| Can a tube amp be damaged by a speaker switch? I have had transformer damage from the flyback effect years ago when I first started building tube amps and used a switch to compare them. From an engineering standpoint, paralleling a load (the speaker) with a resistor 10x or greater will have n... | |
| What record cleaner is the most bang for the buck?? Bought my VPI 16.5 over 20 years ago. Sure it's loud but it does a great job and makes a difference, especially if you bin-dive. For new albums I play them once first tyo help loosen debris left by the molding process. I also clean my stylus by... | |
| Recommend an Entry Level Turntable (And maybe an integrated Amp) Rega and Project are great for set-and-forget types, but if you want to swap carts and play around in general you need a removable headshell and adjustable VTA. Look at https://drop.com/buy/drop-audio-technica-carbon-vta-turntable. It has those,... | |
| Adding a SS amp as a 2nd amp for my tube rig has been a plus I run a Golden Tube SE-40 and a Pass Labs XA30.5... with Heresey IIIs on the first and LS50s for the second and dual REL 7Tis. | |
| Integrated amp suggestions. Pass Labs, anyone? | |
| Is there a Solid State amp that can satisfy a SET guy? I've got a Pass XA30.5 and a Golden Tube SE40. I'm rigged to switch between them depending on what I'm listening to. Both so good, but different. | |
| Best cheap integrated amp NAD - even the 316 sounds great for the money. | |
| Big source improvement using CD player - Anyone comparing mp3 to CD quality either isn't serious or has never done a straight-up comparison.- I've got an Oppo 105 that sounds great but why would I ever use it? My CDs are ripped to AIFF and my SACDs to DSD. My Brooklyn DAC sounds even... | |
| Best DAC for around $2,500 or less I like my Brooklyn, especially for the money. | |
| Who's done it besides me ? I have numerous vintage MMs, particularly Shure and Grado. I also have a bunch of MCs (mostly Denon but also Ortofon and Dynavector) and a Grado Statement Reference. They all sound good, in different ways, with the right stylus. It depends on t... | |
| old high end preamps.. The good blue Alps pots (Blue Velvet) were physically larger (maybe 1 1/2 times as big) than the ones you see now. The only place I see the old ones now is in stuff I built 15-20 years ago. | |
| What is the appeal of the Denon 103 cartridges? If# of turns primary - Np# of turns secondary - Nsprimary impedance - Zpsecondary impedance - ZsthenNp/Ns = square root of (Zp/Zs)Zp = (Np/Ns) squared x ZsJust Google "transformer impedance ratio" for the above formula.for a 1x10 transformer, Z... | |
| What is the appeal of the Denon 103 cartridges? Sorry - one more: That 2x impedance thumbrule only applies to stepup transformers. If you are using an MC amp stage, it's 10x. For the DL-103 that would be 400; some inexpensive phono preamps are fixed at 100 ohms or thereabouts. You would nee... | |
| What is the appeal of the Denon 103 cartridges? IMHO it takes a heavy arm for that low compliance (I use a Jelco 750 for them). Proper use of a step-up transformer really helps as well, and there is a lot of disinformation around. Some hints: 1) a transformer has no set impedance; it reflects... | |
| Can an IC based amp be considered 'high end'? No matter what you consider high end, most IC-based stuff can be improved by putting a Burson op amp replacement (made of discrete parts) in it. The amount of improvement depends on what chip was there in the first place but I haven't found any o... |
