| Legacy Audio AERIS: RMAF/listening impressions? I was there and heard it. There was one big glaring problem that I couldn't get past. There was an obvious discontinuity between the tweeter and rest of the lower range. I believe it was first or second day of RMAF. Not sure if LA found a cure. | |
| Why do audiophiles shun feedback in amplifiers? Learsfool, "neutral", in almost all cases, is a subjective audiophile term. IMO, only people truly qualified to use this term are recording engineers who have the capability to compare their recordings with the live performance that was recorded i... | |
| Why do audiophiles shun feedback in amplifiers? Charles1Dad, go to these links:http://www.hans-egebo.dk/Tutorial/tubes.htm Go to "Tubes become active" section.http://www.diyaudio.com/forums/tubes-valves/178688-triode-plate-resistance-internal-negative-feedback.html | |
| Why do audiophiles shun feedback in amplifiers? Learsfool, I know "tight" is not a term most musicians use. But we audiophiles (and closet musician on the side such as myself) have our own set of terminology that will befuddle most musicians. We use many different terms to describe the similar,... | |
| Why do audiophiles shun feedback in amplifiers? Kijanki, thanks for pointing that out on the Stereophile article. One famous amplifier designer told me there is no such thing as totally zero negative feedback. Even the tubes themselves can have built in feedback. | |
| Why do audiophiles shun feedback in amplifiers? Learsfool, this is all semantics. I have been playing classical guitar since high school, and have dabbled in piano and sax. I have attended concerts at some of the finest halls in the country (Symphony Hall in Boston, etc) and listen to live unam... | |
| Why do audiophiles shun feedback in amplifiers? Good point. | |
| Why do audiophiles shun feedback in amplifiers? Ah got it, Charles1dad. May be one day, if I have the right speaker, I'll get a DHT amp. But I'm not sure if I can deal with the heat. My OTL amp raised the temp of my listening room by 15 degrees F easily in the summer. I've owned KT88/6550/KT120... | |
| Why do audiophiles shun feedback in amplifiers? Thanks Kijanki for the link. | |
| Why do audiophiles shun feedback in amplifiers? I thought KT88s are beam tetrodes, not pentodes?I do like the sound of DHT amps without feedback in the right system. They have a certain magic to the sound that I think is missing in tetrode or pentode amps with feedback. IMO, DHTs are more expre... | |
| Why do audiophiles shun feedback in amplifiers? Ralph I think we're confusing semantics regarding 'tight' bass. To me, a KT88 amp with feedback has more natural bass than most SET amp with no feedback or for that matter an OTL amp with miss matched speakers. | |
| Why do audiophiles shun feedback in amplifiers? Mapman, I agree with you. The ears have the final say. That is why I posted. IME, negative feedback is beneficial. | |
| Why do audiophiles shun feedback in amplifiers? Getting back to my original point...here's a thought experiment. Let's say you design a tube amp with different levels of negative feedback, let's say in increments of 3 dB from 0 to 30 dB. Assuming you have a good speaker/amp match, what you you ... | |
| Why do audiophiles shun feedback in amplifiers? Ralph, by "tightness" I'm referencing real acoustic bass instruments such as kick drum or stand up bass. Therefore, it is not an system artifact. | |
| Why do audiophiles shun feedback in amplifiers? Thanks everyone for the informative responses. In regards, to speaker/amp pairing, I have three sets of speakers, two pairs are dynamic and one pair electrostatic. In all three of these, overall I liked feedback over none. As for DHT amp using no ... |
