| Desire to try tubes Hi Veerossi,I also think that the Line Magnetic 805ia is an excellent recommendation. One minor correction, this integrated amplifier uses 300bs as driver tubes. The output tubes are the DHT 805 producing 48 watts per channel. That’s a lot of SET... | |
| Cube Audio Nenuphar Single Driver Speaker (10 inch) TQWT Enclosure Keith,I don’t believe that anyone is going overboard in regard to the damping factor (DF) variable . The Nenuphar manufacturer himself has clearly and often discussed the inherent damping of the unique driver. He has explicitly stated the driver i... | |
| Cube Audio Nenuphar Single Driver Speaker (10 inch) TQWT Enclosure Agree that if the power amplifier was encountering a speaker impedance of less than 1 ohm (0,89 ohm) this is an enormous challenge for 'any' amplifier to manage. In fact most amplifiers would be incapatible of delivering the vast amount of curren... | |
| Desire to try tubes Hi facten,Thank you for your kind comment. The OP admits he is new to this endeavor. I just wanted to assure him that with reading, time and patience he'll realize that 5,000.00 can go pretty far if he's careful and learns more about the high en... | |
| Cube Audio Nenuphar Single Driver Speaker (10 inch) TQWT Enclosure Yes I wondered the same in terms of the exponential (10x) change in the DF value with just a simple resistor addition. I'm surprised that its of such magnitude. But in practical terms the sound quality did improve. Charles | |
| Desire to try tubes Billeauxbrew, You have received some very good recommendations.You have several factors in your favor that can help you fulfill your stated goal. 1Your speakers are both high sensitivity and are known to be easy to drive. You do not require much p... | |
| Cube Audio Nenuphar Single Driver Speaker (10 inch) TQWT Enclosure Hi debjit_g,DF=Speaker impedance (In ohms) ÷amplifier output impedance. So to lower the DF either the amp output impedance must increase (Denominator) or the nominal speaker impedance is decreased (Numerator). Unless there's something I'm missing.... | |
| Cube Audio Nenuphar Single Driver Speaker (10 inch) TQWT Enclosure Stephen,Congratulations! It’s interesting that this simple step reduces the DF by a factor of 10 and improves what was already a very high level of sound quality. This was an excellent suggestion from the knowledgeable Vinnie Rossi. It certainly d... | |
| Jadis JA30 Mk2, how great??? No doubt each individual designer or manufacturer has their own ideas and philosophy regarding the best approach to produce good sound quality. I certainty haven't heard every ARC or Jadis amplifier but based on my limited sampling I'm more draw t... | |
| Jadis JA30 Mk2, how great??? Samhvcc, You express considerable interest in the Jadis SE 300b mono blocks. Although this is a PSET (Parallel single ended triode) topology it is rated at a relatively low 10 watts per channel. Typically a 300b PSET is rated at 16 to 20 watts per... | |
| Cube Audio Nenuphar Single Driver Speaker (10 inch) TQWT Enclosure debjit_g Tektron offers quite a range. Besides 2A3 and 300b they have a 211 tube integrated amplifier. This is pretty unique. Of course they have a plethora of non DHT pentode type el 34, KT 88,KT 150,6550 models. etc.Charles | |
| Most desirable vacuum tubes for SET amps The el 34 is a good sounding tube but is a pentode and not a (Innately) triode (Although it can be re-wired to triode).It is 'indirectedly' heated as opposed to 'directly' heated triode (DHT).I believe that the OP was referencing specifically to... | |
| Jadis JA30 Mk2, how great??? It makes perfect sense that the Big Esoteric mono blocks would be a very successful pairing driving the Sony SS AR1 speakers. High current capable transistor amplifiers are what the Sonys were meant for. The Grandioso's output power doubles as the... | |
| Cube Audio Nenuphar Single Driver Speaker (10 inch) TQWT Enclosure debjit_g, Here's another possibility. The Canadian company Coincident has an integrated amplifier named the Dynamo. It is available in two versions, el 34 or 300b (A bit more expensive but I think excellent for the Nenuphar). Both of these are si... | |
| Cube Audio Nenuphar Single Driver Speaker (10 inch) TQWT Enclosure debjit_g, Line Magnetic is an excellent suggestion for a very high quality tube (Particularly SET as well as push pull) integrated amplifiers. I’d also recommend that you consider the Italian Tektron brand as well. They offer quite a large stable ... |
