Parasound and Marantz: Why Noble A-V Chooses These Amplifiers for Indianapolis AV Systems

Amplification is the most frequently underestimated component in an AV system. Clients often have strong opinions about speakers and displays and leave amplifier selection to the integrator. That deference is warranted — amplifier selection is technical and the options are numerous — but the choice matters more than most people understand. At Noble Audio & Video, two brands appear in our specifications more than any others: Parasound for high-performance two-channel and multichannel amplification, and Marantz for AV receivers and pre-amplifier/processor combinations. Here is why.

Parasound: John Curl's Engineering, Real-World Value

Parasound is a San Francisco-based company that has been building power amplifiers since 1981. What distinguishes Parasound is the involvement of designer John Curl — one of the most respected amplifier engineers in the industry, whose designs appear in equipment costing many multiples of what Parasound charges.

The Parasound HALO series — specifically the A21+, A23+, and JC5 stereo amplifiers, and the A51 five-channel amplifier — represents the best price-to-performance ratio available in high-end amplification. These amplifiers produce real, sustained power into difficult loads, run cool enough to be installed in equipment racks, and sound accurate without the coloration that characterizes some competing designs.

In practical Indianapolis installations, Parasound amplifiers appear in two contexts: driving premium loudspeakers in two-channel listening rooms (particularly when paired with Totem Acoustics speakers), and as external power amplifiers supplementing AV processors in dedicated home theaters. When a client has invested in reference-level speakers and wants the amplification to not be the limiting factor, Parasound is our recommendation.

Marantz: The AV Receiver Standard

Marantz has produced audio electronics in some form since 1953. The company's modern AV receivers — the Cinema 60 UHD, Cinema 70s, and Cinema 40 — represent the standard against which other AV receivers are measured in the $700 to $2,500 price range. Their pre-amplifier/processor products, including the AV10 and AV8805A, are what Noble A-V specifies for higher-end theater systems where the receiver's built-in amplification is separated from the processing function.

Why Marantz over competitors? Several specific reasons:

Audyssey MultEQ XT32 room correction: Marantz includes Audyssey's most advanced room correction algorithm in mid-range and above models. In Indianapolis area homes where basements and bonus rooms often have acoustic challenges — parallel walls, low ceilings, bare concrete — automatic room correction makes a measurable and audible difference. Audyssey MultEQ XT32 is more sophisticated than the equivalent systems in most competing brands at similar price points.

Build quality: Marantz power supplies and component quality are consistent. We have Marantz receivers in Indianapolis installations from fifteen years ago still operating without issue. That reliability track record matters when you are specifying equipment that will be integrated into a system and expected to operate for a decade.

Integration support: Marantz receivers have excellent Control4 and IP control integration. Two-way communication lets Control4 know the exact volume level, current input, and power state of the Marantz, enabling the kind of accurate scene control that distinguishes a professionally integrated system from a system with a universal remote.

Receivers vs. Separates: How We Choose

For media rooms and systems with a budget of $3,000 to $8,000 for electronics, a Marantz AV receiver provides excellent value — quality amplification, comprehensive processing, Audyssey room correction, and extensive streaming integration in a single chassis. For dedicated theaters with $10,000+ electronics budgets, separating the pre-amplifier/processor from the power amplification (a Marantz AV10 processor driving Parasound A51 or A23+ amplifiers, for example) produces a meaningful performance improvement and greater flexibility for future upgrades.

The Indianapolis Market Context

Hamilton County homes — particularly in Carmel, Zionsville, and western Noblesville — increasingly have dedicated theater rooms or premium media rooms as a standard feature. The clients in these homes are sophisticated consumers who have done research and understand the difference between a Costco soundbar system and a professionally designed AV system. They do not want components that will embarrass them in a comparison. Parasound and Marantz components do not embarrass us in any comparison we have seen.
