| Impedance match Matching concerns for all passive preamps is even more critical, if one doesn’t get at least a 1:6 ratio or higher from source to input and from output to amp then the wrong conclusions will be drawn about passives and the way they sound. If done ... | |
| DENAFRIPS DAC ---- Owner Impressions, Feedback, General Discussion, Questions and more.... Winner for: "High-value true-balanced pre /power combo" Very weak on giving any specs for the amp, even on the Denafrips website. Doesn’t instill much confidence .No input impedanceNo output impedance or damping factorNo 4ohm wattage ability or 2... | |
| Bench testing amp Most EE techs that build their own amp/s or even good ones that repair, should be able to help you out with most if not all bench test measurements.I don’t know where they are, but these guys have one of the most advanced detailed bench testing se... | |
| Looking for suggestions on best small footprint speaker under $4K miamiangler Looking for suggestions on best small footprint speaker under $4K They can be got for around that price now used, if your lucky and a good haggler, and that’s a pair of Sonus Faber Extrema’s old, (new will cost you a kidney), best s... | |
| Impedance match Yes when the output impedance to input impedance (O/I) ratio got down to 1:5 then a couple listeners said they could hear the dynamics may have been getting a little effected, but they said it was very small and don't think they could of blind A/... | |
| Audio Research Ref 5 SE ting noise you were spot on George! A slight flick pretty much reproduced the issue. You could try these also for the others, far cheaper than audiofool ones. Just don’t make them too tight, I have seen it kink the glass over time, and they must be the high... | |
| Impedance match noble100 I always read and was taught by members here that the guideline was at least 10x but will work well together with anything greater, too. Identical match is definitely not correct. With source to pre, pre to amp.Once you have a "Outp... | |
| Schiit Freya Thump or pop sound Turn on sequence = source, pre-amp, power amp. Turn off sequence = power amp, pre-amp, source. +1 This should be is written in stone in the audiophile bible Cheers George | |
| GaN-based Class D power amps tweak1 George, wasn’t it you who told me when I had the Hattor XLR passive pre George, wasn’t it you who told me when I had the Hattor XLR passive pre that it was a impedance mismatch with both my Emerald Physics, then later with my Audio Alchemy... | |
| GaN-based Class D power amps We are testing different input impedance values for the best result in all situations. .Once the final number is settled on I’ll let you know.. Testing??? there's nothing to test, once you have a "Output to Input" impedance ratio of 1:10 or mor... | |
| GaN-based Class D power amps Not when you knowingly prop it up in-between the speakers like the "great glitz audio god" and ruin any great stereo image and depth you may have had, then your "what you said"Cheers George | |
| GaN-based Class D power amps You must absolutely hate fine art. I buy audio equipment first and foremost for it’s sound, second comes price, last is looks. I’m not one of these that sets up his "glitzy chassis" multi $k equipment in between the speakers on just as "glitzy" r... | |
| GaN-based Class D power amps Enjoy the board then. I’ve got higher standards. Please list all the item no.’s in the BOM list I posted that you or someone else would improve on, and with what and why?https://www.scribd.com/document/398286093/EPC9106BOM-1Cheers George | |
| GaN-based Class D power amps $1,400 Digikey EPC evaluation board, keep in mind what you are paying for: PCB’s stuffed with mostly non-premium parts Really!!!!! I see nothing but premium parts! And I wouldn't expect anything else from a companies eval board.https://www.scrib... | |
| GaN-based Class D power amps You can do that, or just get a hifi shop to demo the Technics SU-G30 for you, being only 50W on yours or some low wattage efficient speakers. I'll wait till I can pickup a pair of GaN monoblocks complete with Chinese Sangway type boards in them fo... |
