do i change the preamp or the speakers? From what I saw when I looked under the hood of either Odyssey Stratos/Khartago Monoblocs, is that each monoblock was a stereo amp that was bridged to make mono.Google disadvantages of bridging amplifers, it may send you in another direction.Cheer... | |
Which Amplifier for Sonus Faber Olympica 3 Speaker Although the Olympica II looks similar the lack of another bass driver could make it an easier load in the bass compared to the Olympica III. The Lux 590 class A intergrated is a nice amp and it looks like it can push current as well, as from what... | |
Which Amplifier for Sonus Faber Olympica 3 Speaker That's what I said, out of the two the Hegel is the better option, but now that the test state the speaker is really a 3ohm design and has is a 2.6ohm load for the bass(100hz) and an amp sapping EPDR of 1.7ohms at 81hz Then even this amp though it... | |
Which Amplifier for Sonus Faber Olympica 3 Speaker DTC this may be true for the cheaper SF's but doing some more searches reveals the opposite, that the Olypia 3 are really a 3ohm design and has 2.6ohm dip at 103hz.And at 81hz it has an EPDR of just 1.7ohm load to the amp.Sorry but this model is a... | |
Which Amplifier for Sonus Faber Olympica 3 Speaker I can't find impedance/ phase graphs on yours but: Typically the Sonus Fabers I've seen the impedance and phase graphs of have been very difficult in the bottom end to drive, even though they are efficient. They have needed amps that can do good c... | |
Amplifier Voltage and Step Down Transformer It won't matter too much if the amp is 120v and the transformer is 110v. If it were the other way around then it would matter, as the heaters could go over voltage and the caps also, if they were run close to their voltage max.As for the rating (w... | |
First foray into Class A amp -- recommendations Yes the XA-30.5 looks to be a nice one and he's asking for offers, $2500 should be a nice price if he accepts.http://app.audiogon.com/listings/solid-state-pass-labs-xa-30-5-class-a-power-amp-mint-condition-remaining-warranty-2014-08-20-amplifiers-... | |
First foray into Class A amp -- recommendations You'll hear the difference if you can listen to a pair of Parasound JC1 monoblocks, as you can up the class A from 10w to 25w while listening with a switch on the back. And yes the 20w class a sounds much more "richer" compared to the lower settin... | |
What's the greatest bargain in SET these days? Charles just found some one who can explain why R-Cores make for very good output transformers, for triode SE amps here's what he said."Actually they appear to work and sound very well. Maybe they are not so popular because you get lower inductanc... | |
What's the greatest bargain in SET these days? Hi Charles, as you may have noticed he makes uses and sells is own R-Core output and power transformers, people and some hard core techs I know swear by them, far better than toriodal and better than EI core, is their responses. From what I Google... | |
What's the greatest bargain in SET these days? If your into great value for money, and not glitz factor. This guy in Japan makes some very good SE and PP tube gear, and has a large underground following. I've done some tests on his earlier 2a3 se and they were very good and are solid well made... | |
Preamp for Krell 750mcx Given the Kell has -Input Impedance 100 kohms-Input Sensitivity 3.71 VrmsHi BillAny preamp you like the sound of will run happily into this 100kohm loadUnfortunately passive pre are not on the list, while they would love the 100kohm input as well,... | |
Pass x250.8 vs Boulder 850 vs Spectral DMA250 I don't know the vintage of these and there are many many others to look at, so this is a bit of a guide only for you to do your own home work with. Here are just some that look to have bi-polar output transistors as they seem to come close to dou... | |
Pass x250.8 vs Boulder 850 vs Spectral DMA250 Maz65 look in your manual of the C-2500 under specs, it's 220ohm so no problem either.As you still mention the Pass and the Boulder these are both Mosfet output amps, while they both are very good amps, for your speakers they are not going to driv... | |
Pass x250.8 vs Boulder 850 vs Spectral DMA250 08-15-14: Maz65@I was asking for suggestion because coupling tube preamp and solid state amp could be very critical but I feel to follow this way, because I hear the potential of this solution.Maz65 (System | Threads | Answers | This Thread)Yes M... |
