| Advice on 3 different system combination Your speakers are a very hard load for an amp, looking at the Stereophile tests. They need an amp that can give high current into 2ohm loads, it would be better to find an amp that can almost quadruple it's 8ohm wattage when it's driving 2ohms.Nei... | |
| what the best amps run revel salon2 stronger bass Tranhu hi, looking at this impedance/-phase angle graph, your speaker are not easy but not as hungry as some.You need and amp that can supply good continuous current from 20hz to 600hz which is all of the low and upper bass.Big push pull tube (>... | |
| Tube Preamp vs Solid State Yes that maybe better than the Schitt Mdemaio, at 10kohm also, but it has a not so useable 20 position switch smd resistor type VC, these can be a bit coarse, a 32 position would have been better.But it's 6 x the price of the http://schiit.com/pro... | |
| Tube Preamp vs Solid State Hi Mapman, only one that I know that is reasonably priced at $49 is this one but it only has 2 inputs [url]http://schiit.com/products/sys[/url]If you PM me I can give you an alternative. Cheers George | |
| Tube Preamp vs Solid State Thieliste Hi. Before you try/buy waist money/time on anything, try this.Your only source the Ayon S5 has a volume control, and it already has a highly regarded (by tube lovers) a low output impedance tube output stage which is a 6H30. This is just... | |
| DAC straight to power amp? Sorry ZM, I thought the volume control on the front would have done both head phone jack and rca output. If not then you could use still the headphone jack, as it is also a low 32ohm output impedance, though it may be a bit higher in output voltag... | |
| DAC straight to power amp? I believe the volume is controlled by the TEAC UD-501 Dac. I don't believe the computer controls the volume in this case, it just gives a digital output signal, coax (spidf) or optical (toslink)output to the Teac, the volume is then controlled fro... | |
| DAC straight to power amp? Zm hi.Your Teac has a wonderful low output impedance of 22ohms with 2v output, your Stratos is 22kohm input impedance and only needs 1.5v for full output.As you can see the Teac is a perfect impedance and voltage match, you can't ask for better, a... | |
| Tube amplifier to power Sonus Faber speakers? Here is the simulated load graph that the Ref75 was tested with (1st link) as you can see compared to the flatness of the FR graph (2nd link)black trace, That this amp is relatively flat but is already dipping at 200hz. But the simulated load at t... | |
| Tube amplifier to power Sonus Faber speakers? Hi Frontier1, your speakers though advertised at nominal 4ohms, is not showing the whole picture. As the lab test results show in the link, they have an amp hungry impedance with -phase angle load of 1.7ohms in the bass. They maybe efficient but t... | |
| Super-sensitive volume controls - remedy? Jafox, as I said above two posts back, they "can" be a negative. What is the output impedance of the component before them? and the input impedance of the component after them?. That way we can prove with math, it was a bad electrical impedance ma... | |
| Super-sensitive volume controls - remedy? As far as I remember the Redbook standard has always been 2v. Just look at the first players from Sony/Marantz/Philips.EG: Sony CDP-101 Marantz CD-73 etc. They all have 2v output spec, which is all that's needed to drive the majority of poweramps ... | |
| Super-sensitive volume controls - remedy? 11-23-14: GhosthouseDo attenuators like the Rothwells impose any sort of penalty related to sonic quality? Thanks. Hope this is of interest to the OP tooThey "can"' as they could introduce an impedance mismatch between the previous components outp... | |
| Super-sensitive volume controls - remedy? Minkwelder hi. Most sources these days have enough output on their own to drive amps into clipping and then some, so there is no need to add more gain and colouration from an active preamp.As Raymonda has said a passive preamp will do and probably... | |
| Do I really need a preamp? I believe even in Stereophile John Atkinson states 47k-51k input impedance has been an unofficial input impedance standard now for over 50 years for most home audio S/S products input resistances. Since it was made the standard for MM cartridge lo... |
