Air Tight Opus-1

Stereo MC Phono Cartridge

Air Tight Opus-1 Ermitage cartridge, released in honour of AirTight’s 30th anniversary is in the very top echelon of MC phono cartridges in the world and offers a performance that has to be heard to be believed. It is the result of many years of development and collaboration between the most renowned Japanese cartridge designers.

It incorporates a unique (exclusive to the Opus-1) ultimate performance SH-uX core sealed in an ultra-hard duralumin housing which is then fortified by nickel plating. It aims at delivering the optimum combination ratio of internal impedance and output voltage. This technology gives the Opus-1 the ability to reproduce slight changes in signal intensity as a continuum and differentiate between subtle shades with ease.

Drop it into a groove and the Opus-1 opens a world of palpable three-dimensional imaging, a wide and deep soundstage and a sense of realism reminiscent of a live event. Such is its sublime sonic picture that the listener is drawn into the music with a deep emotional engagement and sense of believably. For audiophiles who are searching for the ultimate performing cartridge to add to their analogue system, the AirTight Opus-1 must be on their short list. Rare and uncompromisingly brilliant.

The Absolute Sound, Jonothan Valin, 2016

How does it sound? In a word, solid. The Opus-1 may be the most three-dimensional-sounding cartridge I’ve heard in my home. Where (on my fabulously high-resolution system) a low-impedance/low-output cartridge like the Ortofon A90 will reproduce Dean Martin’s voice (on Analogue Productions’ superb reissue of Dreamin’ with Dean) with so much fine detail you can tell how much spit (or bourbon) Dean-o has in his mouth on any given note, the Opus-1 slightly dials down the analytics but turns up the volume, converting Dean from a highly detailed albeit paper-flat acoustic image to a fair semblance of an actual human being standing in front of you. It’s like the difference between watching a film and watching a play…. The Air Tight Opus-1 gets my highest recommendation, and joins the Goldfinger Statement and Ortofon Anna as one of my references.

Positive Feedback, Marshall Nack, 2017

The Opus confronted me with a different soundscape each time I changed LPs. Ephemeral nuances that may have been dimly present, merely hinted at, were now clear as day. It didn’t matter whether the signal was soft or loud; the Opus never compromised the quality of sound. Musicality was always retained….. Barring the cost, the Opus is the best thing for analog since sliced bread.

My four approve
Color: 3PC-Bacon-Brown, Pattern Name: Tough Dog Toys
My dogs, which I have 4, 2 labradors, one Jack Russell and one medium smallish mixed breed dog, all really love the bones. Three of them seem to be vigorous chewers the mixed breed girl being the toughest one on bones. These bones are holding up really well and the dogs really seem to like them. The dogs have not been able to get any big chunks off of the bones so I feel safe letting them have them even when I’m not watching. I would recommend these to Pet owners.

I have a medium sized dog and these were to big for him. A bigger dog would love them. Great for chewers.

Great enrichment
Size: 2.8in for Small & Medium Dogs
These are great for our 3 dogs, they’re durable and strong. The pup ford training treats fit great into these and it takes our dogs a good bit to get all the treats out. Easy to clean and a great enrichment toy, will buy again!

My dog looks forward to this every day
Size: 2.8in for Small & Medium Dogs
My dog used to have separation anxiety every time I left the house. I tried to find things to distract her when I left, but nothing kept her attention long enough for me to get out of the house. I stuff treats in this ball and she keeps focused and gets all of the treats out. Perfect solution to keep her occupied as I leave for work. Very easy to put treats in and I’ve had it for about 6 months now, which is great because my dog chews toys to pieces within days! High quality ball. I love it so much (well, my dog loves it so much), I bought one to give my neighbor’s dog.
