    1-2k to partner PS Audio Sprout100

    PMC is outside my budget I'm afraid. System needs to be mobile so no floorstanders. Yes, speakers are very personal. Previous speakers I have liked a lot in owning or audition were: Proac Studio 100 MA Silver 5 (owned) Acoustic Research M1 holographic (owned) Entry to mid level Magnepans Original Legend Kurre Audio sphere Sphere2 (current) Krix Superbrix Entry to 20k current range Martin Logan electrostatics Prefer less bass/fast speaker to more bass but slow. Value PRaT and hate harsh top end...
  2. Looking for recommendations of speakers to partner a PS Audio Sprout 100. Thinking Sonus Faber Venere 1.5, small Dynaudio (Emit M10 or M20), the smallest Monitor Audio Silver... Thoughts or suggestions anyone?

    Mobile System: Sprout100 plus what?

    Keen to take a feed off the Garrard, for sure. Want to get the Sprout100/speaker combo sorted first.

    Mobile System: Sprout100 plus what?

    Outside the budget I'm afraid. Really wanting speaker advice.
  5. In a quandary folks. My main system is a pair of single driver Audiospheres powered by a PP EL84 amp. Main source is a Garrard 401 with alloy bodied DL 103r feeding a MF VLPS and VPSU. In moving house, we want music on the verandah, out the back, when cooking, as background when dining... I was contemplating ceiling speakers in zones, but even a basic multi zone setup will be mega dollars. Out of the blue, my wife suggested a mobile system on a trolley. So, I contemplate the following: PS Audio Sprout 100 (100w into 4 ohms) with a macbook pro as source (where all our iTunes is) and a good pair of bookshelf speakers in the 1-2k range. Early shortlist options are Dynaudio Emit 10 or 20, or Sonus Faber Venere 1.5. We listen to everything. 80s and 90s dance, jazz, female vocal, blues, rock, metal, pop etc Any thoughts?

    Tests for system "resolution"

    A great test for system "speed" is Hotel California by the Eagles. There is a dropout in the master tape. On a fast responding system, just after the line "bring your alibis" you should hear the studio soundscape momentarily vanish completely. It's actually quite disconcerting to hear...

    Condescending is one thing... I'm happy to wait until I've heard the Emperor before I make a judgement on the clothing...

    Zaphod, triodes don't "employ" degenerative feedback... They "employ" the attraction of electrons to positively charged surfaces and the repulsion of electrons from negatively charged surfaces... Inherent linearity isn't the same as a circuit workaround to combat an inherently nonlinear device.

    Think you're meaning Musical Fidelity A1, not the Sugden A21a... Don't recall a claim that it was SE.

    I'll deal with the last, first. I'm not aware of any solid-state bjt that operates linearly without feedback applied. (Something triodes have been easily able to do for 70+ years). Never claimed a 20-20k response. Given that precious little beyond Duntech Sovereigns even try to claim a response like this, to criticise single driver speakers for not doing what 99% of other commercial speakers can't do is a long bow to draw... I'll take my fast responding light cones in concrete enclosures and a 50 - 18k response at 94dB/W happily. Less "time smear" than all the timber cabinet multi way speakers I've ever heard. Sorry to disagree (or not go for the 20-20k straw man).

    This is all getting miles away from the OP... I guess my take is that music happens in the time domain. Logically, any correction system like negative feedback *must* at its best, trail the original signal by at least one cycle to have a corrective effect. That being the case, short term impulses which are not a sine wave are being "corrected for" even if they are not actually an error in the amplifier behavior. Effectively we are deliberately introducing time domain errors into any non steady state signal. I can't see how that can be an ideal approach to music reproduction. Better to not make the errors that need correcting in the first place... For me, the smallest number of amplifier stages that can do the job well, operated in a linear manner which does not require correction, and feeding a speaker system that responds quickly and efficiently to the signal they give is a more desirable approach. With that in mind, I favour simple triode circuits without feedback and with high sensitivity single driver speakers that don't time smear. I'd like to replace my zero feedback triode connected PP EL84 amp with a PSE 2a3 amp at some point, but dollars and bench time don't currently permit... I like the concept of not trying to cross over the zero magnetism zone of a transformer core and just dancing in the micro signals plus and minus around a pre set quiescent current (which is why, for me, parafeed and similar approaches are also missing the point). Guess the proof will be in the pudding...

    Arguably, this applies to any Class A or any tube amp... I guess this means we aren't all chasing convenient, cheap, cool running, efficient, light weight or high powered...
