| Purifi Class D: Junk? My Audio Research sp-16 has 240 ohm output impedance into Bel Canto ref1000m amps. These have 100kohm input impedance with the BC input stage versus 10k ohm for the stock Icepower module used solo on the ref1000 model. That is to provide good perf... | |
| Power strips- too many choices I use a power strip mainly for surge protection to protect my gear. Also does some power conditioning. Then suitable wires from there into gear. But not for power amps. Only line level gear. Preamp, DAC, step up xformer. Power amps or even... | |
| Power strips- too many choices Power strips must use good wire. | |
| Purifi Class D: Junk? Well if that’s the spec that would certainly help explain the result. Does not mean it’s junk just that there is a system mismatch. Inexpensive Class D amps usually just provide a stock circuit in a box I have an $80 Fosi Class D integrated amp (w... | |
| Any Ohm Walsh owners using tube amp? You could try adding a powered sub using something like a mini DSP to take things to the next level. That would open up many options for the main amps if still needed. | |
| What is Floyd Toole saying about extra amplifier power and headroom? Sounds like things are going well and as they should. Your main amp is not working anywhere near as hard covering only down to 90hz. It’s like putting the same size engine in a much smaller car. Also the sub is better cut out to handle the lowest ... | |
| Any Ohm Walsh owners using tube amp? You certainly can use a tube amp. Those I am aware of that have seem to then lean towards adding a sub. They are not explicitly designed for tube amps but not to say it might not work well in some cases. I have the the exact same model. Personally... | |
| Do you, or did you, have Audiophile buddies that you shared music, gear, times with? Here and there but in college I worked part time at the local Tech HIfi and sold systems and gear to a lot of others in my dorm. Having a good hifi in your dorm room was a big thing back then and a lot of time was spent together on the topic. That... | |
| Sorry, it’s not me, it’s you? I had a substandard preamp for a number of years and didn’t realize it until someone here recommended I upgrade. They were right! | |
| How can music be sad? Music either resonates with ones senses or it doesn’t. That is just one possible way enabled by our ability to hear. All our life experiences are made possible by ones senses. | |
| What is Floyd Toole saying about extra amplifier power and headroom? Yes but the topic was total amps not power so # amps per channel x 2. Class D amps are most efficient by a large margin. That’s their biggest claim to fame. So they are inherently better at delivering more power and current than others. Just like ... | |
| What is Floyd Toole saying about extra amplifier power and headroom? My understanding from quick read is the minidsp device can function as an active crossover and it’s internal implementation is digital. Crossover goes between pre amp and amp, both analog. So the digital crossover must then first do Analog to digi... | |
| What is Floyd Toole saying about extra amplifier power and headroom? Sounds like you are going plenty loud off a pair of stand monitors so more power may be moot but more current may still be a ticket to better sound.Two potential issues with trying to go louder:1) the old heat/compression factor that could make it... | |
| Ohm Speakers Model B The web site indicated they were hit hard by Covid in NYC, backlogged and may be harder to get hold of but if you sent money and did not receive the product I would email or call or whatever is needed to get through. I would have to think they wi... | |
