Nordost QBase QB4 Unit and QV2 Line Harmonizer Series 1

I am selling them together for one price since the QV2 is designed to be used with the QB4 (see the attached pic). Retail for both is $1200.00. The units work flawlessly and the reason for the 8/10 rating is there are a few scratches around one of the outlets in the QB4 and on base caused by during normal use. The scratches are shown in the pictures and the unit has been priced accordingly. No factory box but they packed with care.

Please check my FEEDBACK.

QBASE QB4 AC DISTRIBUTION

The essence of the QBASE-Mark II concept is a straight-line AC distribution path, combined with star-earthed topology for connection to a clean ground. By eliminating any form of in-line filtering or active circuitry we maintain the lowest possible AC supply impedance, while a tiny lift in the earth impedance of all but one of the output sockets routes the signal grounds directly to the center of the star and the clean earth terminal. Clearly identified on the casework, this Primary Earth socket is at the center of your system’s performance, literally and metaphorically. It defines both the order in which you connect your components and also, their listening priority in your musical enjoyment, allowing you to further optimize the performance of your primary sources.

The sockets themselves are mounted on a customized frame plate and solidly constructed aluminum extrusion with machined end-caps that deliver a reassuring sense of substance. But the casework has far greater significance than that, the metal pieces and internal PCB (deliberately preferred to hard-wiring) constituting a single, mechanically tuned construction, designed specifically to enhance performance. Compare the musical performance of the QBASE to the competition and you’ll hear just how effective this is.

A QBASE unit is the perfect starting point in the construction of a high-quality, modular AC supply for your system. Its compact dimensions mean that, in addition to combining it with the QV2 discussed below, it can be easily combined with additional Qv2 AC Line Harmonizers; one or more Qx power purifiers and with Qk1 AC Enhancers while its slim profile makes it ideal for tucking away behind a rack or mounting on the wall.

QV2 AC LINE HARMONIZER

The Qv2 is an AC Line Harmonizer that is designed to enhance the musical performance and picture quality of any audio or video system, delivering readily demonstrable benefits at an incredibly affordable price. It can be used with the Qbase, as a “stand alone” product or to complement a full QRT system including QBASE, Qx4, Qx2 and Qk1 units. The Qv2 works directly on the AC line, introducing a carefully calculated range of pulsed frequencies, clocked from the original 50 or 60Hz waveform. The result is a drop in noise floor, with a commensurate increase in image depth, dimensionality and presence, significantly increasing the realism of both musical and visual performance.

Like other QRT products, the benefits are cumulative and Qv2s are even more impressive when used en masse. The compact, “plug-top” construction of the Qv2’s mechanically tuned housing allows it to be inserted into any free socket on your system’s AC line – although adding directly to a QBASE-Mark II maximizes the benefits.

Qv2 units are available in either US (NEMA) or EU (Schuko) configurations, and compatible with 50/60Hz 100 – 240V supplies. However, standard adaptors can be used to employ the Qv2 in other markets. The Qv2 is housed in a mechanically tuned carbon fiber and has high quality gold plated connection pins. It is built entirely in the USA and carries a two-year warranty.

• Works directly on the AC line, actively introducing a precise range of pulsed frequencies

• Increases the depth and realism of the musical performance.

• Lower perceived background noise.

• Deeper, more dimensional and more vibrant picture on AV systems.
