Despite not offering a vacuum system, it has been frequently compared favourably in reviews to other turntables at higher pricing levels which feature vacuum. For many owners, the vacuum system may be deemed to be unnecessary. However, for those customers who demand a vacuum system for the benefits that it gives and desire to have that ‘ultimate’ specification of a Dohmann turntable, the Helix Two Mk3 Vacuum is a revelation. The vacuum system creates suction and turns itself off just as the stylus touches the grooves. There’s no pump action during replay at all and even if the system experienced a loss of suction which required the pump to activate, it is designed in a way that its operation is silent and decoupled from any aspect of the system that may affect the sonic performance. Furthermore, the ‘virtual o-ring’ technology results in absolutely no influence of platter inertia whatsoever. This level of performance is simply unprecedented.\u003c\/p\u003e\n\u003cp\u003ePlease read the information on the Helix Two Mk3 to better appreciate the foundations for this statement turntable by internationally acclaimed analogue designer Mark Dohmann and his team.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does a vacuum hold-down system do?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA vacuum turntable uses a gentle suction beneath the record to draw the vinyl firmly and uniformly onto the platter surface. For this to work, the platter must have a special design: an air channel or pathway and a sealing mat or lip around the edge that allows the vacuum to create a seal under the record. Once the vacuum is engaged, the vinyl becomes effectively part of the platter — fully “coupled” and flat, eliminating air gaps and ensuring full-surface contact. This pressure is evenly spread across the whole disc, not just at the label\/spindle area (as with a clamp) or edge (as with some stabiliser rings). Aside from presenting a flat vinyl record, the vinyl and the platter present as one ‘effective mass’, which has sonic benefits.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat are the sonic benefits of a well-designed vacuum hold-down system?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eEliminates warps and air gaps\u003c\/strong\u003e\u003cbr\u003eA vacuum hold-down system forcibly flattens the record against the platter, whether the vinyl is slightly warped, has uneven pressing or simply isn’t perfectly flat. This ensures the stylus rides the grooves with consistent geometry. This can help avoid groove mis-tracking, distortion, or pitch instability that might otherwise result from warps or uneven contact. Because the entire surface is in intimate contact, you avoid “air pockets” under the record that might introduce resonance or micro-flutter.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBetter stylus tracking and groove contact\u003c\/strong\u003e\u003cbr\u003eWith the record held perfectly flat and flush, the stylus can maintain consistent contact with the groove walls and floor, which improves tracking accuracy. This helps especially with delicate groove passages, subtle dynamics, and complex recording mixes, where even slight variations in contact can smear or blur detail. Also, because vacuum hold-down distributes force over the entire disc, it avoids some of the potential downsides of clamps (which only press at center) or weights (which increase inertia but may not flatten warped records completely).\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eReduces resonance, vibration \u0026amp; feedback loops\u003c\/strong\u003e\u003cbr\u003eAnalog playback is highly sensitive: as the stylus tracks the groove, it generates tiny vibrations. Those vibrations can travel from the vinyl to the platter, bearing, and even into the tonearm or plinth — potentially feeding back into the stylus and muddying detail. By rigidly coupling the vinyl to the platter, the vacuum system reduces the chances for micro-movements and resonance, minimising energy interplay between the stylus and platter. This means fewer distortions, less “smearing,” and a more stable, accurate reproduction of the groove’s fine details.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMore consistent speed \u0026amp; stability (less wow\/flutter noise)\u003c\/strong\u003e\u003cbr\u003eOnce the record is tightly coupled to the platter, there’s less likelihood of slippage or micro-variations in rotation, both of which can cause wow and flutter (subtle pitch fluctuations) or timing instability. A vacuum system results in a minimal increase in rotational inertia compared to heavy weights, meaning less strain on the motor and platter bearing, yet you gain improved rotational stability.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIncrease in sonic clarity, detail and accuracy\u003c\/strong\u003e\u003cbr\u003eThe overall improvement of superior stylus contact, reduced micro-vibrations and the elimination of warps\/air gaps is less resonance and fewer mechanical anomalies. This allows the stylus to convert the groove geometry into an electrical signal more accurately. Discerning listeners report fewer distortions or colorations, which often improves midrange purity and clarity of vocals and instruments. Tighter bass, greater low frequency clarity, improved transient impact (drums, percussion), more image stability and better overall fidelity.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy have we delayed offering our customers this feature?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eMark Dohmann has been building turntables since 1982 and has a lot of experience designing and building vacuum hold-down systems. When Dohmann Audio started the Helix project in 2013, Mark designed the Helix One and Two from the beginning with the vision to incorporate a vacuum system in the future. The architecture of the Helix platform has always had accommodations for a vacuum system and we have been quietly working away on a vacuum hold-down system with the intention of introducing it when we felt that it would represent value to our customers.\u003c\/p\u003e\n\u003cp\u003eAs our research \u0026amp; development progressed in the ensuing years, we were able to bring the operating noise floor of our turntables to unprecedented low levels. Due to advances in materials science, engineering \u0026amp; manufacturing technologies and test equipment capability, the Mk3 generation of turntables in particular are operating with noise floors that would have been considered impossible a few years ago.\u003c\/p\u003e\n\u003cp\u003eThis rapid technological development posed a problem for incorporating a vacuum hold-down system. Traditional vacuum systems are relatively unsophisticated, contributing noise and various sonic artefacts to the playback performance. They can also be unreliable, require onerous maintenance and in high resolving hi-fi systems, can be heard operating during music playback. The lower we dropped our operating noise floor, the harder it became to incorporate a vacuum system that did not interfere with the playback performance and did not suffer from the traditional vacuum system issues.\u003c\/p\u003e\n\u003cp\u003eWe realised that to satisfy those customers who desired a vacuum hold-down system in our turntables, we had to go back to the drawing board and design something completely different to what has been used in the past. Mark consulted with the industrial manufacturing industry and researched the most advanced vacuum systems used in this sector. He found a new way of applying these technologies to the ecosystem of a turntable. The result is an advanced Rotary Feedthrough Technology using ‘shaped oil’ virtual o’ring seal technology to protect the rotating shaft and platter from air leaks. It has taken us a few years to create a version of this technology that can be used in audio reproduction but the wait has been worth it.\u003c\/p\u003e\n\u003cp\u003eThe Dohmann vacuum hold-down technology is revolutionary in that it has never appeared in turntable applications before and it is so far advanced from existing vacuum designs that we can finally introduce it as an option to our customers. Finally, a vacuum system which is completely operationally sonically INVISIBLE and highly reliable, resulting in a positive ownership experience with elevated performance benefits.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eUpgradability\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe Helix Two platform is fully upgradable. Mk1 and Mk2 generation turntables are upgradable to Mk3 and the Mk3 is upgradable to vacuum specification. This protects our customer’s investment and avoids significant depreciation often experienced when a new model is released.

First, pretty much the granddaddy of nasty rockers; the mono version of You Really Got Me from the excellent compilation The Kinks’ The Journey – Part 1. Nascent, primal fuzz guitar, snarling vocals. Then some soft etherial harmonies from the Nineties courtesy of underrated songstresses Wilson Phillips. The results are exactly the same: thanks to the Döhmann Helix Two Mk3, it is an exquisite experience, like hearing them at their very, very best. \u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/nirvanasound.com\/wp-content\/uploads\/reviews\/HFC-Helix-Two-Mk3-Dohmann-Review.pdf\"\u003eRead Review\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003eAnalog Planet, Mike Mettler, 2023\u003c\/p\u003e\n\u003cp\u003eEven though Helix series’ tables have traditionally landed in the higher end of the SRP spectrum in terms of what we lean toward reviewing these days, they are indeed worthy of our aspirational attention as being both performance marvels and, frankly, works of art.\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/www.analogplanet.com\/content\/d%C3%B6hmann-helix-two-mk3-turntable\"\u003eRead Review\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003ePositive Feedback Part 2, David W.
