Integrated amp and CD player for Tannoy speakers?

April 16, 2002

Can you suggest an integrated amplifier and CD player to get the most from the Tannoys Mercury M2 speakers? I am a great fan of music, especially classical, instrumental and vocals and looking to spend $1000 to $1200.

Have a look at the Arcam DiVA components. We reviewed the A65 on GoodSound! and it had many of the strengths you seem to be searching for. We also reviewed the matching CD72 on SoundStage!. This combination is priced within your budget and may just make those Tannoys sing.


Receiver shopping

April 15, 2002

First, congratulations on this site -- the information and reviews. I'm looking for a receiver that sounds great in stereo mode and for Dolby Digital and DTS. My first use is music, but I don't want two receivers. The problem is that I live in the Dominican Republic. Here, there is no NAD, Outlaw, or many others for audition.

I have Klipsch KLF-20 speakers. In your opinion, which of the following receivers will offer the best sound for music with large front speakers?

Outlaw 1050
NAD T751
Marantz SR-5200
Harman/Kardon AVR-520

Thanks in advance!

Denis

The Klipsch speakers are quite efficient, so you don't need a ton of power, but you do want clean power. The Outlaw is still a favorite because it offers tremendous sound quality and plenty of real-world, clean power. The NAD has quite a good reputation too. I'm not personally familiar with either the Marantz or Harman/Kardon models you mention.


Digital debate

April 14, 2002

I have a brother with a Ph.D in physics from Cornell. He's taken a number of courses in electrical engineering and circuitry during his studies. He's trying to convince me that any low-priced CD player will produce the identical sound to an expensive CD player if connected to the same system via the digital connection. He says that (to paraphrase) as long as there isn't some very cheap component in the buffer sending the signal to the digital output, the result will be identical because the very nature of digital sound is perfection (either there is a signal or there isn't, since the sound wave is approximated by discrete units instead of an analog wave that can easily be compromised). He said this is the whole reason why digital took off. Now you can have the ultimate consistency, and the sound of a $200 player will be identical to a $2000 player. Is this true? He said that he's written e-mails before asking if there was a measured difference in the result, but the reply was not that there were no measurement differences possible, but rather that the music just "sounded different." Of course, as you can imagine, this answer will never please a scientist whose life is based on actual measurable evidence. If there actually is a difference in the music, then it certainly can be measured. Otherwise we have a similar scenario as people impressed by the emperor's new clothes. Could you please give me your feedback on this?

Measurements certainly are the cornerstone of electronic design. The rub is, different engineers/designers interpret and weight different measurements differently. There have been numerous debates on the effect of digital jitter for example, an issue you should pose to your brother for his take on it. As well, we are still a ways off at having all the relevant measurements we need to accurately predict how something will sound to the ear. There’s little doubt that there is a measurement that can explain any audible characteristic, but it may be a measurement the engineering community has not yet developed or applied in a universally acceptable fashion.

In the end, you’re going to listen to a CD player, not measure it, so I’d let your opinion of its sound be the final determinant.


Help!

April 13, 2002

I have the Axiom M80Ti speakers, and they are powered by an Outlaw 1050 receiver. Even with the Outlaw's 65Wpc, I am not getting the bass I want, and the sound is harsh and edgy. I tried moving the speakers around, but this was no help. Maybe my room is too small (15' x 20' with cathedral ceilings). Do I need more power? Or should I exchange for the smaller M60Ti? Also, I used to use my M22Ti for the front channels, and they sounded better; they are now my surrounds. Any help or suggestions for this? I also use a KLH 10" powered sub.

Eric Theobald

I suspect the problem is likely with your subwoofer. Using the KLH sub with the M80Ti speakers may not be the best choice, as it is possible that there are some interaction problems (bass-canceling effects). If you are using the crossover in the 1050 to roll off the Axioms, then it's not surprising that you are not getting the bass you want. It would be much better to use the M80Ti speakers full range and the KLH just for the LFE channel on movie soundtracks. Or you could bring in the subwoofer under the mains, keeping the crossover set very low and running the Axioms full range. Either way, I'd experiment with the subwoofer as the culprit to your problem. Note that you experienced less problems with the M22Ti is not surprising, since they do not play as deep and would essentially avoid the interaction problems experienced with the larger speakers.


Digital or RCA connection?

April 11, 2002

Do I use the digital connection to connect my DVD player to my receiver, or the RCA outputs (the way I connect my CD player)?

Frank Muster

Typically you'll use the digital connection because you will decode both Dolby Digital and DTS using the decoders in your A/V receiver. There are exceptions though, most notably if your DVD player has built-in Dolby Digital and DTS decoders and incorporates one of the high-resolution multichannel audio formats. If this is the case, you can use the six-channel analog outputs of your DVD player (if you have DVD-Audio or SACD capability, you'll have these connections) and the corresponding inputs on your receiver (most late-model receivers have this feature). You will give up the DSP-based features within your receiver, if you choose to use the analog outputs of your DVD player exclusively.


Good advice on GoodSound!

April 10, 2002

GoodSound! has helped me so much! I can't believe how much good advice you guys have given. I've read almost all the letters and feel like I've learned more from them than from most articles I've read since I started to improve my audio system. Keep up the good work. Now if I can only think of a question you guys have not answered already!
