| Purifi Class D: Junk? No, you are reading the spec of the amp without a buffer. The stock Hypex generic buffer board that is sold by VTV has 47K to ground on each phase. This is in the buffer added mode. If you configure the board so the buffer is not in the circuit...... | |
| High end Class D amps? I brought my first proto of the mono IceEdge amps over to a guys house last year and we A/Bed it with his mono IceEdge amps from Mivera Audio. When we were listening to his amp the sound of the bass was rather "tubey" and I told him so. He said he... | |
| High end Class D amps? Take your Ncore amp and put a .1 ohm non inductive power resistor on the inside of the amp right at the binding post (in series with the post). Now the output impedance of the amp is at least .1 ohm.......so, listen to it again. Does it sound ex... | |
| High end Class D amps? Actually, you do not want any conductive material at all for a transformer bolt. Even a brass or non magnetic stainless steel bolt will degrade the sound compared to no bolt or plastic bolt. You want nothing conductive above, below or in the mid... | |
| High end Class D amps? As I keep saying.....everything makes a difference. There is no Class D sound. For instance.....every amp that uses the Purifi modules will sound different from each other. It is not just whether the power supply is linear or switching.....for a g... | |
| High end Class D amps? Teo_Audio,This is not my experience. I have bought IcePower modules and sold amps using modified modules. I am now modding Purifi based amps. The only thing you lose when you modify is the warrantee from the manufacturer. Most audio companies don’... | |
| Why I enjoy my Luminous Audio passive unit, vs an additional gain stage ( preamp ) I have never heard of anyone except for Atmasphere that claims that balanced cables sound the same. He says it must be to the AES 48 "standard". I guess all other gear then is not up to his "standard" except the gear he sells. However, I have seen... | |

The versions with the discrete op amps and discrete regulators are bet... | |
| Cube Audio Nenuphar Single Driver Speaker (10 inch) TQWT Enclosure Now this will blow your minds! The speakers have binding posts. These WBT posts are very good but not as good as hardwiring. But what is really not good is the input tip jack on the speaker driver.....looks like it only takes a banana plug. If you... | |
| Removing a ZERO from the price of amps I have been manufacturing products and modifying products for over 42 years. I have less than 1% unhappy customers. This includes over 100 modified CD, DVD, SACD and Blue Ray players (most of which were stock players that were sent in to mod so th... | |
| Removing a ZERO from the price of amps Here is a comparison of the Purifi based 2 channel stereo amps from VTV and NAD:Cost: The C-298 NAD is $2K plus shipping and maybe tax. The VTV stereo amp is $979 with free shipping (30 day money back) with the stock Hypex single dual op amp per ... | |
| Discussion of Class D Amps Application & Experiences The VTV Purifi based stereo amps start at $979......$1335 with Sparko labs Pro discrete op amps....that price includes delivery, 2 year warrantee and 30 day money back. Unbeatable value. These are the amps that I will mostly be modding....for th... | |
| Discussion of Class D Amps Application & Experiences It is all about trusting yourself. Back in the late 70s my friend knew the owner of Sumiko (who imported Supex cartridges, among other things)....so he borrowed 10 brand new Supex cartridges and we mounted each on on a universal head shell and put... | |
| Discussion of Class D Amps Application & Experiences Some people have direct experience and others just have opinions. It is universal (to those that have listened and tested on their own system) that larger power supplies with lower impedance sound better.....even when using less than one watt.Yes,... |
