| how to get good sounding copies of CDs Some CD players, mostly older ones (weak lasers), have problems playing CDRs (less reflective).Rega Apollo might be one of them. I found info about it in another Audiogon thread:"In John Atkinson's recent testing of a Rega Apollo CD player he note... | |
| Any Newer Class D Mono Amps On The Horizon? I have Rowland Model 102. It's Icepower 200ASC, rated 200W/4Ohm. I paid $1500 while Bel Canto S300 (same module)was $1600 and Channel Island D100 was close to $2k. Channel Island is based on Hypex modules and sounds a little bit different. | |
| How to make sound less detailed with warmth? Tube amp, Cardas cables, room treatments.I'm surprised that you want to loose details - thin blanket over speakers will do. It will kill both details AND brightness.90% of people want warm and detailed sound which is very difficult to achieve. I p... | |
| Anybody hear Murano ICE amps? Mapman - When I bought Rowland 102 I found opinions of others who tested Rowland 102, Bel Canto S300 and PS Audio Trio. My decision was also based on Rowlands reputation and price lower at the time than Bel Canto. One of reviews of Bel Canto's S30... | |
| Anybody hear Murano ICE amps? Don't wait for the rainy day - Icepower doesn't sell to private people (only to approved manufacturers). Minimum quantity is about 1000 pieces (792 pcs for 200ASC). Modifications to module voids warranty - just wonder if companies have "factory ma... | |
| what advantage to switch mode P/S vs standard P/S Shadorne, you're right - they might produce EM/RF. Everything is in the hands of designer (and layout designers). I was trying to show best case advantages od SMPS. Unforunately companies often use SMPS topology only to reduce cost making often w... | |
| what advantage to switch mode P/S vs standard P/S 1. SMPS is regulated while traditional linear PS isn't. Likely to hold voltage better at loud passages.2. Current pulse response is faster unless linear supply has expensive slit foil (non-inductive) capacitors etc.3. Higher switching frequency is... | |
| Do amplifiers deteriorate if not used? SMPS = switcher (switching mode power supply).Follow Gs5556 advice and use Variac. It might not help if you have SMPS (not likely) but will save your amp otherwise. | |
| Class-D amps - a different re view Ar-t - I have the smallest of the series and 23.5V on terminals. To deliver 5x more power they need voltage around 52.5V. I think it stays below safe level of 60V but agree with you that this might be of concern. I don't touch speaker connectors b... | |
| Class-D amps - a different re view Ar_t Icepower uses full H-Bridge of 4 Mosfets switching direction of the speaker between +VCC and GND. In spite of VCC/2 on the speaker terminals, voltage between terminals is zero. The only disadvantage of this scheme I know is that you cannot br... | |
| Do amplifiers deteriorate if not used? Yioryos - I just assume your ML27.5 has linear power supply. If it has SMPS it will not do anything (start) to about 70VAC then it will put full operating voltage on the caps. | |
| Class-D amps - a different re view Muralman - people are often confused and becuse they like guitar sound on 30W Vox (remeber The Beatles)with tubes and no feedback (high thd) and want their home system to be like that - close to real performance. Home system of course should not c... | |
| Do amplifiers deteriorate if not used? Gs5556 - I suspected it has something to do with overvoltage. I read somwhere about hydrogen release (and explosion) in dry aluminium electrolytic caps.On the other hand datasheet of the few brands I checked show shelf life only 1/2 of load life a... | |
| Class-D amps - a different re view Muralman - I have no experience with high end DAC circuits but my Benchmark has surprisingly clean and transparaent sound. Part of this is due to anti-jitter circuitry. Jitter produces sidebands of very low amplitude (typicaly -80dB) but very audi... | |
| Class-D amps - a different re view AtmasphereQuoted current - as I said before is the peak current and has nothing to do with average power. It is used to show how well amplifier can respond to impulse. Internally my 200ASC Icepower can deliver 48V to speaker what would make at 3 O... |
