  McCormack DNA-1 compared to Parasound HCA-1500A
I know this may seem like a ridiculous comparison to some of you, but I want to understand the real differences between mid-fi and hi-fi amps (other than cost). I know the DNA-1 can drive 2 ohm loads, but aside from that, what audible differences exist? I know that specs aren't the be-all-end-all, but they're all I have to go by. I own the Parasound and I'm happy with the sound, but I plan to biamp, which begs the question whether I should upgrade. I haven't heard the DNA-1, but I've read stellar reviews about McCormack amps and it's piqued my interest. Ideally, I want my system to disappear and create a natural soundstage with a tight bottom end. I'm currently driving a pair of Dahlquist DQ-20i's. They may be the weakest link in my system, but I like their sound and I can't afford to upgrade right now. A biamp arrangement will benefit any future speaker I bring in. Associated equipment: Anthem Pre-2L, Rega Planet 2000, Rega P3, Denon DL-103, Musical Fidelity X-LPS.

Insights and suggestions are warmly welcomed.

Many thanks in advance. -Mark

I assure you the McCormack is a much better sounding amplifier. Years ago I replaced a Parasound HCA 2200 II with a standard DNA-1 and this was quite an improvement. The McCormack is more refined and balanced sounding with a slightly warm midrange that is not unlike tubes. My advice is to make the switch.

I picked up the McCormack Micro drive amp a bit ago. It's the model right below the DNA-1. It's an absolutely amazing amp. I can't believe how huge the soundstage is and how powerful it sounds. 100 percent dissapears (and this one is only 50 watts!). It seems very underpriced for when it came out! I serverely doubt the parasound will even be close to the same league as the DNA-1.

All McCormack amps are head & shoulders above Parasound especially the ones with revisions.

I thought I should follow up with this post. I ended up buying a pair of NuForce 8.02b's. I've had them for about month now and I'm pleased with the sound. I definitely notice a new clarity. I'm biamping with the NuForce running the HF and the Parasound to the LF. When I get antsy in the future, I'll look for a used McCormack. If there had been one available at the time, I would have preferred to go that route, but I'm impressed with the NuForce. It's amazing how small they are and how cool they run. It's easy to the appeal for home theater. The 8 series are selling for dirt cheap right now.

Anyway, thanks to everyone for the suggestions and advice. I appreciate it.
