| Bi-Amping Options B&W 801 Series 2 Yes, so sorry for your loss. May your memories of her remain vibrant and detailed for all of your days. My best advice with these speakers is to give them tubes and the best of those that you can; yes, this means to disregard the advice to give t... | |
| Bi-Amping Options B&W 801 Series 2 tomcarr is mistaken; your speakers do not dip to 3 Ohms; they have a minimum impedance of ~ 5.5 Ohms at ~ 10 KHz. This speaker has very benign impedance and phase angle curves which make for a very easy to drive speaker. Regrettably, I consider to... | |
| We should reject hard-to-drive speakers more often That does indeed read like a good bet Ralph. Don't know how to explain it; driving our North Creek crossovered B&W Matrix 801 S2 speakers (87dB sensitivity, nominal 6 Ohm with benign phase angles and amplitudes) with only our 100 watt monob... | |
| Tube amps - what 3 things… That's a very satisfying...and comprehensible!...description Ralph; thank you. | |
| Tube amps - what 3 things… Thanks very much for your input Ralph. The designer/builder of our custom amps told me that fixed bias provides more "snot" than cathode bias. He meant power by snot. I know you’ve stated in this thread that there is no power difference between th... | |
| Tube amps - what 3 things… Hidaleeho. Having computer troubles, so just seeing the status of this thread. Good exchange of info...good. Ralph, I'm sure that I'm wrong because I'm even more sure that you're right. Got some 8 Henry chokes on the power supplies of the amps... | |
| Tube amps - what 3 things… Excellent point Ralph! Properly executed ultralinear topology is stunningly impressive. When executed properly, it is another reason why fixed (manually adjustable) output tube bias is essential, in order that output can be optimized for ultrali... | |
| Tube amps - what 3 things… 1. (Big, read 1940s- 1950s NOS) Choke filtered power supply 2. Fixed (manually adjustable) output tube bias 3. 2 times maximum duty rated transformers (power and output) Bonus round: Point-to-point wiring | |
| What is your experience with amp power? Our custom tube monoblocks (75 lbs. with massive pi filtered power supply) put out about 100 watts each into our nominal 6 ohm 87dB NorthCreek crossovered B&W Matrix 801 Series 2 speakers. Our nearest neighbor’s house is about a 1/4 mile away.... | |
| What is your experience with amp power? bigkidz is correct. Do not concern yourself with amount of amplifier power, concern yourself with quality of amplifier power. | |
| B&W 802 d4 with Tube Amplifier Had been running (87dB) B&W Matrix 801 Series 2 with North Creek crossovers for 20 years with a Jon Soderberg modified Threshold Stasis 2 putting out about 225 watts per channel until replacing the Threshold with custom built Charlie Cocci Ult... | |
| Who Would You Spend A Day With - Pick Two petg60 and bdp24 | |
| The Forgotten Dodd Mr. Gary Dodd’s battery powered preamp is probably the quietest preamp of all time. His balanced power supply is probably the finest power supply of all time. | |
| Buying Equipment Based on Philosophy??? Yep. Philosophy of demonstrated excellent high voltage, low capacitance topology, point to point wiring, pi (choke) filtered power supply, handmade equipment built with the finest components; in other words, the finest possible. | |
| Treble and Tweeter trends over the past few decades Our Matrix 801 Series 2 with North Creek Crossovers have killed all speakers that have tried to challenge them. Unbeatable in every aspect. They’re in a very good room with phenomenal tube electronics. The Matrix 801 series 2 tweeter has been desc... |
