impedance match of preamp and main amp. Cturnem, sounds like you want to keep your Bat preamp, and that Mac looks to be a nice amp, if your keen on owning it. Your Bat preamp is a low 410ohms output impedance at most frequencies and into the Mac it has a good ratio of 1.24, the problem ... | |
Active vs Passive Pre amps David12: The passive seemed more neutral and detailed, the ARC a little rich and lush. I know you are supposed to lose dynamics with a passive pre.Hi David, first off your system as you have found just by listening, is a perfect impedance match fo... | |
Lightspeed Attenuator - Best Preamp Ever? Very good Lacee, you couldn't ask for any better, enjoy.The Lightspeed's volume action/structure is logarithmic, and after 1 o'clock it rises exponentially in level till full. So as you can see at 1 o'clock you are at around only 30% to 40% of ful... | |
Lightspeed Attenuator - Best Preamp Ever? That's great to hear Lacee, echoing many of my customers are reporting back to me and say that with the Lightspeed Attenuator as the preamp it's the best they have ever heard their vinyl/phono sound.I did a bit of searching and found your Steelhea... | |
impedance match of preamp and main amp. Al's right Cturnem.But a simple solution for you if you want to go this way and use the Mc602, is to get a technician to change the coupling cap in the output of the Vk 51se and replace it with one of the same quality but say 4 x larger in uF (mic... | |
Wanting to simplify my system ...... Hi Chris, the MkI Sasha's they are a pig to drive and need current, and the Gryphon Diablo Integrated looks to me as though it will do that job much better that your AR Ref-150 can, this is maybe why you liked it so much. As the Gryphon can do 250... | |
What Exactly Does "Burn In" do for Electronics? "ZD cited just above." Is again not a technical explaination. Could conscrewed as getting used to the sound so you don't take it back for refund.As for trimpots Peter (Csontos), yes if they are left in one position for a while they do tend to loos... | |
What Exactly Does "Burn In" do for Electronics? So it seems like we are in agreement, that to us "break in" for better or worse can occur with the mechanical devices such as speakers drivers, cartridges, and tubes, as you also said.And you and I will not commit without skirting around the edges... | |
What Exactly Does "Burn In" do for Electronics? So Al, by disagreeing respectfully, are you saying that you believe that "breakin phenomena" does exist?? Or just to my assumptions that there should be a measurable difference in component specification? And if so, in which do you believe the "br... | |
What Exactly Does "Burn In" do for Electronics? Interconnects can sometimes alter things, all are different in construction, and parameters such as impedance, capacitance and inductance, of the cable can have filtering effects when used on high output impedance devices, such tube preamps and pa... | |
What Exactly Does "Burn In" do for Electronics? 06-22-14: CsontosIt makes no sense that the expectation is for parts to fall out of spec in order to fall into a desired lower cumulative level of performance. Ridiculous. And how would this be accomplished within a reasonable time frame? By using... | |
What Exactly Does "Burn In" do for Electronics? 06-22-14: Zd542"Ok lets say things do change after "burn in", how does any designer compensate for this, in his calibrations, measurements, tests and design????"They compensate for this by breaking the prototypes in before they listen and measure.... | |
What Exactly Does "Burn In" do for Electronics? "Burn in" believers imply that something will change for the better after a period of time. The only way this can happen is if the characteristics of the components change. All good equipment is measured, tested, calibrated and designed to perform... | |
Have thiel 3.6's. Will mcintosh ma6600 work? I use to have the 3.6's great speaker but hard to drive. They can be in your face a little through the mids and highs, and they need a amp with good tight controled bass.They do remain mostly under 3ohms, so an amp with good current is a must. Ste... | |
What Exactly Does "Burn In" do for Electronics? 06-18-14: BifwynneBtw, maybe not so crazy. I understand that low temp cryo "cooking" of metallic parts like gun barrels, engine parts and so forth changes the crystalline structure. The result is stronger and longer lasting parts, so the cryo pro... |
