| What Class D amps will drive a 2 ohm load Whatever Ralph.Seems like this could be the module your using, as you've turned up the force shields a notch higher on this one, if so just go with the buffer by-pass switch. | |
| What Class D amps will drive a 2 ohm load Our preamps can drive such low input impedances-Of course it can, how did I know that was coming, stick with tubes, your good at it, and built your rep on them. The fact is this amp without buffer it has around 15db of gain around the same as the ... | |
| What Class D amps will drive a 2 ohm load Custom buffer adds gain and increases impedance to 47k ohms. There’s no need for it in many cases, as sources and preamp have enough gain these days. It’s just "another opamp in the signal path" that’s not needed in many cases if the input was hi... | |
| What Class D amps will drive a 2 ohm load Purifi 1ET400A has no buffer, so it is expected to a manufacturer to add a custom buffer, and add more gain as needed. It also has a disappointedly low 2.2k input impedance, so the use of most capacitor coupled (unless >10uf) preamps, tubes, o... | |
| Spectron Audio Out Of Business? do you know someone there George? No sorry, but bjt a 25 poster has the amps and says he knows a bit about them, maybe he knows something about the company.https://forum.audiogon.com/posts/1797196Cheers George | |
| KEF 104/2 tweeters I wouldn't de-value the 104/2,s with a different tweeter, the Kef T33 was a great tweeter when new they also used it in the 107/2, just get some bad raps these days when old and crusty and half seized with dried up ferrofluid. Also the T33 was de... | |
| What Class D amps will drive a 2 ohm load I did see this:Output Power, Short Term8ohm, 1% distortion = 227 watts4ohm, 1% distortion = 450 watts2ohm, 1% distortion = 450 watts with a footnote stating "Power is limited by overcurrent protection system (OCP) and highly dependent on thermal ... | |
| Spectron Audio Out Of Business? I wonder what has become Spectron's inventory of spare parts, tools, testing equipment etc? Their site's still up and working.http://www.spectronaudio.com/contact.htm Cheers George | |
| KEF 104/2 tweeters Those tweeter sound good when overhauled. Dismantle them gently kneed out the dent from behind, clean the magnet gap and voice coil of all old gunked up ferrofluid , and fill the gap with new ferrofluid (ebay), don’t over fill as the voice coil an... | |
| How could 100 Watt class a has more head room than a 300 Watt amp Class AB From the Stereophile XA60 review it'll do 130 watts into 8 ohms and keep going up as the impedance is lowered. 130W into 8 ohms 210W into 4 ohms 330W into 2 ohmsIt's no wattage doubler as you can see from the Stereophile tests, but it at least... | |
| What Class D amps will drive a 2 ohm load I would (and actually did) choose to buy amplifier B. Good quality sound? into hard speaker loads it’s all about current.If you wanted the "best sound (not volume)" into speakers that dip to below 2ohm for most of the bass, then you chose poorly,... | |
| Which Class D Amplifier? PS Audio, Ghent, Nord, Merrill or other??? I am scheduled to get a prototype soon. Could they possibly be "THAT' much better? You are "really blessed" to get the usually closely guarded prototype to evaluate from a manufacturer without being affiliated to them in any way. If it's... | |
| Naim Audio system owners - What speakers are you using with Naim? Back in the old days I believe Linn/Naim Ivor Tifenbrun and Julian Veriker were in cahoots. If you had Linn Isobaric speakers (an over damped design Q.3) you used the Naim 250 that had poor damping factor 8 for memory, both compliment each other t... | |
| What Class D amps will drive a 2 ohm load the Bryston 14BSST would go into protection mode from overheating due to the impedance. With these sorts of speakers like the CS5 ect it’s no wonder, these tested figures show it was definitely no current master into low impedances 8ohm load 690... | |
| Good CDTransport (player) without DAC? mahler123763 posts09-01-2019 10:51pmCambridge Audio transport usually gets recommended Cambridge CXC transport is a cracker for just $600, common CD laser not DVD, that cheap to get, should it’s ever needed, and it’s got one of the lowest jitter ... |
