| Would love some feedback / Denon DL-S1 / phono match / cart recomendations The real issue is that the DL-S1 has an output of .15mV with an internal impedance of 40 ohms. There is no step up transformer that can do it justice. If you raise the gain enough, you load the cartridge too much. You have to use an active stag... | |
| On Step Ups and the Importance of Managing Gain I agree with folkfreak, which is why Bob's Devices now has the SKY 10. The SKY 10 has step up ratios of 1:10 and 1:5. The 1:5 ratio was selected to meet the needs of those phono stages that have high gain settings of around 60 dB. | |
| Audio Research PH5 Phono Preamplifier Input Clipping Problem I refuse to get into a pissing contest with a skunk. Done here. | |
| Audio Research PH5 Phono Preamplifier Input Clipping Problem I have had no luck with using a SUT with the ARC-5. The gain of 57.5 is difficult to work with. Almarg is correct. However, if you look at the signal to noise ratios of active MC/MM phono stages, you will find that the signal to noise ratio usi... | |
| VPI MOTOR PULLEY ?? yeah, i used to live in Wilmington, NC but got tired of the heat and humidity. Moved the family and the company to Montana. Back on topic, I never got an email from autospec. He must have been talking about someone else. | |
| VPI MOTOR PULLEY ?? I am in Billings, MT and have a shop that is by appointment only. I mostly do mail order and audio shows. | |
| Audio Research PH5 Phono Preamplifier Input Clipping Problem Using a step up transformer of 1:20 will give you an output from the cartridge of 5.2mV, about the same as that of a MM cartridge. The PH5 overloads at 70mV and typically if you allow for about 10x the input voltage for peak overloads, you have e... | |
| VPI MOTOR PULLEY ?? and you don't even have to log in. you can email bob@bobsdevices.com or call at 910-612-8666. I will just need a photo of your pulley. | |
| VPI MOTOR PULLEY ?? HI This is Bob from Bob's Devices. I don't remember getting an email recently about a pulley, but typically I only need a photo to make sure you get the right part. VPI is not standard on their parts, even on the same table. If someone emails o... | |
| Koetsu RSP Sound Problem I have personally owned a Rosewood Signature Platinum (RSP) along with several other Koetsu Cartridges. I loved the sound of the RSP. After considerable use, I needed to retip it and sent it to Soundsmith for repair. I was extremely pleased wi... | |
| Naked Classic Platter I don't use a mat. Mine is naked. | |
| VPI 3-D tonearm I have use a Koetsu Azule on a 12-inch 3D arm. It sounds amazing. Prior to that, I had to use Damping fluid in a 12-inch metal VPI arm to get it to sound right. | |
| Table setup/help in SE WI The first thing you should do is make sure the surface the turntable and motor is on is level. Then make sure the turntable is level by putting the level on the platter and rotating it to make sure it is level in all directions. Then, the VPI jig ... | |
| Matching Koetsu Stone Body Platinum Cartridge The Denon 103 version of the A23, I Believe, uses HAUFE T-7883 transformers which have a 1:10 step up ratio. http://www.haufe-uebertrager.de/Daten/Datenblaetter/Datenblatt%20T7883%20013120.pdf | |
| Matching Koetsu Stone Body Platinum Cartridge I have personally used the Azule and Tiger Eye, along with the Rosewood Signature Platinum. My favorite is the Azule. Having also listened to several of the rosewood signature platinum cartriges, I find each one to sound slightly different. So I w... |
