| Understanding Gain in the ARC Ref Phono 2 SE Excellent points by the others.I'm guessing my volume in low gain on the ARC is due to running BAL (51dB) compared to BAL on the Rowland Cadence at 64 dB. On to something there? Yes. As ActusReus indicated, 51 db of phono stage gain is too little ... | |
| Coincident Dragon Amplifier Hi Jim,Thanks for your interest. I still haven't gotten around to having the McMurdo Silver cabinet refinished; it's a low priority for me right now. Also, I don't envision selling any of my sets in the foreseeable future. Since you are relatively... | |
| Current amp vs Voltage amp 05-10-13: Atmasphere I wonder what happens if one listens to nicely produced music, say a big band with lots of brass and high frequency energy live at 105DB? Is it as comfortable as listening to the no NF tube amp at the same level? Its a fair qu... | |
| Need help with splitting XLR OUTPUT The Aphex unit suggested by Tls49 does look like an excellent solution, if you don't mind its cost.Regarding the original question about using cable splitters to split four ways, it depends on the output impedance of the sub output of the Meridian... | |
| Current amp vs Voltage amp 05-09-13: SwampwalkerI'd love to hear Atmasphere and Almarg comment about how that type of amplifier's inherent electrical characteristics interacts w speaker loads.Hi Michael,I'm not especially familiar with Class D amplifiers. But in terms of ou... | |
| Which headphones?? How do you tell a headphones "sensitivity" rating?Sometimes it is explicitly specified, as sound pressure level (in db) for a 1 volt input.In other cases it may be specified as SPL for an input of 1 mw (1 milliwatt, which is 0.001 watts). To conve... | |
| Current amp vs Voltage amp I think that Bombaywalla may, somewhat understandably, have misconstrued Bruce's situation. AFAIK he hasn't had nearly as much interaction with Bruce and his speaker/amplifier concerns as I (and Ralph) have had. Bruce is certainly not in "speaker ... | |
| Current amp vs Voltage amp Bifwynne, by adding negative feedback to an amplifier you do indeed move the amp towards the Voltage Paradigm. This is because as you surmised the 'output impedance' is lowered. I paraphrased the term because it is misunderstood however, and that ... | |
| MC Phono Pre Gain It looks like the sensitivity of the M80 is 1.5 volts, as indicated in the manual here, which is neither particularly high nor particularly low. The Aikido preamp appears to have existed in a number of different variations, using a number of diffe... | |
| MC Phono Pre Gain I second several of the comments that have been made to the effect that not enough information has been provided. Most importantly, what is the gain of your line stage preamp, and what is the sensitivity of the power amp (i.e., the input voltage t... | |
| Current amp vs Voltage amp Hi Bombaywalla,Yes, agreed.As you certainly realize, any design involves a zillion or so tradeoffs and competing considerations, but it's still striking how some speakers can perform well with very diverse kinds of amplifiers, while other speakers... | |
| Classe CA-100 stereo vs bridged Hi Peter (Csontos), First, let me repeat what I said:I wouldn't be surprised if the sensitivity increases by 6 db (i.e., you would have to reduce your volume control setting by 6 db, to achieve the SAME VOLUME [emphasis added] as in stereo configu... | |
| Classe CA-100 stereo vs bridged My guess is that the 350W/600W 8 ohm/4 ohm mono ratings, which are shown in the manual and in the fancily printed part of the brochure, are accurate. The white spec sheet showing 200W/400W, that is part of the brochure pdf, I suspect is a document... | |
| DIY question on a preamp problem could use help... Bill, I took a look at some rear panel photos of the Zoe. Although it's hard to tell for sure, it looks like although the two pairs of main output RCAs and the two pairs of input RCA's that are adjacent to them are the type that are isolated from ... | |
| Current amp vs Voltage amp Unsound,If the output impedance of the amplifier is a good match for the particular speaker, the output of the amplifier WILL adapt appropriately.Think of the amplifier as an amplifier having zero output impedance in series with a resistor whose v... |
