McCormack ALD Dlx w phono

Hi Tbromgard -

Both the balanced (XLR) and unbalanced (RCA) outputs come from the same output-stage amplifiers, so the quality is the same, so to speak. The unbalanced output simply uses 1 amplifier channel - not both. The real question becomes whether or not your amplifier has balanced inputs (the stock DNA-0.5 does not). If it does, I would suggest using the balanced connections. If not, just use the RCA unbalanced output connections. By the way, you may use both sets of outputs at the same time if need be. You could run a powered subwoofer or a remote amplifier in addition to your main amp, for instance.

Enjoy!

This is my first post on Audiogon, and its was cool to see the first response from the manufacturer himself-thanks Steve. Your electronics are first rate, and when I have the funds, I intend to have this unit upgraded by McCormack. Please continue to offer improvements and uprades to your older models. Thanks.

Thanks for your kind words, Tbromgard. I hope you enjoy your ALD-1. One small correction - McCormack Audio does not offer upgrades. They are available from SMc Audio - my own business. Check my website at www.SMcAudio.com for the details.

Steve-
What kinds of speakers did you use when designing the ALD-1 with phono? What kind of turntable did you use?
Thanks -Todd.

Hi Todd -

The ALD-1 (Active Line Drive) was designed back in the early '90s. At the time I was using a variety of speakers like the Thiel 3.6, the Vandersteen Model 4, and the Stax ELS-F83X. For turntables I would typically use an Oracle Delphi with a Triplanar tonearm.

Hi Steve-
I purchased a DNA .5 to go with my newly aquired ALD w/phono and external power supply. I understand that they should not be stacked, but placed a few feet apart from each other. Is this correct? Thanks, Todd.

You are correct, Todd - stacking is not recommended. It is a good idea to keep at least a foot or so of distance between the ALD-1 and another power transformer (like an amplifier). This will minimize the possibility of radiated noise pickup in the phono section. Beyond that, it is always a good idea to keep equipment on separate shelves, preferably with some sort of damping and isolation.
