Ralph - the Wagner you cite, what is your reference LP for that ?
best to you in the new year ?

16 ohm speakers: any amp sounds better with more resolution. speaker cables less critical.
Dear @charles1dad : Unfortunatelly wrong all your assumptions on me and the Agoners that I can see I know it them better than you and no not many of them have several first hand experiences listening LIVE MUSIC at near field position in a Music Hall just behind the Orchestra Director listening the Fantastique or 1812 or the like, of course that tehre are several Agoners way superior on that kind of experience than me. Or seated at 1m. from a drum set listening, at true real SPL, those Zildjan cimbals. I never talk or post something I'm not totally sure of it. I'm not insulting any one but facts are facts and only for your records I was a tube lover electronics for at least 10 years and heard almost any tubes from Jolida to the Audio Note ke-gon passing for Atmasphere, Allnic, Audio Research, Conrad Johnson, BAT, Cary, Wavac, VTL, Marantz, Luxman, etc, etc. Finally I learned. I'm sure you will too in the near future or maybe you already learned all what any music lover/audiophile must learns. If this is the case good for you. Anyway, appreciated but wrong. No, it's not because tubes vs SS, the overall issue is a lot more complex that only that. R. |
Hi Raul, I don’t question your experiences and the subsequent choices you’ve made as a result. You have extensive exposure to many fine tube components. I’ve extensive exposure to a variety of highly regarded transistor components. For your needs/objectives you have determined that solid state is the superior option. I ultimately was more persuaded by tubes. As dictated by our respective experiences we’ve chosen different paths to follow. That’s no problem at all. I respect your input on this forum. Charles |
tomic601 thanks for ’cool dude’, I think more like ’old dude’ many must think ’long winded’. I ordered everything for new DIY Speaker Cables COST: $136.44 incl tax & delivery ................................. CONNECTORS (spades and adapters at speaker’s back panel) .........................................................spades, pure copper 2 set screws 8 pcs CABLE: I ended up ordering a cat8 s/ftp (shielded, foiled twisted pairs) When you twist them you lose length, I need 12 ft straight x 2 = 24’ x 2 spkrs = 48lf straight, a roll of 50ft would be short. Speaker cables l/r should always be the same length (time of travel aligned, hah!). I chose this cable, ordered 10 m (33ft) red; 10m (33ft) black, each leg 16lf to make 12 ft: red/black twisted. https://www.ebay.com/itm/174307181712 22 awg, 8 solid (not stranded) OFC copper S/FTP construction = 13 awg This chart shows relative gauges, physical sizes, and resistance. https://www.rapidtables.com/calc/wire/wire-gauge-chart.html two basic choices cat gauges: largest 22 awg; smallest 26 awg 22 awg x 8 = 13 awg (+152% area above 26 26 awg x 8 = 17 awg (+152% resistance above 22 22 awg solid = less flexible is not an issue for me. .......................................... CONDUCTIVITY CHART https://www.bluesea.com/resources/108/Electrical_Conductivity_of_Materials silver is only a little more conductive than copper gold and aluminum are only a little less conductive than copper brass is a lot less conductive than copper COPPER TYPES (hard to verify true facts) often text says solid but diagram shows stranded; text says 23 awg, chart shows 26 awg, and seller’s answers are often not clear. https://www.thomasnet.com/articles/metals-metal-products/types-of-copper-wire/ ’Pure Copper’, (99.9% pure) often in text, with or without OFC is not in the above article, it is in this article, https://en.wikipedia.org/wiki/Oxygen-free_copper C11000 - also known as Electrolytic-Tough-Pitch (ETP). This is the most common copper. It is universal for electrical applications. ETP has a minimum conductivity rating of 100% IACS and is required to be 99.9% pure. It has 0.02% to 0.04% oxygen content (typical). ................................... L PADS will be disconnected, new + wire direct from crossover for both horns (one as a test first) ............................ WOOFERS, remove, check cones Picking these suckers up onto a low bench for the work is a job for two masked men. Recent MRI: I now have 4 herniated discs, one tear, pinched nerve. |
Dear @mijostyn : I use two Velodyne's and are along the main speakers but not firing to the seat position, here how are working: "" VELODYNE HGS-15: These two self powered subwoofers are in front of the main speakers and in side firing position. It crossover at 78Hz. I do some tweaks in the circuit for a better quality sound reproduction and I changed the internal wiring that connects the woofer to the internal amplifier ( 50-60cm ), the original is a very bad zip cord one that I changed with Kimber Kable KCAG that I soldered directly to the woofers and directly to the amplifiers: with no connectors in between. The power cord comes from Analysis Plus and is soldered directly to the inside subwoofer switch on/off with out no single connector kind ( at both sides/ends of the power cord ) and the IC cable is the Silver Oval by Analysis Plus too. I change too the internal electrical power wires that goes from the subwoofer switch on/off to the Subs amplifier, I'm using KCAG by Kimber Kable. Both subwoofers are " seated " over three Van Slike footers/isolators along with inverted Tip Toes ( position ) over these Van Slike isolators, so the subs are around 15-20cm. from the floor. Both subs have a dead-weight ( on top ) of 40kgs. NOTE: I'm not using the subwoofer internal crossover or an external electronic crossover to send the signal to the ADS L 2030. The crossover function ( high-pass. ) happens inside the two modified Levinson 20.6 mono-blocks at its input through a WIMA FKP1 cap and a single nude 0.001% Vishay 2575 resistor. In this way the signal from the preamp goes normally ( pure and clean ) to the 20.6s and to the loudspeaker with out any additional electronic stage or cables/connectors and the signal was taken directly from the Essential 3160 by the Velodynes. "" That's came from my virtual system details. Now, there are several advantages/benefits to the room/system quality performance levels when we use two good self powered subwoofers ( for stereo music and at one seat position that is where normally we all listen the system 2 subs are way enough if are good designs and are well integrated to the main speakers. ) but perhaps the more critical an important is that, it does not matters if planar or dynamic speakers as mine, the IMD goes way lower exactly where that kind of distortion makes more harm that's a woofer or planar element handling at the same time frequencies as low as 20hz and intothe 200hz-400hz and even higher frequencie range. This creates/develops really high IMD including the harmonics of the reproduced signal and this kind of distortions modulates for the bad all the quality sound that goes out side our beloved speakers and not only that but due to that high IMD the THD goes higher too. When the main speakers are liberated from the bass excursions of frequencies below 80-100hz we can hear it no matters what because the quality improvement is really huge. You can be sure that in the next example always things will goes as I stated: if you own ( example only. ) a pair of Wilson Maxx3 that you are handling it through the top CH or Dan'gostino amplifiers those speakers will performs really good but if if you adds a pair of self powered subs crossed at around 80hz the differences for the better will be higher that any MAXX3 owner can imagine it. This is the other critical and important advantages subs gaves us it does not matters if our passive speakers are full range and this advantage other that the one explained is that now those bass frequencies that are the foundation of MUSIC will be handled by a dedicated speaker designed in specific to mate/fullfil those bass frequencies needs along a dedicated amplifier too that makes the same. Those MAXX3 never can performs better with out those subs that with them integrated to. And believe me that difference is almost nigth and day. R. |
