Review: Counterpoint SA-1000 Tube preamp I sold my SA5000 (tried both with and without follower jumpers) even before the Plitron mod and the final regulator mod to this monster PAS3.The 2 preamps were compared at 3 different places (mine and 2 friends') and there is no comparison. The SA... | |
Cary SLP-98 v. Manley Shrimp The SLP98 I owned briefly did not even sound remotely as good as a stock Ming Da MC-2A3. The Cary has a very artificial mid high which works well for certain kinds of music. Bass is worse than the Ming Da despite my attempts to change out the caps... | |
Review: Ming Da MC-2A3 Tube preamp 4 things that made the most difference with my unit are:1. output caps: replace them with Mundorf Silver oil, greatly increased transparency.2. minor mod to the circuit to follow the schematic. Cleans up the sound a lot. Funny midrange harmonic an... | |
6SN7 based Pre-Amplifier Found 2 major design flaws of the Ming Da:1. Filament power supply in series, 2 supplies, one shared between 2 6SN7 and the other among 3 6922, non regulated.Be prepared for it to sound good one day and bad on another.2. Grid resistor from 6SN7 st... | |
6SN7 based Pre-Amplifier Tried the stubby Syl chrome top in the regulator and RCA smoke for the input/gain stage 6SN7s. Sounds OK but top end is colored (there's a frequency in the mid high thats recessed and a little above that its pronounced).I think tube-rolling among ... | |
6SN7 based Pre-Amplifier Regarding the Ming Da MC-2A3.Am already using RCA2A3 for rectifiers, GE british EL34 for regulators,and swapping from among my RCA smoke glass, CBS, stubby Sylvania chrome tops, and KenRads.Each combo yields a different flavor (color) and I am hav... | |
6SN7 based Pre-Amplifier The Consonance sure looks enticing, the tube config also looks right.(Love them 6SN7s)The concern is whether Consonance can build a 6SN7 preampthats quiet and not bloom-and-gloom bloated.It would be great if the inside is point to point wiring(pot... | |
Best Preamp for under $1750.00 Where can you find a Consonance Cyber 222 Mk II for $1500?Does anyone know how the 6SN7s are wired (SRPP? parallel?)Thanks.Got a Ming Da MC2A3 myself and it seems to be a pretty good deal.Bass is a bit loose though. | |
6SN7 based Pre-Amplifier I wrote a mini-review on the CA906 and submitted it to www.high-endaudio.com. Just bit the bullet on a Ming Da MC-2A3.Not nearly the same class as the CA906 in terms of build(I have NEVER seen layout and soldering as good as Canary products), qual... | |
6SN7 based Pre-Amplifier I had the opportunity to listen to a Canary CA906 (2 6sn7s per channel with extensive tube rectification and regulation) in my system with both the VAC Phis and NP220s.This is probably the best production preamp I have every heard.Details later. | |
6SN7 based Pre-Amplifier there seems to be a 6sn7 variant of the aikido I think is worth looking into. | |
6SN7 based Pre-Amplifier Polk432 are you hinting that the MC-2A3 is a fraudulent listing? Or are you referring to an SLP98P? Seller of the formet seems to be some shipping liquidator. | |
Avalon Eidolon and Krell, good match or not? I do believe Audiofeil has listened to more setups than Mr. Dave_b. Rather than just a hobbyist, Audiofeil is a pro and has been in the business for years.Since live sound is impossible to recreate fully at home,I would opt for the more enjoyable ... | |
Avalon Eidolon and Krell, good match or not? Interestingly I almost wrote the same response Dave_b posted, I have been a regular attendee of th concerts @ Davis in SF and Herbst theater for many years.I have experience seating @ different sections but the sound that I heard in those events i... | |
6SN7 based Pre-Amplifier The Aria basic WV11 is still $6350.Not anyone can afford it.Since the thread starter is interested in 6SN7I could only recommend Melody 1688 Signatureor TubeCAD.com DIY boards for the Aikido 6Sn7 balanaced design) , or get Scott Frankland (local i... |
