| Line Stage Preamplifiers AX vs AU I was told that a 12BH7 can be used as a replacement for a 12AU7. Is that true? I've read notes about this compare, So I boughta bunch of 12BH7's, and none stood up to Tele 12AU7 as far as sonics, sound stage etc. As I mentioned above, there a... | |
| AR SP8 mk2 high output volume when I put the AR I notice a plus in terms of presence and forcefulness of the musicOK. I asked simply because with a high level signal like a CD player I would not have expected adding additional circuitry would have helped out. | |
| Line Stage Preamplifiers AX vs AU @yogiboy Yes, but you have to deal with the filament wiring, as the 12BH7 has a 12V center-tapped filament similar to a 12AU7. The 6CG7 can only be operated with 6.3V filament voltage. But the rest of the pin basing of the two tubes is the same, ... | |
| Is idler drive better than belt drive or direct drive? When he changes from TT to Tape, you don’t want him to go back to TT!@mglik If the LP was not a direct to disk then this is very easy to see. Of course a lot depends on what was used for playback of the LP in the example. | |
| Line Stage Preamplifiers AX vs AU @mozartfan You might want to hear what a 6SN7 does for a line stage. The 12AU7 is based on the 6SN7. Actually the 6CG7 is a 6SN7 in a miniature envelope, and the 12AU7 is the same geometry as the 6CG7 but with half the plate area. | |
| AR SP8 mk2 high output volume @tenoris Having looked at the schematic supplied by @imhififan I agree that essentially this amplifier is actually a power amplifier supplied with three inputs and a passive volume control. Since the control is 100K and given the characteristics o... | |
| AR SP8 mk2 high output volume I am using the Puresound A30 as a power amp because it is a possible option and so indicated by the manufacturer.I have just tried to use the Puresound attenuation as you have indicated and the result is quite satisfactory, with this volume at 1:... | |
| Is idler drive better than belt drive or direct drive? Better off with Reel to reel in the analog realm, going REAL low...Keeping in mind of course that the LP has superior LF response when compared to reel to reel. | |
| Two small RELs or One Larger Sub 1 sub good. 2 subs better. 3 better than that! 4 is best- this allows you to kill standing waves in the room. | |
| What tube amp for Harbeth 40.1 But ... it takes many tubes, it would add to the cost. I am not sure how expensive are the tubes ... @gte357s the power tubes are about 27.00 each. In a lot of cases a full set of them for our amps is less than one tube for some SETs!You will n... | |
| AR SP8 mk2 high output volume @tenorisWhy are you using a preamp? Your amplifier is an integrated amp. If its for the phono, use the tape output of the ARC instead of the main out- problem solved. | |
| Honest question about cartridge vs. turntable performance. Atma-Sphere, I will never ride a bike with anything but Campy on it. That Jap stuff is cheap overweight crap. It only worked better if you did not know how to shift. My current bike is a Specialized S works Diverge with Campy Super Record 12 s... | |
| Cartridge Opinions - Sorry please post your favorite tonearms, except for Triplanar and SMEFWIW while I had the SME5 for some years, It's not one of my faves, although the 12" seems to be pretty nice. The 4-point arms from Kuzma have worked well for me. The problem here is ... | |
| Is idler drive better than belt drive or direct drive? What is important is that the turntable have a robust drive that does not slow down when the stylus lands in the groove and the like. So the motor should have a bit of torque! You'll find that the most respected machines have this quality and this... | |
| Need highly transparent detailed amp---how does Pass XA25 compare to Gamut D100/D200 MKIII @lcherepkai If you like the sound of tubes, but really want solid state then my first recommendation is for a Pass Labs amp. |
