight, and just better all around.
Givd your speakers time to break-in at low to medium volume st best during break-in, and in a few weeks they will sound better. Truly transparent, holographic (in the right way), and gorgeous high vocals and transients. I was a little unsure about them because I hadn't heard Harbeths in a year, plus these are a new edition, and am extremely happy. My wife loves them- not kidding, we refer to them as her speakers. You should be very happy. Congrats! Let me know about your experience.

... my speakers are 7' apart and 1.5' in front of my system.
Also, I meant to share with you that I found out that Cardas will re-terminate their speaker cables for a reasonable price and am having them done so I don't have to continue stacking my high and low bi-wire leads onto the posts.
