| Quatre dg-250 amplifier The early gain cells were best with 8 ohm speakers in terms of stability. If one blows up you may have hard time sourcing transistors. Check this link:http://www.diyaudio.com/forums/showthread/t-4255.html | |
| Fed Ex Ground Shipping Woes When you fill out a Fedex Ground slip it asks if you are shipping to a residence or business. If you check residence, the package usually goes through their Home Delivery service. In these parts there are separate terminals for Ground and Home Del... | |
| Beatles 1 sound quality? The vinyl version sounds like a crappy CD. Thank the boys at Capitol Records. | |
| 7.1 speaker set up recommendation Check out the home theatre equipment reviews over at iar-80.com. This will give you some ideas about speaker characteristics and placement considerations for a 7.1 system. Then decide what to buy. | |
| Power Plant Premier making sound worse? I own a PPP purchased 2/07. My APL/Esoteric definitely sounds better straight into the wall - more lucid and dynamic each time I tested it. Perhaps it has something to do with the R-core transformer.Through experimentation, I found that on a good ... | |
| anyone remember the RGR preamp from the early 80's I owned one of these. Very poor construction quality by today's standards - used cheap strip RCA connectors. As I recall, the designer kept changing the tonal balance of the unit as noted by reviewers. It had detachable circuit boards inside. It h... | |
| Confused by ICE applications Amps with high damping factors can cause a reduction in perceived bass in speakers with limited low frequency capability. For example, when the midrange driver is also handling the lower frequencies.The was an article at 6 Moons a while back discu... | |
| Will new Class D trump a vintage Class A/AB? Few amps can handle zero ohm territory. The class D implementation distortion signature may or may not be to your liking. Many class D amps come in small chassis and have a switching power supply built in to the amp module. Big chassis class D lik... | |
| Passive Biamping? You may need attentuators on one of the amps. Far less than a 1 db imbalance can be enough to skew the tonal response. You could use a single amp with jumpers on the speakers as a reference point for the "normal" tonal balance. On some speakers, t... | |
| H20 Revisited One important point with the bypass caps. Unplug the unit and discharge the big electrolytic caps before working on the unit. There is significant voltage waiting to zap you.Also the stock binding posts are nickle-plated. Just about any other Card... | |
| H20 Revisited I am still using my H20 and am very happy with it. There are lots of Icepower amps around. Most use Icepower modules with a built in switching power supply and have a very small chassis. The H20 uses a large linear power supply and large chassis. ... | |
| Power Plant Premier vs. Hydra V-Ray Comparison I don't think my fan has ever gone on but my total load is problem < 400 watts. Never noticed any heat to speak of unlike the P300 which could probably cook bacon. | |
| Power Plant Premier vs. Hydra V-Ray Comparison You should test each component individually with both units. I have found the Premier generally improves things but specific components could prove to be an exception. | |
| APL NWO-2.5T A Review of a Classic CD Player EarflappinI have not found the 3.0 break-in to be of the trying nature described by some 2.5 series owners. It started out great and just gets more so. I found the Isotek disc helpful for redbook and burned a DVD-A from it.In rethinking your room ... | |
| Holy Moly Blu-Ray Disc Players below $300 I have both PS3 and XBox HD players. I rent mostly. I cringe everytime I encounter a dual format HD DVD disc since I have encountered a number of defective ones. I have no use for dual format other than the fact that the DVD side works when the HD... |
