Fuses that matter. r u sure	691
Amplifiers:A Keeper for Life. Do you know of one ? phiser labs	487
Bass leaves after amp warms up? I guess that transistors don't have enough heat sink and go hotter than supposed to be in normal operational state. The noiseless fan can probably rectify your situation	401
Ok this will be a good thread. in this case one-D thinking cannot be precise since saying that speakers or amp are the most important components is just like measuring the length of a shadow not knowing the . . .	220
Modern Linestages I bet that overall circuit components would not exceed $1000 even on these preamps. It's obvious that from circuit components net worth of $1000 you can have world class . . .	156
Power output of tube amps compared to solid states tubes have high output impedance so they need transformer to convert its output voltage into current to drive nowdays speakers. hence the power of tube amps become less 'visible' . . .	154
high power tube amps vs ss It's important experience, but smarter to switch back from tubes	126
Lifespan of a quality solid state amplifier? Agree. To build powerful SS amp that would last for 40 years is challenge. Bryston deserves respect	94
Equipment Break-in: Fact or Fiction FACT: If equipment sounds like $HIT out from the box it will never sound like HONEY even after recommended 300 or N00 hours. Usually if you upgrade a component or a few it should . . .	92
McIntosh - is it that great? Another vote for 402. I've actually heard 452 that is slightly more powerful, but what I heard isn't solid state or tube performance. It's just a Mac that is capable to show how it. . .	91
How do I keep my cats off my amplifier? drow a scary dog on the top of your amp. if you can't yourself, then hire an artist	88

Pre-amp suggestions for Thiel 2.4/Pass Labs XA30.5 I think you'll get better and cheaper results if you'll just use CAP151 which will make much more sense than your current Pass that underpowers your speakers. You can order a phono. . .	83
Break in period The bottom line is if you like sound out of box than you don't need to worry about break-in	83
Class D amps There are class T(TriPath) that I personally prefer over the class D. Being a studio tech hobbyist, got used to clinical and clean sound to evaluate a recording quality. Learned to. . .	82

Upgrading wall outlets Countingbackwards, well put except that the outlet isn't a filter at all	76
How big of a difference do amps make? Contrary to Schubert, I drive my Aerial 10T with Sunfire SRA(bought NOS $450). Feels like I need a-bit more power of let's say Sunfire 300(used $700) and I'm sure that it will . . .	75
Is solid state on the brink of extinction? Slappy, I guess you're just pretending not knowing about digital amps. Class "D" is pulse operated amplifier. Pulse generator with pulse freequency F is usually placed before the . . .	75
Switched From Tubes To SS???Glad You Did??? Had tubed amplification with VTL MB100, Than had a biamp setup, than got rid of VTL MB100. The only tubes I have is in my guitar amp	74
The Best Amplifier Ever ? I stand for ORPHEUS headphone system amp with ear-speakers that no amp/speaker combo can beat under any circuimstances	74
Anyone have honest opinion of Jolida amps? If you replace the original Chinese tubes with at least Russian ones you'll have a descent amp for the money spent. Imagine that you're buying a tube amp without the tubes -- that'. . .	72
Can HI FI components really make music? No way dude! Music is being made by composers and/or musicians or combination of both listed above	72
Does you wife touch your system? digital OK, but not analogue	71
Best preamp is no preamp: always true? A meaning of a PREAMP(POWER-AMP) is relatively new v.s. previouse meaning of just an AMPLIFIER. Whatever we take as PREAMP is actually the part of an AMPLIFIER. So depending on a . . .	70
Best Digital Amps One side is a great potential to get more power due to the high efficiency but in my listening experience I only heard the lack of one despite even of power ratings. I also heard . . .	69

I am openning a shop. What equipment should I sell Vacume cleaners	67
Solid state amp ultimate stop... I'd stay for Pass X250 or Plinius SA250. Both of these products are realy ultimate on all audio qualities you can only think of, but certainly costly. If money's no option, I'd . . .	67
High-end amplifier clarification? Non-high-ends are the following: No tubes. Class D or T. Less than 90lB. Has cooling fan. Less than $5k new. Does not have detachable powercord(limited upgrade possibilities). . . .	66
Progressive Rock Rock is not high-end-ish music. It's more complicated to record well and therefore it often doesn't sound as good as Jazz or Classical. Revdog, prog bands even with big contracts . . .	64
Why do some audiophiles beat up McIntosh? Agreed. Cadillacs and pain in behind are synonyms. Coca Cola is good to get rid of corrosion, but not digestion. Most Harleys are way overpriced and poor performers indeed. These . . .	63
Preamps waste of money? Your case is one of a line of particular cases where you have sufficient input sensitivity for the rated output power and sufficient high input impedance. In many other cases . . .	61
Is it possible to get Hi-end sound ?? ipod classic; behringer headphone amp; sennheiser px200. <$100	58

Best Integrated amp for under 4k Plinius 8200MK2. Not sure what your speakers but it bests with heavy loads such as Thiel or JM-lab. Used one is sold for less than $2k and will give you more room for speakers or . . .	45
Does the volume control effect sound quality? YES a lot and so is aging of such. Replacement of one in 15 years+ may drammatically improve the sound	44
Why my system has detail but no body & warm vocal? don't know about speakers, but replacing your amplifier might do just a right trick. change it to Creek integrated or the best will be Bryston 3b-st paired with passive preamp . . .	44

The Fastest most musical amp Plinius SA100 speaks for itself. It doesn't need a super-preamp and you can mate it with McCormack TLC1 in passive mode or Adcom GFP750. It bests with heavy speakers such as JMLab. . .	43

Quietest amplifier you have ever owned. so what's the point there? i believe that 120db s/n or any doesn't mean that it can play music. i'm ok with my vtls that are arround 95dB s/n(well, i probably have to measure it . . .	37
Tell me if i got it wrong.. Wrong, The digital signal circuitry can be done with tubes too, but very ineficient since they aren't fast enough on higher freequencies. Transistors as well as tubes can produce. . .	37
Pre amp for Pass Labs XA30.5 – Tube or SS far not too many tube amps will be good with your amp and definitely not ARC of any model you can try BAT VK51 or VK31SE, but using solid state preamp is encouraged. I'd choose . . .	36
