Main Stream - Master Class Dynamic Parallel AC Line Conditioner

Main Stream is designed to improve the performance of your high-end audio or video system by reducing the amount of AC Mains-based interference travelling on the wires within your home. This interference is created not only by other components in the system but also appliances and other electrical equipment elsewhere in the house. Sometimes even emanating from outside your home!

Of course, this interference is mostly in the RF range, but things like refrigerators, air conditioners and heaters, washers and dryers—anything with a big motor and put a pulse of energy on your home AC line, and it will be "felt" by other equipment within the home. The energy imposed on the line is absorbed or filtered in different ways, depending on the frequency band involved. Part of Mainstream's effectiveness is due to the multiple frequency bands it effects while utilizing a simple topology comprising a minimum number of parts.

Mainstream uses a combination of reactive elements to create tuned filters designed to specifically reduce the levels of noise specifically known to interfere with your audio enjoyment. Our topology excludes the use of any type of resonant transformer as a wave shaping device and rather only removes unwanted frequencies.

SnubWay - Noise Defender

SnubWay is an advanced parallel mains noise filter utilizing 4 discrete LRC filters tuned to absorb high-frequency noise from switch-mode power supplies (SMPS) and other sources in the 10 kHz to 2 MHz frequency range. Today’s homes have power lines that are constantly polluted with dirty pulse switching noises from SMPS that are so ubiquitous in modern homes. From our cell phone chargers to the power supplies for LED lamps and even our laptop computer supplies. They all utilize high-speed switching in the 100 kHz to 1 MHz range, and they often leak noise back into the house AC mains.

The SnubWay mains noise filter has multiple LRC-tuned resonant snubbers to absorb this unwanted noisy energy from SMPS’s over a broad frequency range. The LRC filters utilize nano-graphite pulse absorbers to provide a broader frequency absorption band and high-quality polyethylene film capacitors combined with precision wound copper coil inductors. The discrete filters are computer tuned and designed for optimal performance. The filters are arranged in parallel to absorb a broad range of sinusoidal and transient pulse noise sources. The LRC filters are arranged on separate PCB assemblies stacked and connected in parallel using solid 14-gauge copper wire buses. All of this is encased in a state-of-the art aluminum housing and utilizes custom-made premium Viborg plug housing with solid copper prongs and hardware.

物有所值!

我的系统有两条HIFI专线:
A线路:Aurender N150,Innuos Phoenix USB Reclocker,精音DAC-D1000 MK2(R2R)。
B线路:小不点LD-Y3全平衡300B胆机耳放。
从国外论坛中了解到Vera-Fi Audio的SnubWay和Main Stream这两款降噪新品后,我联系了Mark。在30天免费退货的条件下,我尝试了这两款产品。此前我用过日本Furutech NCF Clear Line电源净化器和美国Shunyata Research Venom Defender电源优化调谐器,但效果不够明显,也不够理想。按照Mark的指示,并联设备需要通电400小时才能达到最佳状态,目前我的通电时间已接近400小时。
由于SnubWay和Main Stream体积较大(三角形设计),如果和电源线一起插入美标插座,空间不够,所以我自制了几条公母转接线来搭配。我将SnubWay(2个)和Main Stream(1个)放置在以下位置:
SnubWay #1:插入A线路的Sierra 20A镀金背插座,通过Hubbell橡胶插头转接线与CARDAS Clear Power电源线并联,供电给Aurender N150数播。
SnubWay #2:插入B线路的A&H-H 6262-2 DELUXE电木插座,通过电木插头转接线接入,与A.R.T. AC-8 G1电源线并联,供电给小不点LD-Y3耳放。
Main Stream:插入B线路的Hubbell 9595 + HUBBELL BK-12433总墙插。

听感上的变化:
加入这三个并联降噪设备后,我试听了熟悉的曲目,包括交响乐(如马勒《第二交响曲》)、人声(如蔡琴《渡口》)和爵士(如Dave Brubeck《Take Five》)。整体听感提升明显,背景黑度更深,细节更清晰。以下是具体变化:
背景黑度更深,细节更清晰
在A线路加入SnubWay #1后,数播端的背景噪声明显减少。播放《渡口》时,蔡琴的呼吸声和低频鼓点之间的空隙感更强,细节浮现得更为自然。以前偶尔能察觉到的微弱“沙沙”声几乎完全消失,背景变得像“墨汁般黑”,让人更专注于音乐本身。
声场扩展,3D感增强
Main Stream在B线路的加入对声场影响显著。听《第二交响曲》时,乐团的纵深感和定位更立体,弦乐组与铜管组层次分明,仿佛能感受到乐手之间的距离。相比之前,声场宽度和深度都扩展了不少,3D包围感让人有种“置身现场”的沉浸感。
低频下潜更深,纹理更丰富
SnubWay #2和Main Stream在B线路的协同作用,让耳放的低频表现更上一层楼。《Take Five》的鼓点下潜更深,力度感更强,同时低频的纹理和扩散感也更自然,不再有那种“糊在一起”的感觉。尤其是Main Stream加入后,过滤了家电电机噪声,低频的氛围感更浓厚,整体听起来更松弛有力。
人声情感更细腻,动态更宽松
人声方面,《渡口》中蔡琴的声音轮廓更清晰,情感的起伏和喉韵细节被放大,显得更有温度和感染力。动态范围也有提升,弱音到强音的过渡更顺畅自然,没有之前那种轻微的“压迫感”,乐感变得更抓耳。
整体氛围感和乐感提升
三者搭配后,系统整体的氛围感明显增强,音乐不再只是“精准还原”,而是多了一份活生生的生命力。无论是大编制的恢弘,还是小编制的情绪流淌,都让人更容易沉浸其中,长时间聆听也不觉得疲惫。

Vera-Fi Audio的SnubWay和Main Stream作为并联降噪设备,在我的系统中发挥了“锦上添花”的作用。SnubWay的高频噪声过滤能力让前端和放大环节的背景更干净,而Main Stream在低频和动态上带来了惊喜,两者协同工作将系统的潜力进一步挖掘出来。这三件“手雷”性价比很高,绝对是“调音利器”。
在使用这三个设备的过程中,Mark非常热情,有问必答,让我感到很亲切。我愿意尝试更多Vera-Fi Audio的产品,Mark很专业,同时也要感谢Mark的同事Peter。有时候对于Hi-Fi玩家来说,有些东西看似玄学,但其实背后有更多科学技术的支撑。Vera-Fi Audio的产品物有所值!

The very best plug in AC Filters in the world

This is my second purchase of these extraordinary performing AC Filters. No BS marketing claims these are the real deal and Mark offers absolutely top service all around. The improvements in my systems are across the board cleaner, clearer, revealing details of the music I have never heard or “felt” before, These are a no brainier for any system and work alongside both my two different high end conditioners which I no longer require as the Snubway + Mainstream combined are better on their own! Congratulations Mark + team you deserve all the credit for providing world leading products without pulling our pants down.

Blacker background, more bass, tighter bass, bigger soundstage and to top it all off, my TV picture is clearer. To tell the truth I didn't think this addition would have as much effect on the sound as it has, but I was wrong. Everything I have purchased from Vera-FI has made an improvement in my system.
