| Counterpoint SA-20 Amplifier agree. Output stage blew. Known problem with these units.Real SA20s are fixable with Exicons or Toshibas.SA220s.... other things on the bias / protection board are likely toast and impossible to fix.A lot of SA20s are actually SA220s.Check to see ... | |
| Best speaker that Proac ever made Owned 2, Heard 3, 3.5, D2.5, and 2.5. Liked 2.5 the most. | |
| Would u give up usher mini dancer 2 for b&w 802's Absolutely no for me. Though a bit nasal and bloated in the mid bass the ushers are drivable and has that very smooth yet transparent mid to extreme high. In comparison the 802 sounds very incoherent. | |
| Review: Tube Research Labs Dude Tube preamp Still using the Dude with Aesthetix Hybrid? | |
| Quad Esl 2905 reliability issues? Panel would be expensive. Try checking replacing the input bipolar lytic and the small 0.1uf cap somewhere midway between input and the panels. Sorry I forgot. Been too long. That fixed my 989. | |
| Speakers that sound like Usher Be-20s/10s Bol972's comments may be a tad hard to digest at times but I concur.The Rotel wont do justice to the "somewhat beryllium" tweeters. Don't get me wrong, the Ushers sound very good even with a scandalous less than pure Be tweeter.Woofers are hard to... | |
| ARC LS15: did they ever use Mundorf MCaps on it ? @Ketchup check out arcdb for the schematics of your line stage. Very easy inexpensive mod. If you put a scope right at the input of the regulator to look at the raw B+ you will see why I recommended a choke. | |
| ARC LS15: did they ever use Mundorf MCaps on it ? Just my own personal un/non-professional opinion but based on my experience with modding a few Audio Research units.Take out the whole output cap/0.01uF bypass combo, replace with 2.2 or 2.7uF Mundorf Silver Gold Oil or VCap TFTF. No need for 0.01... | |
| richard allan speaker set The RA Marimba was my first sucker pair of "audiophile" speakers in 1979. Nostalgic! | |
| Does Avalon speakers have a house sound? Extracting the crossover of a JBL or B&W or better yet Focal Utopia is completely different from trying to take out anything from an Avalon. I wonder how much sawing he did to take out the crossover and how much glueing and sanding to put it b... | |
| Does Avalon speakers have a house sound? Hi Bo, I think used Avalon owners all over the world would be interested in the serial number of that pair might be :)Scary cos there is no way you can access the crossovers without major hacking (literally). Scary.I do agree with you that violins... | |
| Do we still need 6550 or KT88 tubes? I second Knghifi's observation about those so-called GL KT88 reissues. They sound good but damn do they fail often and when they fail they fail with nasty shorts. | |
| Do we still need 6550 or KT88 tubes? Lower the bias on the kt120 and they won't be muddy. | |
| Avalon Indra, Eidolon, Opus comparison I have had ascents, monitors, eidolons, now diamonds. The ascents have a midrange magic that even the diamonds don't have. Not a fan of rockport or vandersteens. Hate Krell. Never heard any component as bad. But it's likely my bad hearing and inab... | |
| Avalon Indra, Eidolon, Opus comparison Vicdamone u sure you don't need to use any $50000 cables and tweaks to match the Eidolons?Kidding aside I think placement and linear power (triode amps) are the two main things. At least 60 inches away from the front wall and ceiling reflection tr... |
