Letters to the editor: Suitcase Coffee Co., Onix, Klarita Muso

  • The pursuit of better coffee is none too dissimilar to the pursuit of better sound: we marry machines to trial and error (that sums to experience) in order to improve the quality of an outcome. And so we start this edition of ‘Letters to the editor’ with an email response to a recent pair of videos in which I led with the black stuff before diving into starter system possibilities.

    Morning John,

    I will be in touch shortly about some of our speakers but firstly my lovely sister owns a coffee company: The Suitcase Coffee Company.

    Wondered if you wanted some to try? If yes give me an address and I’ll get some sent over.

    Hello John,

    I look at your YouTube videos on various aspects of Hi-Fi. I have used all sorts of equipment over the years, but now being retired my income is more modest.

    Can I recommend you have a look at a computer program called Muso. You will find it by putting in a search engine ‘Klarita Muso‘.

    This program is a front-end alternative (for me anyway) for the Logitech Media Server. It can be used on other systems as well and I know the author of the software Jeremy Bradshaw would welcome your interest in the system, bearing in mind the number of views you get for your videos.

    Can I point out, I am in no way connected financially to this software or the author. I am an enthusiastic user and I believe a wider audience could make use of its brilliant abilities.

    I hope you find the time.

    Hi John

    I don’t know if you are interested in iconic 80s hi-fi but 35 x ONIX OA21s are being manufactured to celebrate 35 years since the amp was first manufactured.

    You will have to be quick though as there are not many remaining. Search ‘onixdna‘. SOAP power supply available later I believe.

    Lots on Pinkfish.

    Hi John

    I stumbled upon your site this past year. Thank you for what you do. I have been thinking about an upgrade, find the diminishing cost of returns challenging. Your exposé on active speakers has been excellent, and likely the way I’ll go. The LS50w is very accessible, but in Western Canada getting to audition the Navis is challenging. My impression is dealers who offer both don’t want to roll out the Navis.

    Recently you noted you had some playlists associated with some reviews. I checked out the Auralic playlist on Spotify. It was nice to understand your reference to Toms Waits’ voice as you mention in a number of reviews. And, huge bonus, hearing some new music (well old music, but ‘low’ was something I had no idea was recorded). Looking forward to more.

    Hi John,

    I always check out your site, appreciate your review coverage and admire the high quality of your YouTube videos (including Jana’s leading-edge, professional-quality editing).

    I’ve read your various reviews and mentions of Allo products with interest. I see that Allo is ready to send out review samples of their new Revolution USB DAC [I don’t see this on their website – Ed]. I expect one is destined for you and I’m hoping that you will personally review it.

    All the best,
