| SS amp with tight deep bass ? My recommendation would be a used Hafler XL600... Any BAT SS amp would be my second choice. I have compared the Hafler to many "super" amps...this one has the best LOW END punch/control I have experienced. Larry | |
| Upgrade CJ PV11 or Acurus L10 or buy CJ Classic? I can't tell much difference in sound between PV11 and the Classic, tube types make a larger difference than the circuits....to me. I would think a PV11 for $600 is a steal! You could always try different caps or resistors if you wanted to in the ... | |
| Amp, On A Budget? I have heard all of the amps mentioned and they are all very musical....but the only budget amp I have heard that does some of what the high end amps do both transistor/fet and modern tube amps is the last version of the Hafler amps....with Jfet d... | |
| Robin or Rodin Mod of an ARC SP3-A1??? HifiGeek1,I am commenting for my cousin who is traveling today. Together we both have an original SP3A-1 and I also own a SP-3C. Yes the SP3C sounds more modern....but late at night after the original warms up at least 3-4 hours.....wow...good by ... | |
| help with audio resesrch d76 HiFigeek1 you have sent myself and my fellow audio buddies on a wild goose chase.....for several days...we just thought we were dumb and didn't know how to ask you...Illuminate coupling caps???? We thought you knew an audio term we did not know...... | |
| help with audio resesrch d76 Hifigeek1 I need your help. What was the purpose of the "Servo" circuit? in the ARC 90B? Also, is the white/gray relay located down in between the large grey tall power supply caps? where the 6550 power supply tube was located in the 90? I do not ... | |
| Old NAD or newer high powered Denon? Pryso and Hifibear, sorry getting long winded. FYI the last versions of the Hafler amps with Jfet driver/Mosfet output play (not sound) my hard to drive speakers like a tube amp. When the absolute sound reviewed the XL280 the reviewer loved it but... | |
| Old NAD or newer high powered Denon? Pryso...I know. I'm a tube guy also... it is amazing how a good tube amp can "open up" speakers..especially with multiple drivers and complicated crossovers....and how a 30 watt tube amp can sound as "big" as a 200 watt transistor sometimes. FYI I... | |
| help with audio resesrch d76 Thanks HifiGeek!! I have never looked at the schematic for the original D90. Clearly shows matched GE6550s. I was fooled by the http://www.arcdb.ws/D90/D90.html website. Has a picture of D90 with GE6l6s in it. must be D90Revised...oh those ARC guy... | |
| Old NAD or newer high powered Denon? Absolutley!! If at all possible go for the SE240 120 watts per channel. This is a scaled down version of the XL280. Fewer mosfets in output stage (4 per channel) and simpler/small driver boards, but it has the same JFet input circuit. I have liste... | |
| Old NAD or newer high powered Denon? I would look for a higher powered NAD integrated....I have tried the high end Denons and Onkyos.....very thin/clean sound...preamp section doesn't touch robust NAD sound. Oh just a thought..if the 3020 has the preamp out jacks.....do what ever it ... | |
| help with audio resesrch d76 I own both....very similar driver circuits. The reason ARC came out with the D-90 is that Mr. Johnson's favorite sounding tube was the 6l6 (personal communication) That is one of the reasons he used the 6L6 in the ARC/Dynaco ST70-C mod. He told me... | |
| Just Purchased Infinity RS2B / RSIIb owned RS 2.5 Guys, thank you for your thoughts and input. Muzakk, I couldn't agree more that the higher and lower mids are wired to limit high frequency on the RSIIBs. I guess I got addicted to the beaming midrange of the 2.5s. I thought it was detail. To me t... | |
| Bias Setting for Older VTL 75/75 Well, with 80 views and no responses...I finally emailed EvaAnna....as usual she responded immediately with her usual quick wit.....and said . . . You should ask your "ace" technician what he did. I know she knows the answer... I asked my technici... | |
| Just Purchased Infinity RS2B / RSIIb owned RS 2.5 Well guys I feel like an idiot. I have listened to these "boring neutral" speakers compaired to my Infinity 2.5s for well over a year. . . . . and the other day I decided to look at the fuses. All 4 fuses for the emims and emits were sagging in th... |
