Mini-Review of the Beresford TC-7520 DAC


Category: Digital

Looking for a feature-rich DAC with good sound and that won't break the bank? I recently stumbled upon a rather interesting find in this category. The Beresford brand has been popular Britain for the past few years, and there's a new US distributor that now sells their products direct online; a classified ad in Audiogon led me to their website called beresford-dac (along with a dot and a com in there somewhere). The TC-7520 is a 96/24 DAC with (1) USB, (1) Toslink and (2) SPDIF digital inputs (no analog inputs), a Class-A preamp with both fixed and variable outputs, and a headphone amp. Simple but elegant, the housing is a solid and compact black metal box with shiny gold metal soft-touch selector buttons (each with its own blue LED indicator), and incorporates a "dual" power supply (a combination internal and external components which is said to yield overall lower noise).

This unit has been installed as part of a home office system comprised of two-way TAD monitors (sporting built-in EL84 tube amplification) and an older Sony 5-CD changer with a variable line output which had been providing the services of both source and preamp. In comparison, driving the 7520 via the player's digital output offers a clearly audible improvement over the previous configuration; it serves up tight & tuneful bass control, more dynamic presence in the midrange, and a subtle smoothing of the treble. The headphone output's sonic traits are very similar. And as a bonus, a USB cable from my PC to the 7520 allows for a noticeable enhancement in music file playback. Bottom line, a very musical device; for $249, (shipping included), I think this one's tough to beat. (One note; Beresford USA does not offer a money-back satisfaction guarantee on these units, but once you see and hear it, you'll find it's an easy $249 to part with.)

Attention tweakers: The stock dual opamps are socketed, and I'd read on a couple of forums that these may be changed out with compatible devices that can offer further sonic improvement - But, be warned; according to Beresford USA, the unit's one-year warranty will be voided if ya mess with its internals in this fashion - So, best enjoy the TC-7520 in stock form first off, and then after 12 months have fun swapping in new opamps if you find yourself hankerin' for an upgrade.

UPDATE: It's come to my attention that Beresford USA has just begun offering a 15-day trial period along with the purchase of a TC-7520, so purchasing one is no longer a $249 gamble - A full refund will be given if a buyer decides not to keep the unit. (Check their site for further details.)
One more update: After 100+ hundred hours of play, this unit just keeps getting better and better - Just for fun a friend recently brought his DAC-1 over, and it turned out we both preferred the overall presentation of the TC-7520 (which is being used in a second system; my main rig contains a Cambridge 840C which by comparison tops both the TC-7520 and DAC-1). $250 including shipping directly from Beresford USA - Again, a no-brainer...
A must - replace the stock 5532 opamps, not with 4562, but try 4032, which will improve the sonics tremendously. The 5532 cannot sustain high orchestral passages, like in a concerto or symphony. It just breaks apart on congested high energy passages.
I've found the LM4562NA offers a very nice improvement over the stock 5532 - This DAC is now being used in my "System #2" as seen in the virtual system posts.
I agree. The opamp change brings about more detail and has a beter overall balance than stock (especially cleaning up some of the glare i the high freq.)

I was very impressed by the K Works modified Beresford DAC in demos at several audio club meetings. This is a unit worth rolling with mods costing several times its original price.
I purchased the Beresford TC-7520 from Beresford that was used as a magazine review w/the full warrenty @$229.00 w/shipping,such a deal. I was suprised to see it had some weight behihd it so the internal ps must be good. I am going to swap out the op-amps but listen to it for awhile before I start tinkering. It sounds beautiful connected to my pc then out to my Krell KSA-250 to Klipsch RF7's WOW!!!
Who need a preamp anymore with this beauty? It sounds awsome! The DAC makes my pc sound as good as my McIntosh MCD 201 with coaxial cable. It saves alot of space also.
I think I know what my daughter is getting from Santa this year.Just Wow!!!!
FWIW - I recently bought a used Beresford TC-7510, which is the model that preceded the 7520. It has 2 RCA and 2 optical inputs, and no USB input. My Beresford had been highly modified by a local modder, K-Works. K-Works calls this the SuperBerry DAC. K-Works' Igor Kuznetzoff feels the Beresford is a wonderfull platform for mods. I think it sells for about $1K new. I have to say this is a marvelous DAC. It is detailed, smooth, quiet and musical. In my local audio club, this DAC was put head-to-head with a $10K DAC from MSB, and most of those present declared it a tie. Although I don't doubt better digital sound can be had, I think it will require a lot of money to get it. For now, I am off the upgrade-go-round, at least as far as my DAC is concerned. My transport is a modest, but quiet, Rotel RCD-02.
I'd like to modify the opamps in my Beresford 7520, but I've never done this before. Is it difficult? Where do I buy the improved parts?
Question: if I would to connect the Rega Apollo to the Beresford TC-7520 (stock), how does it deliver better sound or musicality when the apollo has a newer and better dac chip WM8740 Sigma Delta 24bit?

I understand that if this dac is used with computer lossless source, I am sure it would make a world of different.

Also, as this dac does not have analogue inputs, I would be unable to link a Thorens TD-165 to this dac. As I do not have a head phones amp, I was really hoping that there might be a work around to allow me to listen to my analogue set up with this headphone out. Any suggestions? Should i be consider a phono stage with headphones out? Any recommendation?

My amp is the integrated Primare A10, which does not have phono or headphones out.
