    What is the benefit of very expensive DAC´s?

    If the design of the DAC in question is based mostly on its filtering and computational prowess, then there may not be that much sonic difference between the $3500 DAC and the $43,000 one, but if it is designed as a unified whole with great emphasis on the elegance of its circuitry, the quality...

    Sigma Delta VS. R2R - SW1X

    Slawa Roschkow of SW1X has chosen the R2R architecture over Sigma Delta. Here are his words on the subject: “It is true, the specs of Delta Sigma (DS) chips may look better on paper. In practice, however, they are incomparable to R2R. The stated accuracy numbers of DS DACs are post modulation...

    DaVa FC-A1 a field coil contender

    Since our reference speaker uses a field coil driver, and knowing what that does, it would be so cool to hear it at the other end! I will have to consider this for the next iteration here.

    The Myth of Diminishing Returns

    Here is an example of a tweak that is small in both cost and the amount of real estate it occupies but yields a big result: https://www.lotusgroupusa.com/blog/mishap-equals-opportunity

    Are Transports Obsolete?

    What I like about the ritual leading up to the needle drop is that it brings my focus more into the present. It adds weight and import to the occasion of listening, even if it is all for one track only. So I view it as more of an opportunity than an inconvenience.

    The Myth of Diminishing Returns

    I posted this elsewhere on the forum in response to a particular post, but I thought it should stand in its own thread: My idea, "The Myth of Diminishing Returns" was arrived at after years of tweaking some "go for broke" systems. Simply stated, it goes like this: Each new bonafide upgrade...

    Review of The PranaWire Annapurna Collector/Platform at Audio Exotics Hong Kong

    Passive components have intrinsic non linearities due to their architecture and choice of materials. This is further exacerbated by their relationship with boards and other devices. As frequency rises electromagnetic coupling increases and causes further non linearities to occur. All devices...

    Review of The PranaWire Annapurna Collector/Platform at Audio Exotics Hong Kong

    " The sense of intimacy, pace, rhythm, texture, unfettered dynamics and emotion is unlike anything previously experienced in spite of full assault on all types of noises at Divin Lab. This is a new category of product that qualifies as a “cutting edge game changer” akin to Dalby Pirueta Record...

    What does it mean when people describe Digital as Sounding like "Analog"? Best term?

    There appears to be no objective way to compare the digital verses the analog versions of a recording as the source file and source vinyl are processed differently. So from the very beginning they are different. The closest one might come would be to listen to the vinyl and then send the vinyl...

    Furutech or Oyaide Silver - Gold - Rhodium (inc NCF from Furutech) - Palladium - Beryllium - Sound Signatures

    We are the US importer for Oyaide. In my experience biggest bang for the buck will be with the P and C-004 male and female connectors. These are made from beryllium copper with Platinum and Palladium plating plating. They present a great density of information and, at the same time, are smooth...

    Audiophile Fuses

    My apologies. I read the quote rather than the post. I have now read it. So sorry that happened. So you never got to hear the Ultimate Premier?

    Audiophile Fuses

    I have not tried that. I would use TA-32 because it is 1/3 the thickness of the TA-102 and wraps around a small circumference. Though you won’t get a reading with a multimeter, these materials are very slightly conductive so you do not want them to come into contact with any live traces. I don’t...

    Audiophile Fuses

    Hi Ricardo, Here are before and after photos: Mishap Equals Opportunity (link to my blog on the topic) I have yet to experience using too much TA-102 in this fashion. I also have it all over my system in various places. It is under the lids of my amp, preamp and phono stage. It is...

    Any one using Acoustic Revive devices or Acoustic System Resonators?

    We have documented that some small percentage of people do not hear any difference with the RR-888 Ultra Low Frequency Generator while at the same time others report significant improvements. When we first demo-ed them at Rocky Mountain Audio Fest we had it on a jury-rigged shelf on the side...

    Audiophile Fuses

    Hi Richard, To be clear I did not blow an Ultimate Premier. I blew an Ultimate, but through no fault of the fuse. My amp does not have an on off switch. I got lazy and unplugged and replugged it from the IEC end, which is not a wise thing to do in general, The ground pin of a NEMA wall plug...

    About Us

    The Lotus Group grew out of Joe Cohen's obsession with coaxing highly refined sound from high end hi fi systems – an obsession that has not slackened since the beginning. I began building my own cables in the late eighties, experimenting with various designs often getting better results than...

    Audiophile Fuses

    You would think that straight wire without any fuse should sound better than with any fuse at all, just as you would think that a power cable direct from the wall should be better than with any power conditioner placed between the wall and the component. But, I think it is a matter of whether...

    Audiophile Fuses

    I have just received two of the Audio Magic Ultimate Premiers which replaced the Audio Magic Ultimates, the previous highest level fuses from them. These are beyond spectacular. I have only fried one of their fuses, but it was my fault not theirs. Highly recommended.

    Bocchino US Mains Socket

    The first Cloud9 Power Conditioner has been built.You can see it in our banner ad in the cable forum and vibration control forum. We did not build according to the rendering that I posted here, as that design had too many complications in it. We are in the process of building the second Cloud9...

    Any one using Acoustic Revive devices or Acoustic System Resonators?

    One thing that is very interesting about the RR-888 is that, even though it is not connected to the system in any way, its performance can be enhanced by the addition of various tweaks. The most basic of these is using an outboard linear power supply to replace the wall wart that it comes with...
