| Looking for some new floor standing speakers As @chorus mentioned, take a look at the GR Research options. I had the GE Triton2+ and got the upgrade itch. After stumbling across Danny Ritchie's (owner of GR Research) videos about speaker technology and design, I decided to build a set of NX-... | |
| An audio rack that really does make a difference. I bought a SolidTech rack earlier this year. I'm not sure if it really makes THAT much difference to the sound, but it's very sturdy and looks great. I like the hi-tech look and it fits well with my decor.I also think the Timber Nation racks look ... | |
| High end Class D amps? There are class A/B amps that have been designed to output very high current levels at the expense of cost and weight, and thus far, class D designers have chosen to focus more on the mainstream market where current demands are not as extreme. But... | |
| High end Class D amps? George - You've brought up this notion of EPDR in several class D threads, but haven't explained how it relates to class D. This is a term that was made up by a Stereophile reviewer to try to explain why linear amplifiers had a hard time driving s... | |
| When does my class Atoll IN200 A/B integrated switch from class A to class B? I think they are jerking you around. Eliminating the electrical insulating material between the transistor and heatsink will reduce the thermal impedance, allowing a bit more of the transistors heat to be transferred to the heatsink, but this does... | |
| Do caps stay "fully formed" even under minimal load? (SS) @gs5556 - that's not really true. The caps are charging when the rectified voltage from the transformer is higher than their current stored voltage, and discharging otherwise. With 60hz power and assuming a full bridge rectifier, the caps will ge... | |
| What does ‘balance preamp’ mean? GregM answered this fairly well above, but I'll try to add some more background and detail.In most home audio systems, the analog signal between devices (e.g. from your dac to your preamp, or preamp to amp) uses an RCA cable. This type of cable ha... | |
| When does my class Atoll IN200 A/B integrated switch from class A to class B? If you want to get a flavor for what a class A amp sounds like, you should keep an eye out for a Pass Amp Camp Amp. These are sold in kit form in the DIY Audio store for about $330, but regularly show up on the used market in assembled form for $2... | |
| When does my class Atoll IN200 A/B integrated switch from class A to class B? Yeah, there is no way that this amp is running 40w class A. To deliver 120w into 8 ohms, the amp probably has rail voltages of approximately +/- 46v. To deliver 40w RMS class A, you'd need a bias current of about 1.6A to allow the amp to delive... | |
| High end Class D amps? I think the Weiss op amps could be worth a try. From what I've read, these are the best discrete op amps available and have the ability to bias the output stage fairly high (adjustable with a small trim pot). I plan to use these on one of the inpu... | |
| DAC Choices - $5,000 to $7,000 I had an older Wyred 4 Sound DAC 2 and it just didn't work for me. It sounded dull and flat in my system - not engaging at all. I suspect the newer ones have improved a lot, but it could have just been a bad match for my system. I replaced it with... | |
| DAC Choices - $5,000 to $7,000 @electroslacker - I think my next step is to add the Gaia to my Terminator, although I agree that using a Terminator+ with an Iris would likely be a good solution. I've got my old preamp (Parasound JC2-BP) for sale. As soon as that's gone, I'll or... | |
| High end Class D amps? @ricevs - Thanks for the offer, but I think there is lots of low hanging fruit to focus on before attempting to modify the Purifi module. At some point, I might consider it. | |
| DAC Choices - $5,000 to $7,000 I don't have experience with some of the other DACs recommended, but I'm happy with my Denafrips Terminator. I look for detail, deep and wide soundstage, smooth and natural vocals (particularly female), and some meat on the bones in the low freque... | |
| High end Class D amps? @atmasphere -nice explanation. Thanks.@twoleftears - I actually think that 1KVA toriodal is undersized for a hi-end stereo Purifi amp. I've generally found that using a larger power supply improves the dynamics and authority in the mid-bass and re... |
