labjr Posted October 29, 2014 Share Posted October 29, 2014 Passive components have to nothing to do with bit streaming or DoP? Most of the sales pitch looks like exaggeration written by Gavin trying to suck in unsuspecting buyers with little knowledge of DACs. I remember when he was saying DSD128 has "128 times the resolution of CD!" Link to comment
kravi4ka Posted October 29, 2014 Share Posted October 29, 2014 Gavin is the real star there, I expect much more from him... "128 times the resolution of CD!" is a good one though. Link to comment
rdsu Posted October 30, 2014 Share Posted October 30, 2014 OK, but that directly contradicts what I quoted from the just-updated GoGo page... that bitstreaming is a feature confined to the Soul, and mentioned explicitly as a point of upsale. And furthermore, confined to the Soul because "passive components" need to be installed to "improve the DAC circuit's conversion efficiency". How can a mere firmware upgrade possibly remedy that? Once again LH needs to get its story straight. This will clarify these things: https://www.indiegogo.com/projects/geek-pulse-high-res-audio-for-your-desktop Link to comment
Superdad Posted October 30, 2014 Author Share Posted October 30, 2014 This will clarify these things: Down in the red section of the matrix it lists the "Lint Output" of the versions. Funny, around my house only our clothes dryer has a lint output. UpTone Audio LLC Link to comment

rhmmmm Posted November 1, 2014 Share Posted November 1, 2014 Who is going to back the Geek Soul? Thoughts? Personally, I wish they had started with an option to that type of unit, but I guess it was way out of the scope of the original campaign. This seems to have been a learning process for the company in that people will pay a lot more than they had previously expected. They published the stats on which models were purchased and by far, people were either buying the base model or the maxxed put XFi model, with low number buying anything in between. Link to comment

rhmmmm Posted November 1, 2014 Share Posted November 1, 2014 Me too! So would I but I doubt you'll see it much. They're giving away some of their "secret sauce" here. Very cool of them to do. I could imagine only a handful of companies might ever do this. Most likely the "social" ones you see like PS Audio or something. Makes you wonder what kind of tricks are in the LH DaVinci DAC...

I could imagine only a handful of companies might ever do this. Most likely the "social" ones you see like PS Audio or something. Makes you wonder what kind of tricks are in the LH DaVinci DAC... These are basic design principles. It's being done extensively in IC designs and packaging designs as well. For designers, this is a common knowledge so I do not see any secret sauce being exposed there. With that said, I want a Soul tube in a Pulse chassis, i.e. leave the LPS separate. The Soul chassis is not for headphone or desktop purposes so there is an opening there for a tube desktop version that most likely will happen some other time. Link to comment
labjr Posted November 2, 2014 Share Posted November 2, 2014 I think an onboard supply has advantages too. Multiple secondaries on the transformer for separate isolated analog and digital supplies. Bipolar supplies for analog circuits. Though I suppose it could be done separately too. Link to comment

longbowbbs Posted November 2, 2014 Share Posted November 2, 2014 I am writing the review for Headphone.Guru | Headphone.Guru on the Geek Pulse X-Fi and the LPS. Look for it in a couple of weeks. Here are some current shots from the listening room... I am a backer of the campaign and was for Geek out as well. I have been (im)patiently waiting for months to get the unit in house. It has been well worth the wait. It will be a real competitor at it's stated retail price. At the current IGG price it is a crazy good deal. Upgradeus Interruptus.....

I have several battery supplies that should work. Usually end up with a high current supply with a 4 pole Jensen cap and filter network. A little inductance and a lot of energy storage seems to work well. As far as current it is hard to compete with a battery. I was changing a connector on a small battery supply once. While dressing the leads got a knife across the +/- and got the pop. Looked and a chunk had vaporized from the knife blade.

RobbieC Posted November 6, 2014 Share Posted November 6, 2014 The Geek Soul upgrade has been selling out very quickly. I was watching on Indiegogo the moment the first round of units were made available and they (30 units) sold out in minutes. It seems like an interesting product. But, it is being sold at a significant increase in price compared to the original campaign prices for the Pulse X and Xfi. For instance, iirc the Pulse Xfi was originally offered at about $600. Then for a more direct comparison to the Soul Xfi you need to combine an LPS offered originally at about $300 to the Pulse Xfi for a grand total of $900. However, Light Harmonic is offering 120% of your campaign backing as trade in towards this upgrade perk. So, now you have about $1080 in credit towards your Soul upgrade. The Soul Xfi is being offered at $1700 for a difference of about $600. What exactly does this $600 buy you? A nice (arguable) T6061 chassis? Ok. What else? Bipolar power circuit? Ok. But everything else is supposed to be nearly identical since parts are to be essentially shared across products like between a Toyota Camry and a Lexus ES. The Camry/ES comparison admittedly isn't a very good analogy in this case since there are many, many more cosmetic parts on a car, both interior and exterior, that can affect a buyer's sensibilities than there are on a piece of audio equipment. That and Lexus offers a better warranty helping to justify a premium for what is essentially the same car whereas the Pulse and Soul have the same warranty offering. Rob C Link to comment
Superdad Posted November 6, 2014 Author Share Posted November 6, 2014 A beautiful Soul... Well at this point it is just another concept. It might take them another 8+ months to get it into production and out the door. They may be in for a rude wake up call when they find out what it is going to cost to have that cute chassis produced. Machining it from a solid block is will cost a fortune, and getting the finishing right on all those surfaces is going to be a big challenge. And forget about it being a multi-paneled affair. I just don't get LH anymore. They have a million dollars or more and the entire continued existence of the firm riding on executing well and delivering pre-paid products, yet they hire a 23-year old graphic designer 3-months out of art school to do the industrial design for their most important new product. I don't wish a train wreck on them, but I am making so popcorn to watch the show… P.S. Does anyone know where the headphone jack and volume control are going? UpTone Audio LLC Link to comment
