| Pass....Accuphase....or...... @southofdallas I have A48 and P4500.. A48 is better for mid <50W peak power, very smooth/warm, P4500 is excellent for higher volume sounds <150W, rock etc.. P4500 is basically not different from A48 below 5W power. | |
| Mullard EL34 that sounds best I would recommend JJ power tubes https://www.jj-electronic.com/en/power-tubes pro: very stable over long run time Luxman Japan uses those for all noble tube amp designs | |
| Pass....Accuphase....or...... +++++ Accuphase A48 great if not greatest <50W/ch SS A class amp! advantage: no maintenance needed for few decades! +++++ Luxman MQ-88uC lil less peak power headroom than A48, amazing dynamic range, very low noise floor for tubes, very gentle... | |
| Question about high current amps versus "not high current amps" @atmasphere correct! :-) Testing amp “effective” current range is not trivia, and it is beyond what is discussed in AG! my post was a simplest debug approach to check for major amp-spkr issues, before starting to randomly change components! | |
| Would I be wasting my money to get a turntable? belt driven not sync TTs with +/-1% speed spec don’t work for me.. voice/guitar/etc out of tune! | |
| Question about high current amps versus "not high current amps" @panzrwagn +1 simplest test of amp current handling adequacy is to tap low frequency. driver membrane and checking voltage waveform at speaker terminals with the scope.. if voltage amplitude p-p observed is more than 10mV, then need to check speak... | |

| Thickest Power cord with Power distributor? @miracle1980 power quality depends on (too) many things.. first I would recommend to test outlet point by plugging vacuum and lamp into it, and check if light dims when vacuum motor turned ON.. if you see no “visible” IR voltage drop, then few hun... | |
| Speaker Jumper/Link Cables - Best Ones? Nordost Valhalla, Tara Labs Omega Evolution OR.. @mylogic "Seriously can a few inches of jumper cable really make a difference?" few inches of cable have resistance in 1….3 mOhms range, which is irrelevant. bigger problem is speaker itself, which uses sometimes bad posts (gold / other plating ... | |
| Question about high current amps versus "not high current amps" @dlevi67 +1 amp does deliver current to speaker-load, AND also dampens / controls current from speaker (inductors and capacitors in passive crossover, inertia generated current by drivers), thus higher current than just driving resistive load out... | |
| Why Do ~You~ Still Play CDs? "Why Do ~You~ Still Play CDs?" ..cause I like to listen to my CD collection! CDs on my Esoteric K-03XD sound awesome! | |
| Looking for a Replacement for AT VM740ML Cartridge @skiznfliz get MM cart from Audio Technica house AT-150MLX ! If you want the best, try to get NOS / good from ML150..180 series.. my AT-ML180 kills 1500$ MC carts, while running at half track force, 1gf MM vs 2gf for MC! | |
| 75 Ohm BNC cable "It includes connections inside of electronics on both ends, so it would be safe to go with less than 12 inches to avoid reflections. “ Circuits, Tx/Rx, I designed, match driver and receiver impedances to cable, thus no reflections on both ends,... | |
| Let's talk about Silver... @richardbrand "So about 5.7% better conductivity for silver than for copper” - yep, just make Cu cable of the same gauge 6% shorter, or increase gauge by 6% and you are better than w/ silver! dielectric, which directly impact prop delay, used fo... | |
| 75 Ohm BNC cable why do you need to cut original cable? additional 15inch cable will not hurt your clock or other digital signal much.. if you are DIY person, there are very good cables to terminate by yourself w/ BNC... |
