| DAC volume controls I have Benchmark DAC3 to Benchmark AHB2 power amp. It sounds wonderful and has digital volume control for digital signals. Previously I had Benchmark DAC1, that had analog volume control. DAC3 sounds way better, but it is most likely because of... | |
| 1st SACD Purchase For audio playback, I can use XLR or optical from the 901 to the 2600. I am doing some A-B testing to determine which DAC is better for CD playback, the 901 or 2600.MVP901 will output optical , but most likely it will be CD layer only. Your A-B ... | |
| Sub $1k Power Conditioners? Any Assistance Appreciated... I have Furman Elite-20 PFi. I bought it used for $650 many years ago. It has good filtering and very tight non-sacrificial over/undervoltage protection. PF in the name stands for power factor correction. Typical gear draws current from mains i... | |
| How do you power EU items? and how to ship an item to USA? talkskiwon, I would get the rest of the gear first. There are basically two camps - accurate presentation camp and pleasant coloration camp (warm sound etc). I belong to the first camp with Benchmark DAC3 HGC and Benchmark AHB2 power amp. Benc... | |
| How do you power EU items? and how to ship an item to USA? talkskiwon, there are two types of USB transmission to DAC - synchronous and asynchronous. The first one relies on computer to create timing while asynchronous USB sends data in packets and DAC recreates timing with its own clock. Most of the ne... | |
| Do Ethernet cable Cat8 DH Labs need burn in I'm not sure why you expect any change. You're just sending data - changes in timing or voltage level (within reason) don't affect anything. | |
| Damping Factor - Interesting article @atmasphere That's how they describe this car amp:Speakers and subwoofers change their impedances depending on what frequency note is playing. Normally, an amplifier will change its output power according to what impedance it senses. The Constant... | |
| How important is a Linear Power Supply Versus a Switcyed one? I don't know. Perhaps SMPS is in standard production while LPS is not (requires modifications). | |
| Damping Factor - Interesting article It is possible to make amplifier like that, but I found only car amp that delivers constant power:https://www.crutchfield.com/S-W0uT7l6IaIv/learn/amplifier-power-labs.html#:~:text=Constant%20Power&text=Normally%2C%20an%20amplifier%20will%20cha... | |
| How important is a Linear Power Supply Versus a Switcyed one? Any power supply introduces noise. Linear PS is also switching (at max voltage). The question is how much noise? They had to have a reason to implement SMPS. Switchers are usually used for their efficiency when high currents are required or fo... | |
| Damping Factor - Interesting article but the low DF will in many cases be better.How low? For electrical damping of 8ohm speaker difference between DF=10 and DF=100 will be like 6.8ohm vs 6.08ohm (assuming 6ohm as resistance of 8ohm coil). It is about 12% difference in breaking cur... | |
| Buy a new CD transport? Don't touch it, if it works perfectly. The only thing, sound-wise, you might gain is lower jitter - most likely inaudible, since Benchmark DAC3 has very strong jitter suppression. | |
| How important is a Linear Power Supply Versus a Switcyed one? Both are switching producing high frequency noise, but SMPS done poorly can be really bad, much worse than linear PS. On the other hand SMPS can be much quieter than linear PS if designed for low noise (zero current, zero voltage switching). Jeff ... | |
| Any alternative to Radio Shack sound level meter? mijostyn, thank you. I know there is something wrong with my room response, but I will fix it later. At least I have tool. My room is too reflective. I don't hear any particular resonances but listening louder makes sound less clean. It is mos... | |
| Damping Factor - Interesting article Every amplifier has some feedback. Even emitter resistor is a form of local feedback. The problem with global feedback is, that it corrects with a delay (phase shift from input to output). This delay produces overshoot in time domain (odd harmonic... |
