| Poll: What's your KT150 bias set to per tube (ma?) Getting bias right on KT150 output tubes sure makes a difference. Wow. | |
| Poll: What's your KT150 bias set to per tube (ma?) @oldhvymec, "All the rage", hard to say. Fit for purpose, yes, most definitely. Took several steps to get to where I wanted it all to land. It took a lot to best my highly modified parallel strapped triode V12R amp, like yours. Part of this ... | |
| Poll: What's your KT150 bias set to per tube (ma?) Seems so. Just heard from my amp designer/builder. My KT150 amps sounded a little dry at 40ma per tube. 50ma showing real hope. Op manual shows 40-60 for my model. Asked if I could go up to 55 or 60ma. Designer shared "60ma is still well below the... | |
| Fritz Carrera BE stand mounts @jjss49, did not know you and Fritz are nearby, I'm in NorCal too. Some good feedback from a few colleagues on his speakers. A friend shared he felt Fritz intentionally voices them closer to some of the BBC/LS and Harbeths, which explains a lot of... | |
| Poll: What's your KT150 bias set to per tube (ma?) @oldhvymec - If you could limit the bass duty on the valves, I think you’d really be surprised. An unexpected added surprise was the lower register midrange and upper bass range that just came through biasing up on the KT150s. I usually run custom... | |
| Poll: What's your KT150 bias set to per tube (ma?) In my case I could go even higher on bias +5-10ma more, and remain in spec. First time I experimented with wider adjustment sweeps since amps were new. Seems I originally underestimated KT150s ability to sound more lush and "tubey". It is possible... | |
| Class D for a Tube Lover @audioguy85"The heat thing with class A is over blown in my opinion...Yes, they generate some heat, but not near enough to impact your comfort in the summer time."Not over blown for those who run larger high-bias / big transformer full Class-A amp... | |
| Soft, smooth organic SS integrated amps? @sbank "First Watt"Which ones are you recommending? The F1, F2, F6, F7, to F8 all have different circuits and different output transistors which sound and perform uniquely different. Some brighter and more detailed than others. | |
| Hoping for a recommendation for stereo amp around $1500 or less ($2k max) @brandini, Moving from your existing lightweight Onkyo receiver to a dedicated amplifier for your Ascend/RAAL speakers can be a worthy step up IF you choose well. It seems your Topping D90 offers (dual-active) preamp outputs (XLR & RCA), so yo... | |
| MHDT Orchid or Lampizator Amber 3? @quanghuy147 "I just got my own stock Orchid with WE 369 tube. The mid range from it is the best I have ever heard in years. Very detailed, smooth and musical. However, there are some areas that I wish it can improve: the dynamics, high and bass. ... | |
| Cary SLi80 amplifier - Effect of power tube exchange The sound will change a bit until those GL88s fully burn in. Give them some time. I enjoyed rolling several different new-reissue and vintage NOS 6992s and well matched 6SN7s in mine. That amp respond well to really good tubes. Keep in mind the ... | |
| Cary SLi80 amplifier - Effect of power tube exchange You're half way there. After the GL88s output tubes settle in, changing out the two stock 6922 Input Buffer Preamp and two 6SN7 Pre-Driver/Phase Inverter tubes makes a notable difference yet again on the SLI-80. Sure enjoyed mine even more afte... | |
| Theoretically better to connect my subwoofer from preamp out, or from outputs on my amps? +1 georgehifiAgree, use PreOuts. Last thing I'd want to do is to route a quality amplifier's speaker outputs and signal into yet another layer of cheap electronics, connectors, and crossover inside a subwoofer, and then on to another set of speak... | |
| Disappointment with Pass Labs - I'm looking for something else @opm, how open are you to demoing other preamplifiers before you mess with changing to other amps or speakers? I ask because there are countless references to folks changing out the XP12 for the X22/XP32 -and/or- good tube preamps with really pos... | |
| Disappointment with Pass Labs - I'm looking for something else @opm"it’s the cornwall III"+1 what @laaudionut said. Try a completely different preamplifier with your XA30.8. Also, I learned from Nelson directly he has a number of customers running really good tube preamplifiers with his amps too. Change the i... |
