We talked about performance speakers and the importance of proper speaker placement in Part 1 of our Listening Room feature. We also covered the acoustic properties and critical dimensions of the room design. Now, let’s dive into what drives the sound!
The heart of your system driving sound to each channel is the amplifier. Unlike your Home Theater’s AV Receiver that houses an all-in-one pre-amp, amplifier and processor for surround sound, hi-end audio systems have dedicated amplifiers, often one per channel. A more sophisticated set-up will have 2-way or 3-way amps that support each speaker. A pre-amp serves as the input device. It will convert signals from all audio sources such as a tuner, turntable and streaming devices to the signal that the amp wants.
It’s essential that the amplifier be matched to the specifications of the speaker to provide optimal output. LaScala can guide you through your choices and design to your listening preferences. Our go-to is Classé, part of the B&W Group. Their line of components offers exquisite sound to complement any hi-end audio system. Check out this recent review of the Sigma 2200i integrated amplifier by Stereophile.
It is common knowledge that HDMI Cables are required to pass 4K and hi-end audio has similar requirements. Like video, quality cables are recommended for a solid, clean connection. That doesn’t necessarily mean the most expensive, just of good quality and appropriately sized for the given application. We can calculate the appropriate gauge cable that will deliver the necessary wattage to the speaker based on the distance. As for the connectors, gold are preferred over silver or other metallic. Locking connectors are a good choice for equipment that is seldom moved.
Having sufficient, clean power is paramount to the sound quality. Every AV system needs a name brand, purposely built, surge protector. Surge protection will remove artifacts from your power, filtering out spikes and dips. Insufficient power can make the amplifiers put out harmonics that will “color” the sound, creating unwanted distortion.
Once the system has been designed and the components selected, the next step is installation and commissioning. Measuring and testing the room’s characteristics, reverb, etc., we’ll “tune” the room to enable undistorted sound. By adjusting equalization (EQ), gain structure and speaker placement, we target a flat frequency response.

We often hear that a turntable’s needle against vinyl is the only way to listen to music. It can be argued that the harmonic distortion created introduces a mild alteration that is perceived by many as warmth. The pops and crackles the needle yields evoke a “vintage” sense that some find pleasing and quite authentic. However, according to Mark Slee of Facebook, “In terms of fidelity and accuracy of sonic reproduction, CDs outperform vinyl in significant ways. With that said, there are sonic artifacts and emotional attachments with vinyl that many find pleasing. This creates a preference for vinyl – which some would describe as better, but this is a subjective quality as measured by the ear of the beholder.” With turntable sales up 16%, there’s apparently some “old schoolers” out there that agree.
The higher the bit rate of the audio, the more accurate the sound. Analog is uncompressed and the format truest to form. Overly processed audio, on the other hand, can mask or cancel parts of the music, eliminating the ability to hear everything as it was mastered.
All things being equal, the more information a format can transmit, the better the sound produced. For the best listening experience, the sound transmitted should pass through quality cabling and components and be listened to in a space that is purposefully designed to capture every nuance.

Hear the Music. Really Hear it. “I’ve listened to that song a thousand times and I’m hearing things I’ve never heard before.” That’s the definition of your perfect Listening Room. While our world of listening has transformed dramatically over the last decade, all that matters is what you want to hear. The science and mathematics are real, as are the hi-end audio components. The rest is subjective.
Loudspeakers convert electrical impulses into sound. Depending on the dimensions of the room, as well as the listener’s preferences, a well-designed audio system will transmit the desired range of frequencies (note that it may not be the widest range). Some audiophiles swear by 2-channel, with speakers positioned a calculated distance apart and at an optimal distance from the listener, facing the listener for a 2 dimensional listening experience. The 2-channel system creates a virtual sound stage. When professionally set-up, the listener is able to close his/her eyes and actually pick out exactly where, on the “stage”, that musician was positioned. Unlike viewing a movie, there is no need for various sounds (voice, music, effects) to “follow” around the room, so rear speakers or a full surround sound system are not desired. In fact, some find it unnatural for instruments to be heard behind them. The perfect speaker system, in the perfect acoustically treated room, will reproduce the sound as authentically as possible. However, while science can measure all facets of sound, the listening experience is quite personal and our passion for particular brands is rather cult-like. We, of course, have our favorites too.
An industry icon with a prestigious reputation built over 5 decades, Bowers & Wilkins touts its 800 Diamond Series as “the industry standard for accurate sound.” We couldn’t agree more. The Diamond Dome tweeters of the iconic 802 D3 deliver natural treble while its Continuum cone and Aerofil cone provide amazing, subwoofer-free, midrange and bass, respectively. Frequently the subject of audiophile reviews, the B&W Diamond Series does not disappoint. The D3 was unveiled last summer in Boston. Here’s a review featured in Audioholics that details the author’s experience of both the D3 as well as B&W’s flagship speaker, the $60k per pair Nautilus. The line’s CM Series, with its minimalist exterior and “tweeter on top” technology, also offers incredible audio performance. It is designed with the highest quality components and a “less is more” philosophy that ensures “nothing gets between you and the sound the artist intended you to hear.”
Equally as important to the components is the environment. The ideal listening room will be free of ambient noise and other distractions. Acoustic treatments will absorb the hum of the HVAC and rattling water pipes. The space will be free of harsh lighting, filled only with soft, relaxing light and there will be no capacity for video. This combination of exceptional components producing nearly flawless sound and the distraction-free environment, will allow the listener to hear subtle artifacts in the music that were previously unnoticed.
The room’s furnishings and physical dimensions are essential to the experience. The proper room requires some soft surfaces – some will say that even a glass coffee table or leather couch is not suitable as they will reflect sound, opting instead for fabric seating. The height of the seat back is recommended to be below the listener’s ear level, allowing unobstructed hearing without reflection. The single seat should be positioned in what will be known as the “sweet spot” or “money seat,” as determined by the engineer’s calculations. The calculations for the room itself are also of great importance. To determine an acoustically accurate room for optimal listening, audio engineers employ the Bonello Graph, a method of calculating the ideal room ratio of dimension and volume, explained here by AcousticFields.com. In the audiophile world, this is also referred to as the acoustic amoeba.
