A Modern Hi-Fi Turntable Designed for Stability and Musicality
This manual turntable positions itself as a device oriented towards hi-fi listening, with a design focused on rigidity and rotational consistency. The MDF chassis surround and the die-cast aluminum platter form a coherent base to limit unwanted vibrations and promote clean, stable, and nuanced sound reproduction.
The choice of a lacquered Walnut plinth finish combined with a gray body provides a look that is both warm and contemporary, easy to integrate into a living room, dedicated listening space, or a refined vinyl setup.
Who Is It For and What Are Its Uses?
This model is aimed at vinyl enthusiasts who want to step up to more precise listening without entering overly complex adjustments. It is well suited for a beginner to advanced hi-fi audience looking for a serious turntable to rediscover their collection, enjoy a more readable soundstage, and gain detail on vocals, cymbals, and textures.
Its manual operation will appeal to those who appreciate the vinyl ritual and direct control over operations (start, stop, speed change). It is ideal for domestic listening (living room, office, dedicated room) and listening studios to check pressings, archive, or compare masters, provided it is paired with a suitable phono preamp.
Features and Innovations
The turntable is based on a direct drive system and simple speed management: 33 1/3 RPM and 45 RPM, with manual switching via a front panel switch. The start and stop of rotation are also controlled by a front panel switch for immediate handling and clear ergonomics.
The TP 150 tonearm is equipped with an SME connection ring and a removable headshell, a real advantage for maintenance, system upgrades, or preparing a second headshell to alternate between different cartridges. The magnetic anti-skating contributes to better groove tracking, with a more balanced channel output and better stylus wear control when properly adjusted.
The supplied cartridge is an Ortofon 2M Blue with a 1/2" mount, featuring a moving magnet (MM). Its nude elliptical diamond aims for a clear gain in definition and finesse compared to simpler profiles, while maintaining versatile musicality. With an output level of 5.5 mV, it easily pairs with most MM phono inputs.
