| verdict on class D amps? Careful circuit design & quality parts will always produce a better sounding amp and this applies to both digital & analog amps. Some cheaply manufactured digital amps are a good choice for subwoofer duty since they deliver more power for ... | |
| Dodd Preamp Question How good is the Dodd compared to other modern tube preamps, maybe for example the Modwright? It at the very least must have a low noise floor because of its battery supply. | |
| Threshold S300 Power Amp The amp is way ahead of its time even though it was designed in the eighties. Very refined, transparent and powerful. By todays standards it still is extremely good sounding, Nelson Pass is a genius but also takes pride in his designs and workmans... | |
| McCormack SMC Audio upgrades: how good are they? Chiho, the upgrades offered by Smc Audio are superb. I think your in a position that alot of audiophiles envy owning a DNA 125 Gold revision. You might find an ss amp that has a fancier more bullet proof chassis but it will be near impossible to b... | |
| "D" amps, general discussion who's 1 and why? I'm still a big fan of PS Audio's HCA-2 especially for what it can be had for at current used prices. It uses an analog power supply (highly desirable and has only two gain stages (no B&O Ice Modules here). It was a Stereophile Class A product... | |
| Saved by a Bose Wave radio There is nothing wrong with Bose. I have owned some of their speakers years ago & no they are not the ultimate sound but enjoyable devices that cut through the bull and deliver good sound for a reasonable price. I imagine the Wave radio is als... | |
| What might cause LOUD hum in a Conrad Johnson pv6 Randallvar, is the hum coming from your speakers or is coming directly from inside the preamp? | |
| What might cause LOUD hum in a Conrad Johnson pv6 This is one explanation: Microphonics. Try tube dampers. | |
| Need tube advice You don't have to buy tubes from CJ but in my opinion it is a safer purchase because of their high standards and good reputation. CJ may charge more for their tubes but if cost is an issue you can safely buy on-line if the company or individual ha... | |
| New preamps making new claims. I don't think that circuit design in itself has changed that much over the past 25 years & a good but older design is often viable for years to come but what is better now is the parts. When you send an older unit in for an upgrade, it is the ... | |
| Opinions on Music Angel or Pacific Creek Tube Int. I will give some input on the Music Angel/ Marantz 7 preamp only not the integrated on this older thread. Maybe it will help others who are considering buying this fine preamp that is still currently in production. First of all this is quite a hef... | |
| Noise coming from tweeter when amp get turned on Have you tried disconnecting the preamp from the power amp. Leaving the power amp on & only the power amp, do you still get this low level hiss? | |
| Someone school me on this stuff Unlike most integrated amps, separates give you the option of trying different preamps or power amp combinations to reach the desired sound. I have had a few integrated amps and was not completely satified with them. However integrated amps are sp... | |
| Popping from tube integrated amp Have you tried reinserting the stock (Chinese) tubes to see if the problem continues? | |
| Old power amp with newer preamp? There is nothing wrong with using an older power amp with a new preamp. Take for example the highly acclaimed Hafler D200 & DH220 amps from the eighties. In a second system I'm using a new tube preamp (Audio Experience V2R) with the Hafler DH2... |
